A house built from aerated concrete blocks is a durable, inexpensive and comfortable home. However, before starting construction, it is necessary to purchase the necessary materials. The article will consider in detail the process of calculating aerated concrete, taking into account the many technical parameters of the specified building material.
Advantages of aerated concrete
Before starting the construction of a building, it is necessary to find out the advantages of the material from which it will be built. Aerated concrete is a lightweight and reliable artificial stone, which is increasingly used in the construction of various facilities. It is used for the construction of cottages, garages, sheds and other non-industrial facilities. If you need to build a one-story house in a summer cottage, then aerated concrete is an ideal choice due to its low cost and high technical qualities. The advantages of the material include:
- durability;
- flammability;
- reliability;
- lowthermal conductivity;
- calculation of aerated concrete is done using a simple technique;
- high soundproof properties;
- material is protected from the negative effects of fungus and mold;
- sustainable;
- high strength data;
- Aerated concrete is easy to saw and cut with a grinder or other construction tools;
- correct shape and exact dimensions.
If the technical conditions were met during construction, then the result will be smooth and rough walls that can be immediately plastered without additional processing.
Before you purchase projects of one-story houses made of aerated concrete, you must correctly calculate the amount of material. The minimum price of such a document in the construction market is 13,000 rubles, so it is worth planning financial expenses with this fact in mind.
Calculation technique: general information
This technique is suitable for all types of buildings. In this case, the calculation will be made for a one-story house measuring 7 x 8 m, the height of which is 3 m.
There are two techniques for calculating aerated concrete:
- In cubic meters (m3).
- Pieces (pieces)
First of all, you should check with the seller in which units the material is sold. As a rule, large construction companies calculate in cubic meters, since in this way it is easier for the buyer to calculate the cost of the work. The building will be constructed from blocks with dimensions of 30 x 20 x 60 cm: this is the most optimalbuilding material for the construction of a residential building.
But first you need to find out the total area of openings (door and window). For example, the following indicators will be given:
- Two doors measuring 0.8 x 2 m. To find out their area, you need to multiply 0.8 by 2. As a result, you get 1.6 m2. Now the resulting indicator must be multiplied by the total number of doors: 1.6 × 3=4.8 m2.
- Six window openings, each of which has dimensions of 1.5 x 1 m. Performing similar arithmetic operations, we get 9 m2.
Next, you need to add the obtained indicators: 4, 8 + 9=13, 8 m2.
Calculation of aerated concrete for external walls in cubic meters
If the previous mathematical operations were performed correctly, you can proceed to further actions in this sequence.
- Calculate the perimeter of the outer walls of the house - for this you need to add 7 and 8, and multiply the result by 2. As a result, you get 30 m.
- Determine the area of the walls, taking into account their height: 30 × 3=90 m2.
- From the result obtained, it is necessary to subtract the total quadrature of the openings as follows: 90 - 13, 8=76, 2 m2
- The final step is to multiply the resulting figure by 0.3 (this number directly depends on the thickness of the aerated concrete). The result is 22.86 m3.
Thus, for the construction of the outer walls of a house with dimensions of 7 x 8 m, approximately 22.86 cubic meters of aerated concrete will be needed (it is recommended to round the figure to the nearest integer). To find outthis number is for buildings with other dimensions, you just need to substitute the design values in the arithmetic examples above.
It should be noted here that there are recommendations for the thickness of the blocks for each individual case:
- in cold regions, builders build buildings from materials with a minimum thickness of 0.375 m;
- for a single-layer wall, the mentioned indicator is 0.3 m;
- if you plan to build a summer house for a summer cottage, you can use gas blocks with a thickness of 0.25 m.
If the question arises, how many aerated concrete blocks are in the pallet, then this figure depends on the size of the building material. So, for example, with dimensions of 0.3 x 0.2 x 0.6 m, there are 50 pieces of products on one pallet, which is 1.8 cubic meters. In this case, 12.7 pallets are needed to build a house (22.86 / 1.8=12.7 pcs.). It is recommended to round the resulting number up to 13, since a small supply of materials is better than a lack of them.
Below is an illustrative table with which you can set the number of pallets.
| Size (cm) | Volume of one block (m3) | Number of cubic meters in one pallet (m3) | Number of items per pallet (pieces) |
| 0, 75 x 20 x 60 | 0, 009 | 1, 89 | 210 |
| 10 x 20 x 60 | 0, 012 | 1, 92 | 160 |
| 25 x 20 x 60 | 0, 030 | 1, 8 | 60 |
| 30 x 20 x 60 | 0, 036 | 1, 8 | 50 |
| 37, 5 x 20 x 60 | 0, 045 | 1, 8 | 40 |
| 40 x 20 x 60 | 0, 048 | 1, 68 | 35 |
| 30 x 25 x 60 | 0, 036 | 1, 728 | 48 |
| 36, 5 x 25 x 60 | 0, 055 | 1, 752 | 32 |
Calculation of aerated concrete in pieces
In this case, there is one caveat: you need to calculate the volume of one block. During the construction of a country house, material will be used, the thickness, height and length of which, respectively, are 0.3 x 0.2 x 0.6 m. If you multiply the indicated dimensions, the result will be that the volume of one gas block is 0.036 m3.
To find out how many blocks are needed to build a building with dimensions of 7 x 8 m, for this you need to solve the following mathematical example (the indicators were calculated earlier):
22, 86 / 0, 036=635 pieces The first number is the required number of blocks in cubic meters, and the second is the volume of one unit of aerated concrete.
You need to buy 635 pieces of items if you plan to build the indicated house.
It should be said: construction companies sell projects of one-story houses made of aerated concrete. Their price varies from 13,000 to 70,000 rubles.
In conclusion
The article gave a simple example of the calculation of aerated concrete. The indicators depend on the dimensions of the building being erected and the material from which it iswill be built. In construction, there are many types of aerated concrete blocks, each of which is designed for a specific type of structure.
