The main component of any building is its floor, which forms the major area of a building. The floor is the most important part of any structure due to traffic, transfer, storage and transfer. The operation of making the floor of an area usable is called flooring.
Concrete is a composite material that is mainly composed of Portland cement, water and aggregate (sand, sand or stone). When these ingredients are mixed together, they form a workable paste that then hardens over time. Concrete is an important construction material that is widely used for building floors, bridges, roads and dams. Concrete floors are useful in terms of strength, fire resistance, acoustics, maintenance and longevity. In the following, the definition of concrete flooring, its advantages and disadvantages, as well as the types of concrete flooring are discussed.
If flooring is done with concrete, it is called concrete flooring, which is done in different ways. One of the most important stages of concrete flooring is joinery in the floor area of any structure. This operation is used in high-traffic buildings because the pressure exerted on the surface is very high. For example, it is useful for parking lots, shopping centers, meeting halls, factory floors and other public places. An important point to consider in the concrete floor implementation stage is to comply with the necessary standards. Because if they are not followed, problems will occur over time that will have negative effects, such as creating cracks in the concrete floor, the appearance of uneven surfaces, lack of resistance to pressure, fire, etc. Therefore, in addition to observing the principles in concrete flooring, it is necessary to use high-quality concrete to avoid problems.
In general, to perform concrete flooring, several layers of mortar must first be poured on the desired surface. In the next step, the floor of the structure is leveled using filling materials such as soil or pumice and sand to prepare for flooring. At the last stage, concrete is poured and floor construction is carried out. Of course, you should keep in mind that concrete flooring is done in this way in all projects, for example, in areas where there is heavy snow and rain, insulation is also done on the surface. Although the conditions of each project are different from each other, the general process for implementing concrete flooring is as follows:
🔶 Advantages of using concrete foam 🔶
As one of the newest materials that can be used in the country's construction industry, foam concrete is also very popular, and the reason for this popularity can be found in the following features.
1. Proper sound and thermal insulation
Concrete foam is an excellent thermal insulation due to its porosity and having a unified texture, which will increase significantly with the reduction of concrete density. Concrete foam has the ability to insulate against cold and heat, and in addition to this, it is considered as one of the suitable sound insulators, especially in multi-story buildings. 2. An effective moisture insulation, since foam concrete has layers with many porous surfaces, it naturally has hair gaps and less seams on the surface, and if the concrete foam cover is used with sufficient thickness, against the penetration of rain and Moisture will show good resistance.
3. High speed in implementation
Using light concrete in the implementation of projects, it is possible to avoid wasting time in the implementation of flooring and achieve the best results in the shortest time. Foam concrete machines can produce 60 to 90 cubic meters of concrete daily, which means that the speed of implementing foam concrete is about 7 times higher than the traditional method. We can make about 560 square meters of concrete at the same time.

4. Cheaper than traditional concrete
One of the most important reasons for choosing foam concrete by employers is its low price compared to traditional concrete because foam concrete is cheaper.
5. High compressive strength Compressive strength is an important parameter in the construction industry because it shows the ability to withstand pressure and load on the surface; Therefore, at present, the favorable compressive and tensile strength of foam concrete has led to the use of some types of foam concrete in many advanced countries, in addition to construction, even in the flooring of roads and road foundations. In fact, the presence of high compressive strength in this type of concrete is associated with an almost unlimited increase in strength.
6. Fire resistance
Foam concrete does not catch fire and by adding thickness or reducing its density, resistance can be created to a great extent. For example, a piece of foam concrete with a specific weight of 700 to 800 kg/m3, which is at least 8 cm thick, can withstand heat up to 1270 degrees Celsius, which is much more efficient than conventional or traditional concrete. .
7. Low weight
Foam concrete has a light weight of about 400 to 1700 kg per cubic meter, and this issue can be a factor in reducing the weight of the entire constructed structure.
8. Eliminating environmental stress in general, in construction operations, carrying materials, pumice, workers' movement and using different tools greatly increases the possibility of damaging the building's floor facilities. At the same time, we must state that the implementation of foam concrete is transferred to the floors through a pump, and there is no need for any transportation and, of course, no damage. Also, due to its fluidity and small bubbles, foam concrete can be used as insulation for the building's floor facilities, and there is no need to stretch the building.
