We calculate the cost of wood concrete blocks. Where will a business plan for the production of wood concrete lead? Business for the production of wood concrete blocks

Arbolite is a stone artificially created from wood (chips, sawdust) and cement, which is usually used in construction. It is durable, lightweight, and holds finishing materials well. And the technology for its production requires purchasing only special molds and a concrete mixer. All this makes the business of producing wood concrete blocks attractive and profitable.

Types of arbolite blocks

The technology for producing wood concrete blocks requires the use of sawdust or wood chips, which are treated with a special compound and filled with a light cement mixture. In this case, the share of wood chips is approximately 85%, and cement – ​​15%. At the same time, both types of raw materials are inexpensive, which reduces the barrier to entry into the business.

The production technology has several variations, so there are two main types of wood concrete blocks:

• thermal insulation for wall insulation;
• structural and thermal insulation for the construction of walls of small buildings.

Arbolite blocks not only retain heat well. They are durable, flexible, and have excellent sound insulation properties. But the most important property that made it popular is its high environmental friendliness and low cost of material.

Technology for the production of wood concrete blocks

Depending on the strength, there are wood concrete blocks of the following brands: M5, M10, M15, M25, M35. The higher the brand number, the less chips it contains, and accordingly, the stronger the material. Therefore, for the construction of load-bearing walls of a one- or two-story building, grades M25 and M 35 are used.

To produce blocks you will need:

• Portland cement (grade 400 or 500);
• wood chips or sawdust;
• chemical additives (so that the filler does not rot);
• water.

The production plan includes the following stages:

1. Grinding wood chips or sawdust, drying in the open air for a month.
2. Dilute the required amount of chemical additives with water.
3. Loading chips and mortar into a concrete mixer, mixing.
4. Adding cement, mixing.
5. Add water, stir.
6. Pour the mixture into the mold.
7. Wait 3 days for the mold to harden, fold and leave for another 2 weeks to ripen.

To produce a cubic meter of wood concrete M15 you will need:

• 240-300 kg of wood chips;
• 12 kg of chemical additives;
• 250-280 kg of cement;
• 350-400 liters of water.

To make M25, the amount of cement should be increased to 330-330 kg. The hygroscopicity of the material should always be taken into account. Therefore, when using it to build walls, they must be additionally insulated from moisture.

Production premises

First of all, you need to choose a suitable premises for production. It is desirable that it be located near sawmills so that the necessary raw materials can be obtained quickly and inexpensively. The production itself is set up on an area of ​​at least 200-300 m2, on which a workshop, drying room and warehouse are organized.

The workshop must have a grounded industrial electrical network, installed fire sensors, and meet other requirements for fire safety categories A and B premises. It must provide a separate gateway for the supply of raw materials, shipment of finished products and a separate entrance for personnel.

Equipment

The business plan must include the purchase of the necessary equipment. Its productivity depends on the volume of the case. As a rule, the initial business plan involves the production of approximately 400-500 m3 of blocks per month. Accordingly, equipment for the production of wood concrete to start a business is selected based on these figures.

For work, it is not enough to buy a mini-machine for the production of wood concrete. Full work is carried out with the following equipment:

• industrial wood chipper;
• concrete mixer for stirring the working mixture;
• molding dispenser;
• vibrating table;
• drying;
• bunker.

Sales plan

It is important not only to properly organize production, but also to think about where to sell the finished products. You can sell blocks:

• large wholesale resellers;
• retail to the public;
• for construction organizations;
• sellers of building materials.

It should be taken into account that the main demand for products begins in the summer and lasts right until the fall. This is a period of active construction and site development.

Production costs

The main expenses included in the business plan will be spent on organizing the production line. Its cost varies between 50-500 thousand rubles. This amount does not include delivery, installation and commissioning of equipment. In this part, you need to include another 50-100 thousand rubles in the business plan. Raw materials must be purchased with a month's supply - that's another 600 thousand rubles. It will be cheaper to cook it yourself.

Another 300-500 thousand should be allocated for advertising for the year. It is necessary to spend another 15 million rubles to fill the dealer network. It is also necessary to provide for the salary of five workers and an accountant - approximately 140 thousand rubles. In total, 1.2-16.8 million rubles will be needed to start production. depending on the scale of production.

Every month production will require expenses for:

• rent;
• raw materials;
• communal payments;
• wages;
• taxes;
• Unexpected expenses.

