How much does a bucket of cement weigh?


Farming

The main goal of farmers involved in growing grain crops is to obtain maximum yields. When carrying out such work, it is necessary to take into account the climatic conditions of a particular region, the mechanical composition of the soil and the presence of nutrients in it. Many farmers do not know how much wheat weighs, but the weight of an individual grain will depend not only on all of the above influencing factors, but also on the variety used. In practice, when carrying out calculations, the weight of a troy grain (average value) is used. This figure is equated to 0.65 grams.

Many farmers are interested in how much a cube of wheat weighs, especially if the grain is stored in a barn and its volume can be easily calculated without additional weighing. Here you can carry out simple calculations, for example, thaw a liter glass jar, pour wheat into this container and weigh it again. After carrying out such work, you can find out that 700-800 grams of grain will fit in a liter jar.

From the mathematics course we know that one cube contains 1000 liters, which means that 700-800 kilograms of wheat will fit in the described unit of volume. Such a significant discrepancy in weight can be associated not only with the characteristics of the variety, but also with the moisture content of the grain.

Now many agricultural workers buy grain by the bucket, rather than by weight. In this case, unscrupulous sellers can deceive their buyers. In order not to fall for such a trick, everyone should know how much a bucket of wheat weighs, and also be able to carry out the necessary calculations to calculate their own benefit. Let’s say a 10-liter bucket of grain costs 100 rubles, while a kilogram of the same product is sold for 10 rubles. We know that one liter contains 700-800 grams of grain, respectively, 7-8 kilograms will fit in a 10 liter bucket, but not 10 kg, so in this case it is better to buy by weight.

Values ​​of specific and volumetric weight of construction sand

Today, sand is one of the most common building materials. This is the main element of construction. Its purchase must be approached competently in order to know what amount of sand to take into account when purchasing and preparing mortars and concrete.

When using sands for concrete, we may be interested in

  • specific gravity of sand
  • volumetric weight of sand,
  • strength of sand grains,
  • the nature of their surface,
  • grain shape,
  • possible resistance of sands (depending on the mineralogical composition),
  • coefficients of linear and volumetric expansion,
  • hardness
  • and abrasion (wearability) of grains, etc.

When designing the composition of concrete, it is necessary to know

The specific gravity of sand or specific gravity is the weight that fits in a unit volume. It is defined as the ratio of the mass of sand in a dry state and its occupied volume. In most cases, a volume of 1 cubic meter is used for sand.

This variable value can range from 2.55 to 2.65 units and differs for sand of different origins.

The volumetric bulk density of sand is widely used in its reception and transportation.

The volumetric weight of construction sand is a unit of volume in the natural state of the sand (with impurities, moisture).

Volumetric and specific gravity may differ, so during construction it is necessary to take into account all errors.

On average, the volumetric weight of sand is 1 cubic meter. m is 1500-1800 kg. According to GOST 8736-77 standards in 1 cubic meter. m contains 1.6 t.

In tables and reference books, the specific gravity of construction sand is indicated in grams per 1 cm³, kg m³ or in tons per m³.

The specific gravity of sand depends on the content of grains of various minerals in its mass, the specific gravities of which, according to P. I. Fadeev, are given in Table.

The last properties of sands have been most fully revealed. Thus, the specific gravity of quartz sands of alluvial origin (river sands) varies within small limits, usually from 2.64 to 2.70, averaging 2.66 in the absence of organic impurities (according to P.I. Fadeev).

According to his data, the specific gravity of aeolian sand in Western Kazakhstan is 2.71, and in the Astrakhan region - 2.74;

the specific gravity of sea sand in the Black Sea is 2.63, and in the Azov Sea - 2.78.

You can buy in bags and cubes, as well as in tons. Quartz sand is sold in bulk (carloads, machine quantities) and in packaging. Packaging can be very diverse: today the market offers containers from 2-4 kg to 1,500 liters.

For construction work in low-rise and private construction, a table of specific gravities not only in m3, but also in buckets will be convenient. It is always possible to more accurately indicate to workers how much of which materials to mix and in what proportions.

Video of the specific gravities of dry, wet, compacted, loose sand.

Since the specific gravity of sand changes almost insignificantly, the main influence on the volumetric weight of sand is its voidness.
