How to find out how much a bucket of sand weighs. Theoretical conditional weight of a bucket of sand for a standard product. A simple method for calculating the mass of a sand mixture for buckets of non-standard capacity and any other volumes. The specific gravity of the sand, the density of the sand mixture, the bulk density of the sand material.
We will decide immediately: to find out exactly how many kg (kilogram) a bucket of sand weighs, you can find out only by weighing it on the scales. This is the so-called OBJECTIVE METHOD, giving the most correct result. All other methods for determining the mass volume of the sand material give an approximate or theoretical weight of a bucket of sand with a significant error. The main problem of the calculation methods for calculating the mass of granular matter, in this case, a sand mixture, is that they are based on knowledge of the density of the material (soil). And with the density of sand mixtures, everything is really very complicated and confusing. It’s not even that finding the exact value of the density of the sand is still that problem. Such a parameter as density or specific gravity (it is also bulk density) in sands varies too much (varies) depending on a number of factors. The main ones are: mineralogical composition, humidity (water saturation), grain size (grains of sand, solid particles), the presence of impurities related to clay and dust fractions and compactness of the sand mixture (friability). If we knew exactly what kind of sand we have and what parameters our sample of sand material (soil) is characterized by, we could, at least theoretically, use the exact data from the corresponding table of densities of bulk solids and correctly, without error It is easy to calculate the weight of a bucket of sand. However, it is unlikely that the site visitor has such detailed information about the characteristics of the existing sand material. Nevertheless, I would like to know, at least approximately, how much a bucket of sand weighs. The easiest way is to look at the mass values \u200b\u200bof the sand mixture in our table 1. Find in the leftmost column the desired type of sand mixture by name, and in the far right column the data is given: how much a bucket of sand of this type weighs. Comfortable enough. With one caveat.
Buckets are different in volume, respectively, and there must be different values \u200b\u200bof the mass of the sand mixture located in the volume of the bucket. How to be in this situation? Firstly, in our table 1, the capacity of the bucket in liters is indicated, for which the weight of the sand mixture is given. Secondly, we will talk about a method for calculating the mass of sand in a volume based on density, the data for which are also shown in table 1. It is very simple and based on the conversion of the amount of sand in 1 m3 to the weight of a liter of sand mixture. Knowing the weight of 1 liter of sand mixture, you can easily calculate the weight of a bucket of sand in your existing tank. In 1 m3 (cubic meter, cubic meter, cubic meter) of any sand ALWAYS contains exactly 1000 liters of bulk material. Table 1 gives the number of kilograms (kg) in 1 m3 (cubic meter, cubic meter, cubic meter) of sand mixture of each type. How many liters of bulk material is placed in your bucket, you know, as a last resort, look at the markings on the product. How many kilograms (kg) in 1 m3 take data from our table and make a proportion that will allow you to independently calculate the weight of sand in a bucket of non-standard capacity. I remind you that the accuracy of this method for determining the mass of bulk material is rather approximate, but the error is not due to direct weight calculations, but because most likely you will not be able to accurately indicate the parameters of your sand mixture. On the other hand, for domestic needs, independent construction and manufacturing of non-essential products, structures and structures, the method of calculating volumetric mass based on the density of bulk material turned out to be convenient, practical, and is widely used. In addition, this option for calculating the volumetric mass of sand material (soil) does not require complex mathematical calculations, and it is difficult to make a mistake.
How much does a bucket of sand weigh. The weight of a bucket of sand? See the answer in table 1.Table 1. How much does a bucket of sand weigh. The weight of a bucket of sand. .
How many buckets in a cube of concrete. Recalculation of container volumes into cubic meters is a common task that causes some difficulties.We understand that 1 cube (1 m3, 1 cubic meter, 1 cubic meter) is a unit of measure for volume. It should be understood that any volume in itself can be considered without being “tied” to specific gravity measured substance. Psychologically, this causes some difficulty or concern. For us, it often seems that volume is rather the amount of substance, which means that we must somehow take into account the weight. Not. Recalculating the volumes of any container into cubic meters is a purely mathematical problem, the solution of which is based on the proportion. What proportion allows us to recalculate one volume to another? The most convenient way is to convert to liters (or liter cans). We know how many liters are in our bucket and we know how many liters are in one cubic meter. This is the basis for making proportions. For example: 1 cubic meter of concrete always contains 1000 liters of concrete.