As a rule, this amount amounts to 1.42 million rubles. per month.

Business income

If the business plan involves selling products at a price of 3.5 thousand rubles. m3, you can earn 1.75 million rubles per month. Taking into account deductions for general expenses, net profit will be 330 thousand rubles. That is, the investment can be recouped within six months of the enterprise’s operation. However, the final numbers largely depend on the region, level of competition, etc.

Production of wood concrete blocks: 8 reasons for organization + 8 success factors + product characteristics + market research + recommendations for the selection of raw materials + technology + workshop equipment + 3 equipment suppliers + organizational aspects + calculations.

There is a direct connection between scientific and technological progress and the emergence of environmental problems. Therefore, in the modern world, we have begun to pay more and more attention to nature and the environment.

At the same time, the business of producing environmentally friendly building materials has become relevant and in demand. This type of activity includes the production of wood concrete blocks, the main aspects of which we will discuss in this article.

How economically profitable is it to produce wood concrete blocks?

Arbolite (in common parlance wood block, sawdust concrete, wood bricks) due to its properties, performance qualities and purpose is classified as a building material.

The following components are involved in its production:

• cement;
• chopped wood (sawdust, straw, wood chips, shavings, etc.);
• water;
• chemical additives.

The decision to open an enterprise for the production and sale of wood concrete blocks is influenced by several positive reasons:

1. Production takes place using simple technology.
2. You can start a business first on a small scale and at home.
3. Compared to the production of other building materials, the production of wood concrete panels and blocks is not so financially expensive.
4. If you find cheap raw materials, you can achieve low costs.
5. This area is characterized by a large sales market.
6. There is a high demand for their wood concrete blocks, the value of which during the seasonal period may exceed supply.
7. Good payback period.
8. Block production is characterized by a long-term perspective and good profits.

To achieve economic efficiency from the business of producing wood concrete blocks, you need to understand a number of issues regarding the production process, product characteristics, analyze the market and the competitive environment.

Arbolite blocks, the production of which is listed by OKVED 26.65 and 51.53.24, can be sold without licensing activities. However, you cannot do without a quality certificate. Organizational and documentation issues will cost about 45-55 thousand rubles.

Success factors will be:

• providing the enterprise with reliable and high-quality equipment;
• hiring qualified employees aimed at high results;
• strict adherence to technology;
• production of only high-quality wood concrete blocks that meet consumer expectations and standard requirements;
• optimal price-quality ratio;
• establishing relationships with suppliers of raw materials and construction companies that will purchase blocks in large quantities under a contract;
• use of other sales channels, organization of active sales to other Russian constituent entities or regions;
• choosing the right positioning, competent marketing policy.

Characteristics of wood concrete blocks, product range

Also, wood concrete blocks are assigned certain classes based on their compressive strength.

Gosstandart stipulates the production of blocks of the following dimensions:

• 50x40x25 cm;
• 50x30x25 cm;
• 50x20x25 cm.

Arbolite blocks are classified into thermal insulation type And structural.

The first type of material has low strength (400-500 kg/cubic m). It is marked with the letters M5, 10, 15. Structural blocks have increased density, and therefore strength. These are wood concrete products M25, 35, 50. The minimum density limit for such blocks is 500 kg/cubic. m, maximum – 850 kg/cubic. m.

Arbolite building materials can be produced monolithic or hollow.

The blocks are used for construction purposes. Arbolite thermal insulation materials are used as wall insulation and sound insulators, and structural blocks are used in the construction of houses and other low-rise buildings.

Arbolite products are highly useful and are valued not only in Russia, but also abroad as a heat- and energy-saving material.

The advantages of blocks are:

• versatility,
• environmental friendliness,
• durability,
• sound absorption,
• strength,
• ease of construction,
• thermal conductivity,
• ease of processing.

Due to its versatility, the production of wood concrete products is beneficial for the construction of private houses, industrial buildings, as well as bathhouses and cottages. Such blocks are used on sea coasts, in Siberia, etc.

Arbolite blocks have a porous structure, which means that the structure erected with their help “breathes.” Expanded clay concrete is inferior to wood concrete blocks in terms of thermal insulation properties. Sawdust concrete is preferable to bricks and foam blocks, because does not crack under heavy loads.

