How to calculate the number of foam blocks for building a house

The construction of any object begins with the preparation of the project and estimates. And if specialists are involved in calculating the required amount of materials in production, then with the independent construction of a private house or other buildings, the developer has to do this himself. How to correctly calculate the number of foam blocks in the construction of a private building from this material? It is not at all difficult to solve such an important task when building a house or an outbuilding, if you know and take into account several important nuances.

Material benefits

Foamed concrete is currently a fairly popular material. It is indispensable where it is impossible to use other types of building materials - brick, stone, wood. Foam blocks are used, depending on their brand, for solving different types of tasks:

1. Building basement levels.
2. The construction of load-bearing internal and external walls.
3. Creating partitions.
4. Masonry contour extra layer.

The reason for such a high popularity of foam concrete blocks is their strengths. It:

1. Environmental cleanliness - sand, cement and foaming agent are used to make blocks.
2. Heat saving properties. The porous structure is an excellent obstacle to cold and heat, thanks to this a stable temperature is maintained in the house.
3. Resistance to chemical mixtures, fire, temperature changes.
4. Light weight, which allows you to use the material for the construction of buildings on unstable soils and not to create heavy powerful foundations under them.
5. Speed ​​of installation. Products are much larger than brick, so the laying of walls will be much faster.
6. Ease of processing. Foam blocks, if necessary, are easily shortened to obtain the element of the desired size. In addition, it is easy to create channels in them to lay pipes, electrical wiring and other communications.

Material counting

To calculate the number of foam blocks for building a house, you must consider the following parameters:

1. The volume of the bearing elements.
2. The area of ​​the building. Specifically - the area of ​​the walls.
3. The number of linear meters.

Since there are no standard indicators for these measurements, therefore, when calculating, you will have to proceed from the dimensions of the building and the blocks themselves.

Foam block products of various sizes are produced. For external walls, blocks of 20 x 30 x 60 cm in size are used. For the construction of load-bearing walls, they are laid on the edge in rows so that the layer is 2 elements thick. Then the wall thickness will be sufficient (40 cm) and will withstand all the loads. If laid out in one layer, the wall thickness will be only 30 cm and this is not enough to maintain the weight of the walls and the roof itself.

Next, it is necessary to calculate the number of foam blocks for internal partitions that are not bearing. For their construction, products with a size of 10 x 30 x 60 cm are suitable.

Features of calculating the required amount of material

In order to correctly and correctly calculate the number of foam blocks, it is necessary to divide the building sections into groups:

1. The first is the supporting external walls.
2. The second - bearing internal walls.
3. The third is internal partitions that do not carry any loads.

When choosing a material, the number of storeys of the future building must be taken into account. For internal piers, on which a small load falls, foam concrete products of the D400 or D500 brand are suitable. For a two-story house, you will need to purchase more durable foam blocks - D600 or D700 brands. If a three-story building is being built, foam blocks of the D800 and D900 brands are needed.

To calculate the number of foam blocks, divide the object into groups, calculate the parameters of each of them. From these indicators calculate the area occupied by windows and doors. Moreover, the doors are both external and internal.

It is imperative to add a certain number of blocks of their foamed concrete to the resulting figure - in case damaged products are caught or a cut is made incorrectly and the block does not fit, you will need to use the following. In other words, a small margin should always be.

Counting Options

There are two ways to calculate the number of foam blocks for construction - in rows and in volume. Each of them has its own advantages. The choice of a specific method is not necessary at all: you can use both and compare the results.

If they match, then everything is calculated correctly, if not, somewhere a mistake has been made and you will need to double-check all the numbers. How to count using each method? About it further.

Quadrature Count

To make it easier to understand how to calculate the number of foam blocks per house, it is best to analyze the features of this action using an example. First, calculate the area of ​​the building. The deduction of window and doorways is done later. To start, the calculation is performed on the first floor:

1. Calculate the perimeter: 8 x 2 + 8 x 2 = 32 m.
2. Divide the resulting figure by the length of the foam block (0.6m). 32 m: 0.6 m = 54 pcs.
3. Calculate how many rows there will be - the floor height (3 m) divided by the block height (0.2): 3.0: 0.2 = 15.
4. Now it remains to multiply the number of blocks of one row by the number of rows: 54 x 15 = 810 pcs.

Now it remains to subtract from the figure obtained those products that will be superfluous due to the presence of windows and doors. Since the initial planned reserve of 8-10%, you can not calculate the openings. But for example, it’s worth calculating. If the total volume of windows on the first floor is 20 square meters. m, this figure is multiplied by 5.56 and get minus 111 pieces of the total. In the same way, the remaining floors are calculated if the building is classical. If you plan to build an attic, the calculation will need to be changed by calculating only triangular gables. To do this, multiply the length of the attic (8 m) by the height (3 m) and divide the resulting figure by 2, you get 12 m: 0.6 m = 20 pieces on one side.

Volume Count

To calculate the number of foam blocks by volume, use the same house size data: height 3 m, perimeter 32 m. After multiplying the data, a volume of 96 m is obtained. Now it remains to multiply this figure by 0.3 - the height of the masonry. It will turn out 28.8 cubic meters. One cubic meter is 27.7 standard foam blocks. Multiplying by the number of required cubes, you can get an indicator of the desired number of products - 798 pieces. This is for the construction of the first floor.

Conclusion

Calculating the number of foam concrete blocks per house is not at all difficult if there is data on all indicators - the area, volume, width and height of the levels, the size of the attic, and the dimensions of the openings. Thanks to the knowledge of all the numbers, you can perfectly accurately calculate how much material is needed. The stock should not exceed 10-12% of the total amount of material. This will allow you to find out the amount of funds required for the purchase of material for construction, and the features of its transportation, storage and storage.

If you do not want to make any calculations, you can use the calculator on any of the construction sites on the Web or contact the design office.