But with buckets, the situation is more "confusing." It is generally accepted that there is a certain standard capacity of a bucket in liters. This is actually not the case. According to GOST and TU of packaging manufacturers, buckets can be produced in several modifications and, strictly speaking, the manufacturer of metal products, galvanizing, plastic, does not have to comply with any standard capacity. Rather, the situation is that the enterprise is obliged to indicate in the product labeling its capacity in liters. Usually this rule is observed, especially for iron buckets. If the labeling does not indicate the volume of the container, then its capacity must be installed independently. It is easiest to do this experimentally using a standard glass jar with a volume of 1, 2 or 3 liters and any liquid or bulk material.
The matter is simplified by the fact that in practice, all container manufacturers make buckets, although not adhering to some clear standard capacity, which is the same for everyone, but observing common sense, they choose one of the volume options. All options can be reduced to a small “grid” of capacity options and for each indicate a ratio with a volume of 1 cubic meter. We examined in table 1 all possible capacity options, except for the very exotic ones. We got the following displacement: 6, 8, 10, 12 and 14 liters. I think that your bucket, with which you want to measure 1 cube of concrete, is necessarily in our table and you can find out the number of buckets in a cube of concrete. If your option is not in the table, we recommend that you do the calculation yourself, based on the number of liters in 1 cubic meter and the volume of your custom bucket.
Table 1. How many buckets in a cube of concrete, how many buckets in 1 m3, in 1 cubic meter, in 1 meter cubic. To answer the question, how many buckets are in the concrete cube in the table, they are considered with the indication of the capacity quantity of several container volume options. For example: 6, 8, 10, 12, 14 liters in capacity.
In the production of concrete and mortar, automated components mixing plants are used. Each type of component, before getting into the concrete mixer, is dosed in kilograms. The consumption rate of materials is made by the production technologist, who later guides the operator of the BRU.
If you decide to purchase a ready-mixed concrete mix from the manufacturer, then you can not worry about the quality of the material. A responsible company produces products according to GOST requirements, confirming with quality certificates. But, if for some reason you decide to independently replace the concrete mix using a compact concrete mixer, then you will be interested to know how many kg of cement in a bucket, sand, coarse aggregate.
Bulk density of cement and other components
When working, use the same bucket volume. To determine the weight of the material in the tank, you need to know the bulk density of each component. This indicator is indicated in the quality certificate, or on the bag when purchasing packaged material.
Suppose the average bulk density of cement is 1200 kg / cm³, therefore, we multiply this figure by the volume of the bucket in liters. For example, 1200 x 10 \u003d 12 kg weighs a 10 liter bucket.
We make the same calculation with other components. The bulk density of sand is an average of 1400 kg / cm³, which means a 10-liter bucket of sand weighs 14 kg. The bulk density of coarse aggregate is 1500 kg / cm³, therefore, a bucket of material weighs 15 kg.
Now finding out how much in a 10 liter bucket kg of cement, sand, gravel or gravel, you can calculate on a concrete mixer.
Example of calculating cement per bucket
For example, it is required to make 100 liters of concrete mix M200. The most commonly used materials are: Portland cement M400 - 26-30 kg, medium sand - 70-80 kg; coarse aggregate - 100-120 kg. The amount of water depends on the degree of moisture inert materials: the rawer the bulk material, the less water is required.
First of all, all dry components are mixed. After dry kneading, water is gradually added. If concreting occurs when low temperaturethen the water should be warm. It is also advisable to use an anti-frost additive for concrete, which requires 2-3 percent of the amount of cement. The additive is pre-diluted in warm water. After adding it, the concrete mixture should be thoroughly mixed until a homogeneous composition.
The consistency of the concrete mixture should not be too liquid or dry. If you take a part of the material in the palm of your hand and squeeze it, then when you unclench your hand, the mixture should not remain a tight piece, and at the same time should not spread too much on the palm.
Concrete component ratio
It is convenient for some private developers to use not such a consumption of materials, in which it is required to know how many kg of cement in a bucket, but one that is calculated in parts. For example, the following proportions of the concrete composition are applied for mixing the brand 200 concrete mix - 1: 3: 5, i.e. cement: medium sand: coarse aggregate.
But since the components can have different bulk density, it is not recommended to use the latter method, otherwise, when mixing, the structure of the mixture may be violated, which will entail a decrease in the strength of the product.