The main thing is not to exceed the maximum permissible limit. One block weighs 15-60 kg. Thanks to this, the foundation of the structures is light, unlike brick buildings, which allows saving on construction work.

Since wood concrete products contain cement and other components in addition to wood chips, the blocks do not ignite like wood and are not susceptible to rotting or attack by bacteria. If fungal spores actively multiply when they come into contact with concrete, stone, brick, wood, then this does not threaten the wood concrete blocks.

They are easy to process; cutting is carried out using a hand, gasoline or electric saw. There is no need to pre-drill blocks to screw in self-tapping screws and drive nails. Wood concrete products are also easy to install.

1. Market research in the production of wood concrete blocks.

Arbolite blocks gained popularity in the Russian Federation at the end of the 20th and beginning of the 21st centuries. Today, their production is also in special demand, which is facilitated by the development of private low-rise construction.

There is a reorientation towards building materials that would not only have standard characteristics, but also meet modern requirements:

• environmental friendliness,
• operational processing,
• light weight,
• ease of use,
• energy efficiency.

Arbolite blocks meet the basic requirements, resulting in prerequisites for stabilizing demand. The production of wood concrete products on the territory of the Russian state is established by many companies.

Major market players that can compete are:

In total, 83 companies are currently registered in Russia. Of these, 72 work in the Volga Federal District, 5 in the Central Federal District. 2 carry out production in the Siberian Federal District, another 2 enterprises are located in Blagoveshchensk and the Amur Region (FEFD). There is 1 company each in the North-Western and Ural districts.

2. What raw materials are used in the production of wood concrete blocks?

The initial stage of production comes down to preparing all the components that will form the basis of the wood concrete blocks:

• The filler is prepared from crushed wood, maintaining a 1:2 ratio.

Make sure that wood products are sufficiently dry. To achieve the required consistency, sawdust and wood chips are kept for about 4 months. on open air. They need periodic stirring and treatment with lime mortar.

• 1 cu. m of wood raw material is watered with a 15% solution in a volume of 200 liters.
• The chopped wood is left untouched for 4-5 days, and then mixed at least twice a day.

Such operations play an important role in the production of wood concrete blocks, because They help remove sugar from sawdust, which later leads to rotting. As an alternative to lime, other chemical additives are used: liquid glass, calcium chloride, aluminum sulfate. The chemical additive is added to the wood concrete mixture in liquid form.

Raw materials are purchased from enterprises operating in the logging industry, or they are made independently using a wood chipper. The size of wood raw materials for wood concrete blocks should be as small as possible, then it will be possible to achieve greater strength after drying.

If you intend to organize a serial production, it is better to purchase special equipment for drying and grinding wood. In order for the wood concrete blocks to be of good quality, you need to purchase coniferous tree chips.

Can be used:

• aspen,
• poplar,
• alder,
• birch,
• maple,
• ash.

Allowed:

• common cotton plant,
• lignified parts of flax,
• kenaf,
• hemp,
• straw,
• larch.

In the latter case, the volume of chemical additives introduced for the purpose of processing wood waste increases by 2-4 times in comparison with those applied to conifers.

To produce blocks you need to buy high-quality cement. Focus on M400, M500. Sometimes sand is present in the recipe. His choice also needs to be approached responsibly. To prevent blocks from sagging during production, washed river sand is used.

Technology for the production of wood concrete blocks: process features

The recipe for raw materials is not easy to determine. This must be done by an experienced technologist. Without his help, using an experimental method, you can choose the wrong dosage of components and disrupt the entire production technology.

The raw material mass was developed in the ratio shown in the picture back in the Soviet Union. It is more economical than others, because allows the use in production of secondary filler, which is obtained from particle boards.

Such a filler does not need to be pre-treated, so less energy resources are spent, the production of wood concrete products becomes less labor-intensive, the environment improves due to waste disposal, and the range of building materials is expanded.

Arbolite blocks can be made in 2 ways, which are worth considering in detail.

Method number 1. Tamping by hand on the floor - most economical

To produce using this method, buy a forced-type mixer and a tank where chemical additives will need to be diluted.

In addition, you will need containers with a measuring ruler for loading wood chips and cement into the mixer, and steel forms that serve as a place for compacting the wood concrete mixture. Wood concrete is transported to the forms using a trolley.

The surface of the floor on which the production stage, such as the formation of blocks, takes place must be flat, plywood or concrete. In addition, the company is provided with pallets designed for stacking finished wood concrete blocks.

