foam concrete Product performance and characteristics of

Foam concrete is made of foam agent by physical method, and then the foam is added to cement The slurry made of aggregates, admixtures, admixtures and water is mixed, poured, shaped and cured to form lightweight microporous concrete.

Features of foam concrete:

1. Light weight and high strength

The density of foam concrete is small. The density grade of commonly used foam concrete is 200-1200Kg/m3, which is equivalent to 1/2-1/10 of ordinary concrete. The compressive strength is usually between 0.2-7.5Mpa. Foam concrete products with different strengths can be produced according to the design requirements of buildings. On the roof, floor wall The use of this material in non bearing parts such as up turn beam filling and foundation pit filling can significantly reduce the dead weight of buildings and improve the bearing capacity of components.

2. Thermal insulation

The foamed concrete has good thermal performance because it contains a large number of closed small and independent spherical pores. The thermal conductivity of foam concrete with density grade of 200-1200Kg/m3 is 0.06-0.3w/(m.k), which is applied to building roofs, floors, and non load bearing filling materials, with good thermal insulation and energy saving effects.

3. Good sound insulation performance

Foam concrete is a porous material. According to the impact sound insulation standard in GBJ118-88 [Code for Design of Sound Insulation of Civil Buildings], the impact sound insulation performance of MD foam concrete floating floor has reached the second and third level standards for residential, hospital and hotel buildings, and the third level standards for school construction sites. It has good sound insulation performance Sound insulation board , the top floor of underground buildings and other fields can use this material as a sound insulation layer.

4. Low elasticity and earthquake resistance

The porosity of foamed lightweight concrete makes it have a lower elastic modulus, which makes it have a good absorption and dispersion effect on impact load. The lightweight nature of foamed concrete can effectively reduce the load of buildings by 20% - 40%. The smaller the load, the stronger the seismic capacity.

5. Safe, fireproof and durable

Foam concrete is made of the same material as the base course of the building, with good wind pressure resistance, impact resistance and weather resistance. Foam concrete is an inorganic incombustible material, whether used for roof insulation or indoor Floor heating The insulation cushion does not need to worry about fire prevention. Foam concrete is Cement products It has stable performance, long service life, and a shelf life of more than 50 years, which is basically the same as the service life of the main building.

6. Easy production and fast construction

Foam concrete is produced and pumped by * * foam concrete production equipment during on-site construction, and can be poured directly on the construction face, saving labor and time.
