What is foam concrete? Foam concrete, also known as foamed cement, lightweight concrete, etc., is a new type of building energy-saving material with waste utilization, environmental protection, energy conservation, low cost and non-flammability. Lightweight concrete (foam concrete) is formed by introducing air or nitrogen, carbon dioxide, oxygen and other gases into the concrete slurry through chemical or physical methods according to the application needs. Through reasonable curing and moulding, it contains a large number of small closed pores, The lightweight concrete (foam concrete) is usually made by mechanically preparing foam agent aqueous solution into foam, adding foam to the slurry consisting of siliceous materials, calcareous materials, water and various admixtures, and then mixing, casting, moulding and curing.
Characteristics of foam concrete Foam concrete is usually a porous material made by mechanically preparing foam agent aqueous solution into foam, adding foam to the slurry consisting of siliceous materials, calcareous materials, water and various admixtures, mixing, casting, moulding and curing. Because foam concrete contains many closed pores, it has good physical and mechanical properties. The density of foam concrete is small, and the density grade is generally 300-1800kg/m3. The density grade of commonly used foam concrete is 300-1200 kg/m3. In recent years, ultra-light foam concrete with a density of 160 kg/m3 has also been used in construction projects. Because of the low density of foam concrete, the use of this material in the internal and external walls, floors, columns and other building structures of buildings can generally reduce the self-weight of buildings by about 25%, some up to 30% - 40% of the total weight of structures. Moreover, for structural members, If foam concrete is used instead of ordinary concrete, the bearing capacity of the component can be improved. Therefore, using foam concrete in construction projects has significant economic benefits and good thermal insulation performance. Because foam concrete contains many small closed pores, it has good thermal performance, that is, good thermal insulation performance, which is not available in ordinary concrete. Generally, foam concrete with a density of 300-1200 kg/m3 has a thermal conductivity of 0.08-0.3w/m · K and a thermal resistance of 10-20 times that of ordinary concrete. Foam concrete is used as building wall and roof materials, which has a good energy-saving effect.
Use of foam concrete With its good characteristics, foam concrete is widely used in energy-saving wall materials and has also been applied in other aspects. Currently, the application of foam concrete in China is mainly roof foam concrete insulation layer cast-in-situ, foam concrete blocks, foam concrete lightweight wallboard, and foam concrete compensation foundation. However, making full use of the good characteristics of foam concrete can expand its application field in construction engineering, accelerate the project's progress, improve the project's quality, and use it as a retaining wall. It is mainly used as a rock wall of the port. Foam concrete, used as a lightweight backfill material behind the bank wall, can reduce the vertical cut-off load and the lateral load on the bank wall. This is because foam concrete is a rigid body with good bonding performance. It does not exert lateral pressure on the bank wall along the periphery, so the settlement is reduced, and the maintenance cost is reduced accordingly; Foam concrete can also be used to improve the stability of the embankment slope, replacing part of the soil of the slope with it. Because the quality is reduced, the force affecting the stability of the slope is reduced.
Price of foam concrete Foam concrete particle size and purity will affect the product's price, and the purchase volume can also affect the cost of foam concrete. A large amount of large amount will be lower. The price of foam concrete can be found on our company's official website.