Method number 2. On a machine, vibration with a weight is more rational for large production volumes.

These machines are difficult to find on the market, but you can negotiate with an industrial enterprise to produce the equipment according to your order.

1. Dirt-free chips corresponding in size and composition to Gosstandart 19222-84 are immersed in the mixer.

Please note that sawdust cannot be used fresh! If you cut the raw material yourself, let it dry for about a month after chopping.

2. Then a solution is made from chemical additives and water.
3. When this procedure is completed, the mixer is started. The resulting solution is added to it, and the wood chips are stirred for 20 seconds.
4. Only after this can you start adding cement. This is done in such a way that the cement mixture covers the entire area of ​​the crushed wood.
5. The mass is mixed well for 3 minutes. Water is no longer poured into the mixer container, because... this action will lead to the production of wood concrete blocks of insufficient strength.
6. The pallets are placed next to each other on the vibrating platform of the machine. One general form is placed on them, which must be fixed during the production of blocks for the machine.
7. Afterwards, the wood concrete mixture is poured into it, and pressing occurs with a loss of 30% of the previous volume.
8. The mixture is kept in the formwork for some time to harden, then the blocks are removed and left in a warm room for 10 days. It is allowed to stack blocks one on top of another in 3 rows.

To apply more wood concrete products, another 7 days must pass. Transportation is carried out two weeks after the production of wood concrete blocks, if the weather is dry. In rainy, damp weather - after 20 days.

So, the production of wood concrete blocks can be described in 4 main stages:

In order for sawdust concrete to be of high quality, it is necessary to organize incoming control of incoming raw materials in production.

Equipment for the production of wood concrete blocks: technical equipment of the enterprise

Equipment is purchased depending on what technology was chosen for the production of wood concrete blocks, based on the raw materials used and the desired output volumes:

Equipment		Purpose
Machines DU-2, RRM-5, MP-500 and analogues		For cutting wood. Hammer mills, wood chippers, and DM-1 type units crush raw materials more thoroughly.
Vibrating table		Necessary for cleaning wood chips from bark, pieces of dirt, and earth.
Paddle or cyclic forced action mixers		The mixture for arbolite blocks is prepared in them.
Concrete distributors / lifting stations		For transporting the finished solution to the molds.
Brick presses Condor, Rifey, etc.		For compacting blocks.
Thermal cameras		With their help, complete hardening of wood concrete products is achieved. They can be equipped with IR emitters, heating elements and allow you to set the level of humidity and temperature required for the production of blocks.
Forms		They are selected in accordance with the dimensions of the wood concrete materials that you are going to manufacture. You don’t have to purchase them; you can make them yourself from boards 2 cm thick. After they are knocked into certain sized shapes, the inside is covered with a layer of plywood, then with a layer of linoleum/film.

If you are making blocks at home, you will need the following kit:

• serving table;
• vibrating table;
• chip catcher;
• detachable metal forms and inserts attached to it;
• shock-shaking table;
• dispenser of crushed wood, cement;
• vibroforming machine;
• installation that lifts forms;
• pallets;
• tray for receiving wood concrete mixture.

With such a list of units, you can achieve good production volumes in a month (about 300 sq. m). To place the equipment, you need 500 sq. m area. In this case, only 15-40 kW/h of electricity is consumed.

In the case of large-scale industrial production, it is better to buy a highly automated line that produces wood concrete blocks and includes all the necessary mechanisms.

Such equipment for the production of wood concrete blocks can be in different variations and configurations.

The standard package includes:

• concrete mixer,
• chipper,
• pallets,
• drying chamber
• Press forms,
• vibropress.

Production on powerful installations allows the production of up to 800 blocks in one 8-hour shift. The cost of these reaches 1.5 million rubles.

Industrial equipment can be purchased from the following companies:

"Arbolit" ( https://www.arbolit.com/Zapusk-proizvodstva-arbolita).

The company is ready to offer lines for the production of wood-cement blocks: Liga-Avtomat, Liga-7, Liga-8U, etc. Arbolit provides services for commissioning, training of workers, production of a trial batch.

The units are characterized by ease of operation and ease of use, compactness, low payback period, full use of wood waste, and a small number of maintenance personnel.

"Russian wood concrete" ( https://ruarbolit.ru/oborudovanije).

Since 2006, the company has been designing and selling ready-made lines intended for the production of wood concrete products.

