Building

For self-construction of a house, many people choose material that is relatively young in terms of appearance on the domestic market - aerated concrete. Made from sand, lime, cement and mineral aggregate without any harmful impurities, aerated concrete is an environmentally friendly material. This is not his only merit; he also has ease and accessibility in processing, which favorably affects the working process.

Parameters of aerated concrete blocks

Всякое строительство начинается с проектирования, в ходе которого ведутся расчеты потребности в основных строительных материалах, в том числе кладочных. В случае с газобетоном эти расчеты довольно несложные (см.также статью «Пылесос для бетонной пыли – характеристики и выбор»).

In order to calculate the amount of material sufficient for the construction of walls, you need to know:

Parameters of the building being constructed.
Geometrical dimensions of the concrete element.

Note! Since the sale of aerated concrete blocks, as a rule, operate with a unit of measurement of volume - a cubic meter, all calculations are immediately more convenient to carry out in meters.

The following sections will describe the detailed instructions for performing the necessary calculations that will help you purchase the right amount of building materials.

Calculation of the volume of one unit

In order to calculate how much in a cube of aerated concrete blocks we will examine the typical sizes of the products.

In the domestic market there are masonry stones with sizes:

100 * 625 * 250 mm.
200 * 625 * 250 mm.
300 * 625 * 250 mm.
400 * 625 * 250 mm.

Here, 625 mm is the standard length of the product, 250 is the height, and figures from 100 to 400 mm are thickness. Of course, you need to understand that in most cases blocks no less than 40 cm thick are used to build the outer walls of the house, when more compact products can be used for internal partitions.

Для наглядности, расчет объема одного изделия выполним на примере кладочного элемента с размерами 400 * 625 * 250 mm.

First, we learn the volume of a piece of aerated concrete by simply multiplying three linear dimensions: 0.4 x 0.625 x 0.25 = 0.0625 m3 1 block.
Now, dividing the unit by the value obtained, we learn how many cubic aerated concrete are in cubes: 1 / 0.0625 = 16 pcs.

Note! You must understand that the number of units will depend on the dimensions of the product. Therefore, before calculating how much aerated concrete in 1 cubic should be determined with the size of the building material. And do not forget about 5-10% surplus, which are added to the total.

Calculation of one wall

We now proceed to the calculation of the volume of one wall of the projected building.

Take, for example, the calculation of the partition with the parameters:

Be sure to prepare a small project on which you can visually record the dimensions of the building.

Length - 8 m
Height - 4m
Thickness - 400 mm.

A simplified calculation of one wall looks like this: 0, 4 x 8 x 4 = 12.8 m3.

Further, there is nothing easier than to calculate the required number of aerated concrete blocks with dimensions of 400 * 625 * 250 mm for masonry of our wall. We multiply the volume of the wall (12.8 m3) by the number of masonry blocks in one cube: 12.8 x 16 = 200 pieces, just as many aerated concrete elements will be needed to build a blank wall of a given size.

Tip! When calculating the number of blocks for the construction of enclosing structures of a real house, all the planned openings should be subtracted from the total volume of the walls: door, window and arched. When building a large and possibly two or more storied building, this can be a rather tangible figure.

And even though the price for this material is not high, the surplus will introduce you to unnecessary costs of the construction budget.

The cost of aerated concrete blocks

If we are talking about the financial part of construction, it is worth noting that the cost of one masonry element is also simply calculated on the basis of the cost of one meter of cubic aerated concrete. And on the contrary, having data on the cost of one element it is easy to find out how much a cube of aerated concrete costs.

For example, one cubic meter of blocks with typical dimensions of 100 * 625 * 250 mm costs 2900 rubles.

We calculate the cost of each element:

We calculate the volume of the masonry unit: 0.1 x 0.625 x 0.25 = 0.016625 m3.
Find out the number of stones in m3: 1 / 0,015625 = 64 pcs.
Based on all the necessary data, we determine what the price of one block will be: 2900/64 = 45.3125 rubles. We round and get - one element with dimensions of 100 * 625 * 250 mm costs 45.32 rubles. This is the average estimated cost.

Products should be purchased only from reliable suppliers that will not hide cracked and cracked products in the center of the pallet.

Note! The total amount of material that you decide to order will significantly affect the final cost of the goods. The place of production of blocks also matters.

Mass of aerated concrete products

When calculating the foundation you need to know the load to which it will be exposed. Therefore, it is important to know how much a cube of aerated concrete weighs.

The weight of aerated concrete depends on the fillers used, based on this, four groups of building material are distinguished:

Lightweight concrete, very porous, weighs about 500 kg / m3.
Lungs with a filler from a shell rock, expanded clay with a specific weight from 500 to 1800 kg.
Heavy with aggregates of gravel and rubble with a weight of 1800-2500 kg.
Particularly heavy weighs 2.5-3 tons. The bulk of this mixture consists of large aggregates.

For ease of handling and transportation, masonry materials are packed on pallets. The answer to the question of how many cubes of aerated concrete in a pallet is simple - in a standard pallet one meter cubic material, but the number of pieces of products on a pallet depends on their dimensions.

Knowing the calculation formulas, you will be able to determine the required number of pallets for construction.

Conclusion

As you can see, a preliminary calculation of building materials allows you to bypass many pitfalls, such as purchasing surplus or double shipping charges. This is especially important if the work is planned to be done by hand, so to speak, in a tight budget, where a dozen extra blocks will violate all plans.
