Calculation of concrete on the foundation: how to implement

The construction of any type of buildings and most of the buildings requires the construction of a foundation for them. In this case, the developer can choose from two options - to prepare a solution for the base on its own or order it at the nearest concrete plant.

It does not matter which of these methods you choose, you first need to calculate the amount of concrete on the foundation. Implement it quite easily. When calculating, standard mathematical formulas will help you.

Calculation of the volume of the mixture under different types of foundations

To calculate the amount of concrete for the foundation, it is necessary to take into account its type.

Tape base

1. This type is a continuous tape at the base of the external and often internal walls.. Laying it under the bearing structures of the building makes it possible to distribute the mass of the building around the perimeter.
2. This allows the base to resist the swelling of the earth in winter and stops the building from tilting.. Paving the necessary communications in such a base helps diamond drilling holes in concrete.
3. They build their own hands on similar bases, such as light wood, frame, panel board, and rather heavy brick and concrete houses in one or two floors. The main advantage of the tape counterpart to a monolithic slab base is a lower price due to the significant savings in concrete mix and reinforcement.
4. Based on the degree of heaving and bearing capacity of the soil, the belt structures are constructed deeply or shallowly deep..
5. This type of construction makes it possible to build a basement or concrete basement..

To calculate the amount of concrete for a tape-type foundation, the formula is applied: О = 2ШВ • (Д1 + Д2).

The letters in it mean:

• W-width of the structure;
• B - the height of the structure;
• D1 is the length of its outer side;
• D2-similar parameter of the inner side.

Plate analog

Before you make the calculation of concrete for the foundation of this type, it is necessary to consider that this is a solid (monolithic) slab under the whole building.

Note! This type of foundation is considered the most reliable by specialists. The instruction recommends choosing them if the soil at the construction site is problematic. The plate distributes pressure loads from the ground at the entrance of its heaving over its entire surface. Due to this, at first the structure rises a little, and then falls back, because of its large mass.

On such structures most often built heavy brick, stone, concrete buildings on one or several floors.

1. The calculation of concrete cubes on the foundation in this case is carried out according to the formula: O = D1 • D2 • V.
2. Here D1 and D2 are the lengths of the sides of the structure, and B is the height of the slab.

Column type

1. He represents the pillars. They are placed in the corners of the future construction, at the points of intersection of the walls and partitions, in addition - in areas with the highest loads (log frames, supporting structures, etc.).
2. Such a construction is best suited for light and small buildings of logs, lumber, shields.
3. Such a structure is the most economical.

To calculate the cubic capacity of concrete for a columnar foundation, the following formula is used: O = (3.14 • D2: 4) • B. The letters here mean: D - diameter of the pillar, B - its height.

Calculation examples

We give specific examples of calculations for all types of foundations.

Calculations for tape type designs

1. Let's say you need to lay a foundation having sides of 6 × 10 meters. Its height is 1.8 meters, and its width is 0.3 meters.
2. We use the above formula: 10 • 3 • 2 + (6-0.3 • 2) • 0.3 • 3 = 11.04 m2.
3. As a result, the required volume of concrete for our strip foundation is: 11.04 • 2 = 22.08 m3.

Calculation of the solution for a monolithic slab base

The calculator for calculating concrete on a slab type foundation is much easier.

1. Let's say you need to build a building base with sides of 5 × 8 meters and having a thickness of 0.4 meters.
2. We multiply all three quantities: 5 • 8 • 4 = 16 m3.

Note! An amendment to the reinforcement cage is not necessarily taken into account. The volume of this design is negligible.

Calculation Example for Column Foundation

The column construction needs more complex calculations.

1. First of all, the volume of the solution is calculated, which is required for one column.
2. Further, the resulting figure is multiplied by the total number of supports.

We give a specific example.

1. The diameter of one leg is 0.25 meters.
2. Its height is 1.5 meters.
3. The total number of concrete pillars is 15 pieces.
4. Apply the formula and find out the amount of concrete needed for a single support: 3.14 • 25 • 0.25: 4 = 0.049 m3.
5. The total cubic capacity of the desired concrete for our column base is: 0.49 • 15 = 0.735 m3.

Based on these data, the obvious conclusion is that the construction of the base of the columnar variety requires a minimum amount of the mixture. In case of need to process supports, reinforced concrete is cut with diamond circles.

Conclusion

Any kind of bottom of the house should be carefully designed. Including, it is necessary to accurately determine the volume of the solution that is needed to fill it. The video in this article will continue its theme.