The company's equipment is characterized by moderate price, reliability, but low productivity. The kit may not include a woodchip chopper. The units are small in size, so they can be easily located in workshops with low ceilings.

OKB Sfera LLC.

The plant produces complexes for the production of wood concrete panels and blocks, which are highly mobile and productive, easy to maintain.

What kind of room can be equipped for the production of wood concrete blocks?

It is more economical to rent a room.

For the full production cycle to occur under normal conditions, the site must have:

• work space (from 100 sq. m);
• the area where the blocks will be dried (approximately the same area);
• storage space (within 150 sq. m).

You will also need an area where wood raw materials, other components of the recipe, and parts are supposed to be stored. An area half the size of the working area is sufficient.

In addition, it is necessary to place the director of the enterprise. Therefore, it is necessary to allocate areas in the premises for offices of administrative and production personnel, for a restroom, and an office. The total area should not be less than 430 square meters. m.

Rent, on average, will cost approximately 85-100 thousand rubles. Payment is usually made immediately for the first quarter.

The premises selected for the production of wood concrete products must meet a number of requirements:

When looking for premises, pay attention to those that are located near the sawmill. This way you will provide production with a constant source of raw materials and save on the costs of its delivery.

An important factor influencing the choice of site is the availability of a transport interchange. Wood concrete blocks should be transported from the enterprise without problems, and this also applies to the delivery of cement and lime.

There are also a few things that need to be said about the premises:

• It is advisable that its ceilings be at least 5 m high, otherwise you will have to worry about finding suitable equipment.
• It is imperative to maintain a certain temperature, especially in cold weather (15-20°C).
• At the same time, the building must comply with fire safety categories A and B.
• If an entrepreneur has the opportunity to establish his own logistics, he will need a garage for vehicles.

Labor resources at an enterprise for the production of wood concrete products

The number and composition of personnel is influenced by what equipment was purchased.

There are complexes that are serviced by 3 people. Other installations that produce wood concrete blocks require an increase in the number of personnel - usually up to 5 people.

The workshop owner regulates the operating hours of the workshop himself in accordance with the labor code. Approximately 40 hours per week + 2 days off.

To ensure normal conditions for the production of wood concrete blocks, you need to hire at least 4 people. In addition, we need a director of the enterprise, whose position can be assumed by the owner. The services of an accountant will be required.

The staff must also have:

• supply and sales manager,
• technologist,
• driver and loaders for delivering blocks to customers.

How to organize the sale of wood concrete blocks?

When the sale of wood concrete blocks is carried out without intermediaries, mark-ups on products are eliminated. Finding clients is another important goal of an entrepreneur, because... quick payback and good profits can be achieved by selling all produced blocks.

Demand for wood concrete products falls at the end of autumn and appears when construction work resumes. To eliminate downtime, you need to find wholesale customers and sign contracts with them for the supply of blocks.

Arbolite products are purchased:

• construction companies;
• private individuals;
• hypermarkets and construction warehouses;
• contractors.

If you reduce the cost of wood concrete blocks and overhead costs, but do not degrade the quality, you can sell them 15-20% cheaper than competitors. This way you will attract more buyers.

When promoting your business you should use:

• In the first case, they resort to the media, outdoor advertising, distribution of leaflets and booklets, and exhibitions. Printed products should be distributed in supermarkets and places where there are large crowds of people.
• When promoting online, it is advisable to create your own website (landing page), use contextual advertising, banner advertising, targeting, and social networks.

Try to stand out from your competitors not only with a more attractive price per block, but also with various interesting offers. For example, allow early customers to receive a free sample. They will see for themselves the quality of wood concrete products and, most likely, they will have good reviews about you, and then word of mouth will do its job.

Investments in wood concrete blocks (production)

1. The main cost items in the production of wood concrete blocks.

• Business registration, certification – 45 thousand rubles.
• The rent for the quarter is within 300 thousand rubles.
• Equipment costs depend on the option you choose. If you buy a new line, the costs will be about 1.5 million rubles. You can purchase units separately, either used or leased. When purchasing equipment for making blocks in parts, you will have to pay up to 600 thousand rubles.
• Raw materials should be taken with a reserve - at least 1 million rubles.
• Payroll – 160 thousand rubles.
• Advertising campaign (for the first 3 months) – 180 thousand rubles.
• Preparing the premises, purchasing furniture, PCs, MFPs and other office equipment (telephony, Internet) – 220 thousand rubles.
• Utilities - 80 thousand rubles.
• Taxes – from 48 thousand rubles.
• Unforeseen expenses - 100 thousand rubles.

