We use the calculator - we consider the estimate for the construction of a private house from foam blocks
You need to be able to correctly determine your financial costs so that you do not have to overpay for unnecessary and additional services of construction organizations. You just use the calculator for building a house from foam blocks and get data close to real. In accordance with the results obtained, you invest in the construction of the facility.
Estimate for a standard foam block house. Foundation
If you plan to build a house from a foam concrete block with dimensions of 6 by 8 meters, and there is a terrace and 3 living quarters. There is also a kitchen in the building. It is necessary to build a box from , but before that, carry out a number of important calculations.
Suitable as a foundation for such a structure, but at the same time it is necessary to choose the right depth of penetration, depending on the characteristics of the soil and the parameters of the building.
Since foam concrete blocks are a building material with low weight, a depth of up to 0.5 meters is allowed, provided that we are dealing with sandy or clay soil. If you make a deeper strip foundation, then there is an opportunity for a basement or cellar.
By design, the foundation for an object made of foam concrete blocks can be:
- buried
- Shallow,
- Monolithic
- Teams.
The most reliable design is a monolithic type, so you should choose it. And the cost of materials for the foundation must be included in the total cost of. Basically, a large amount of cement and sand, as well as crushed stone, will be required.
The overall dimensions of the strip foundation are 200x300x600 mm, while it must be taken into account that the basement will be connected to the formwork to ensure the solidity of the structure. The height of the tape together with the base part is 1 meter. To calculate the length of the foundation, you need to add up all the lengths of the dug trench.
Now it remains to sum up and calculate the volume of concrete mixture that will be poured into the formwork: 50 (trench length) × 1m (height) × 0.5 (depth) = 25 cubic meters. For such purposes, high-quality concrete is used. One cubic meter of foundation should contain:
- 385 kg of cement,
- 220 liters of water,
- 700 kg of sand,
- 1000 rubble.
With these figures at your disposal, the total amount of materials and the cost of the entire foundation are easily calculated. You just need to take into account the reinforcement and enter data into the calculator for building a house from foam blocks about the reinforcement used.
Before the floor is poured, a similar calculation of the concrete mixture is made, as in the case of the foundation.
Number of foam concrete blocks for walls
Practically in any house there are load-bearing walls and interior partitions, and they differ in design features. If it is recommended to use half-brick masonry for load-bearing walls made of foam block, then a quarter will be sufficient for partitions. The side part of the foam concrete block is 200 × 300 = 0.06 meters, the bed is 300 × 600 = 0.18 meters.
Before using the calculator for building a house from foam blocks, you need to decide on the height of the walls, which can be 2.8 meters or higher. For a height of 2.8 meters, foam blocks in the amount of 14 pieces will be required, while the seams are 0.5 cm. This means that, taking into account the fact that the laying of the bearing walls is made in half a brick, we get 2.87 m.
The room usually includes floor and ceiling coverings that take up usable area, so the height can change downward. The area of bearing walls is calculated using the expression (8 + 8 + 7.3 + 6 + 4 + 1.3) × 2.8 = 96.88 square meters. And if this value is multiplied by the area of the foam concrete block, then the amount of 1615 stones is obtained.
Knowing the number of partitions and their height, the area is easily calculated: (8 + 3 + 3) × 2.8 = 39.2 square meters. Now you need to multiply this result by the area of a quarter of a brick and you get 218 stones.
In the calculator for building a house from foam blocks, data must be entered on the amount of special glue that will be required for both external and internal walls.
For these purposes, you need to use the length of all the walls and find out how many seams you get, both in the horizontal and vertical directions. The thickness of the adhesive layer is usually 0.005m.