If we sum up all the costs, to open a workshop for the production of wood concrete blocks you need at least 3,633,000 rubles. Monthly costs will result in 1,548,000 rubles.

Production of arbolite blocks.

What is wood concrete? Pros and cons of this business idea.

2. Income from production.

Depends not only on fixed/variable costs, but also on production volumes.

When, for example, 14 thousand units of wood concrete products are produced within a month, the revenue will be 2,380,000 rubles:

• The sale of one wall structural block (size - 30x40x60 cm) is carried out at a price of 170 rubles.
• Net income will be equal to: 2,380,000 – 1,548,000 = 832,000 rubles.
• With good sales, a business will pay for itself in an average of 4-6 months.
• Profitability – 35%.

Naturally, in practice the numbers will not coincide with yours, since everything is averaged. These are rough estimates. In addition, each region has its own prices.

Strive to develop a competent sales policy, and then the production of wood concrete blocks will help you take a strong position in the market and increase profits.

Arbolite is a thermal insulation material that is an excellent analogue of more expensive thermal insulation products. It is environmentally friendly and safe. That is why the production of wood concrete, the business plan of which is quite simple to draw up, will be a very good idea for a profitable and successful business. Let's look at what expenses and profits you should prepare for.

Benefits and Potential

You can create both small and larger arbolite blocks. The first option is actively used for arranging partitions inside a building and as an insulating layer, and the second option is used for constructing load-bearing walls of a structure.

A well-drafted business plan for the production of wood concrete blocks will allow you to get an enterprise with several significant advantages in the future:

• Constant opportunity to sell products, which is associated with active development.
• With competently conducted marketing research, you can objectively assess not only the capabilities of competitors, but also your own potential for further development.
• The production of wood concrete does not require the purchase of overly expensive raw materials, which reduces the cost of starting a business.
• This also applies to equipment that is required in a minimum quantity.

If you think through this type of business to the smallest detail, then all the funds spent on the activity will pay off fairly quickly.

• Establish connections with companies engaged in repair and construction work.
• Sign contracts with large wholesale enterprises that will sell products made from wood concrete to other regions.

This strategy will provide an opportunity to receive stable and high profits.

Business organization

A business plan for the production of wood concrete blocks involves searching for the optimal size and conditions of the room in which the creation of the material will take place. In this case, the premises can be either rented or built from scratch. Whatever option is chosen, the room must be large enough and have high ceilings to accommodate large equipment.

Equipment selection

To organize your own business for creating wood concrete, you will first need to take care of purchasing a functional and reliable one. When making purchases, you will need to take into account that equipment from domestic companies will cost several times cheaper than imported ones, but thanks to it, it will be possible to obtain no less high-quality wood concrete.

To create a good and durable wood concrete, the business plan must include a fairly affordable and simple set of equipment:

• a special mixer for mixing the components of the material;
• pressing molds;
• set of tampers;
• an oven in which the resulting blocks will be dried;
• hand trolley for transporting finished blocks.

The total price for such a kit will average 600,000 rubles. Moreover, the equipment is capable of producing 20 cubic meters per day. m. material.

Purchase of raw materials

To organize successful production of wood concrete, you will also need to take care of ensuring a stable supply of all necessary raw materials. It includes the following components:

• wood chips;
• sand;
• Portland cement;
• To neutralize sugar, you will need to additionally purchase aluminum sulfate.

The strength of the wood concrete blocks themselves will directly depend on the quality of the selected raw materials. That is why you should not save on all the materials listed. Otherwise, customers will very quickly become disappointed in the product and refuse to purchase it further.

Approximate costs

To start an activity in the production of wood concrete blocks, you will definitely need start-up capital. Its dimensions directly depend on the scale of production, as well as on the power and equipment manufacturer.

For the production of wood concrete, the business plan specifies the following main expenses:

• Payment of rent for production premises, which will be within 90,000 rubles.
• Payment of wages for all employees of the enterprise is about 120,000 rubles.
• Purchasing a standard set of equipment for organizing a production line can cost 400,000-600,000 rubles.
• Purchase of raw materials and various additional materials, which will cost another 600,000 rubles.

The work of such an enterprise must occur daily, which is why all employees will have to use a shift schedule. To ensure that already produced products do not sit in the warehouse, you need to find customers in advance who will immediately buy them. And this is an additional advertising campaign, which will also cost a certain amount - about 15-20 thousand rubles.

Economic efficiency of the production of wood concrete blocks using the Automated Line SGS-L4.

General information.

Today, when so much attention is paid to the environment, the production of environmentally friendly and at the same time warm, light, high-quality and reliable materials is very relevant and in demand, so we have developed a technology for the production of wood concrete blocks using SGS equipment.

Arbolite blocks are well known and widely used abroad. They are highly valued for their energy- and heat-saving, sound-absorbing properties. In different countries, analogues of wood concrete have their own names:

. "Durizol" - Switzerland; "Woodstone" - USA, Canada;

. “saw concrete” - Czech Republic; “Centeri-boad” - Japan;

. "Duripanel" - Germany; "Velox" - Austria;

These materials are used to build not only private houses, but even high-rise and industrial buildings.

Properties of arbolite blocks.

The main dimensions of arbolite blocks are 200*300*600 mm and 200*300*500 mm.

1. Versatility. You can build houses, cottages, and baths from arbolite blocks. Wood concrete was used in the construction of buildings in Antarctica, beyond the Arctic Circle, on sea coasts, in central Russia and in Siberia.
2. Environmental friendliness. Wood concrete blocks combine the best advantages of wood and the strength of concrete. A house made of wood concrete “breathes” thanks to the porous structure of the blocks.
3. Thermal conductivity. Wood concrete has better thermal insulation properties 3-4 times than expanded clay concrete, and 6-8 times than brick.
4. Strength. If the load exceeds the maximum permissible, cracking of wood concrete blocks does not occur (this problem is typical for foam blocks, bricks and aerated concrete blocks). The strength grade of wood concrete blocks is from M20 to M50.
5. Soundproofing. Arbolite walls have a high sound absorption coefficient, the range can be 0.17-0.6 for sound frequencies of 125-2000 Hz. For example, brick walls have a sound absorption coefficient of 0.04 at 1000 Hz, while for wood this ratio is 006-0.1.
6. Ease. Block weight from 15 kg. When building a house from wood concrete, lighter foundations are used than when building a house from brick. There are significant savings in construction.
7. Fire-biological resistance. Arbolite, unlike wood, does not burn, does not rot, and is not susceptible to fungal attack, thanks to the cement shell.
8. Ease of processing. Wood concrete blocks are sawn with a regular gasoline, electric or hand saw. Wood concrete holds nails and screws well. At the same time, it does not require preliminary drilling or processing.
9. Durability. Many buildings and structures built back in the 60s still serve their owners to this day.

Calculation of the cost of an arbolite block of strength grade.

To produce 1 wood concrete block, the following components will be required:

*The salary for 5 workers is 5 rubles per unit.

* If you use your own wood chips, you save 9.6 rubles. from the block.

Water consumption is adjusted under production conditions, taking into account the moisture content of the sand.

As can be seen from the table, the cost of 1 wood concrete block is 48.9 rubles.

Cost calculation 1 m³ arbolite blocks

strength grades.

To produce 1 m³ of wood concrete blocks, the following components will be required:

*Water for preparing the wood concrete mixture from the local pipeline.

*The salary for 5 workers is 5 rubles per block. There are 28 blocks in 1m³.

*If you use your own wood chips, you save 268.8 rubles. from 1 m³.

As can be seen from the table, the cost of 1 m³ of wood concrete blocks is 1369.21 rubles.

The cost of selling 1 m³ of wood concrete blocks is 4,200 rubles.

Composition of the SGS-L4 Automated Line for the production of wood concrete blocks:

1 - Concrete mixer SGS-M245; 2 - Belt conveyor with receiving hopper; 3 - Storage hopper-dispenser; 4 - Vibropress SGS-3 wood concrete.

Calculation of electricity consumption per 1 m³ of arbolite blocks

Final calculation:

**Taxes and rent of production premises, advertising and loading and transportation costs were not taken into account in the calculation.

* The calculation data is based on a productivity of 35 m³ or 980 blocks per shift.

Comparative analysis of arbolite blocks

The use of wood concrete in construction compared to traditional building materials is economically justified and has a number of advantages:

Relatively small capital investments for the construction of one square meter of structure;

Buildings built from wood concrete are safe for human health and the natural environment;

The construction time of buildings is reduced;

Operating costs for heating and ventilation are reduced. The house is breathing.

Technical characteristics of arbolite blocks

Comparison by thermal performance indicators

We will carry out a comparative calculation of the cost of building a frame house from wood concrete, brick and foam blocks without taking into account the cost of the foundation, floors and roofing.

Let's take a house with an area of ​​200 sq.m. size 10x10 m, 2 floors, floor height 3m. The area of ​​the walls of this house will be = 240 m2. Let's calculate the total number of blocks = 72 m3. All 107 m3 of brick will be required because the brick wall must be thicker. The brick must be insulated, the cost of materials for insulation is 552 rubles/m2. plus the cost of insulation work 790 rubles/m2. The wood concrete will need to be plastered; the cost of plastering the walls outside, taking into account the materials, is 350 rubles/m2. Let's put the data in a table and see - wood concrete is beyond competition. Simple arithmetic operations show the direct benefits of using this unique building material. Build a house from wood concrete - save money, because it’s so hard to earn.

Construction of houses from wood concrete

*The cost of construction of 1 m2 given in the table includes the cost of all work and materials, taxes and overhead costs, but does not take into account the delivery of materials to the construction site.

Thus, such grades of wood concrete as M5, M10, M15, M25 and M35 are known. To build a one-story house or to complete the upper floor of a house, it is enough to use wood concrete marked M15, and to build the lower floor in a two-story building, it is better to give preference to wood concrete M25. The brands differ in strength, which in turn directly depends on the amount of cement in the original mixture.

If your goal is the production of wood concrete, a business plan for which you have already drawn up, then now it’s time to understand the sequence of technological operations in the production of this material:

1. 1. First, you should prepare, that is, grind the aggregate. It is important that wood waste must be crushed in positive temperatures under a canopy and in the fresh air. The grinding period is equal to a length of at least 1 month.

Granules measuring 10–20 mm should make up no more than 70% of the total volume, those less than 10 mm - 30%, and bark and leaves of pine needles are allowed only 5%.

You can also safely “mix” waste from crops such as flax or hemp with wood waste, after treating it with lime mortar.

1. 2. the stage of diluting chemical additives in water until they are completely dissolved.

1. 3. Loading cement. Mix thoroughly.3. Loading the filler into a concrete mixer and adding a solution with chemical additives to it. Mix thoroughly.

1. 4. Water supply (water is supplied gradually, in small portions). Mix thoroughly.

1. 5. The resulting mixture is poured into a mold, which is used to make cinder blocks - if blocks are needed. If the construction is monolithic, then the mixture is poured into the formwork. Well, if you are waiting for frame construction, then the mixture is sent to harden in a special frame.

1. 6. The mixture is compacted, but it must be compacted so that there remains a distance of at least 20 mm to the edge of the mold or formwork.

1. 7. You can move the form only after three days. Give it another 2 weeks to harden, and you should protect the molds from precipitation by moving them under a canopy or specially covering them.

Approximate ratio of materials in the production of wood concrete per 1 cubic meter of M15 grade:

• - Cement M400 or M500. You will need from 250 to 280 kilograms.
• - Organic filler weighing from 240 to 300 kilograms.
• - 12 kilograms of chemical additives.
• - Up to 400 liters of water.

If you plan to produce more durable wood concrete M25, then the amount of cement increases to 330 kg.

In any case, the material cannot but have disadvantages, and if you plan to make money through the production of this material, then you must be prepared for all the pitfalls. The main and, perhaps, the only drawback of the material is its hygroscopicity.

The material easily absorbs moisture and is just as easily destroyed under its influence, so it is strictly not recommended to be used as a basis for a foundation or blind area. And walls made of this material must be generously provided with waterproofing.

If it is expensive and unprofitable to insulate the walls, then you need to increase the roof overhangs by at least 0.5 meters so that precipitation does not touch the walls and destroy them.

As a result, one cannot but agree that the production of wood concrete is very profitable and a business based on the creation and sale of this excellent structural material is simply doomed to success, since the advantages still outweigh the minor disadvantages of the material.

After all, a material that is so environmentally friendly, that would have such high heat-insulating properties and would be so inexpensive, still needs to be looked for very carefully.
