Foam concrete is usually use mechanical methods foaming agent solution preparation into foam, and will be added to the foam with siliceous materials, calcareous materials Mobile Placing Boom, water and various kinds of additive, etc of the slurry, the hybrid mixing, pouring forming ball mill manufacturers, curing and become a kind of porous material. Because foam concrete contains a lot of closed pore, make its have the following good physical and mechanical performance.

Foam concrete density is small, the density level general for 300-1800 kg/m3, commonly used foam concrete density level for 300-1200 kg/m3, in recent years, density for 160 kg/m3 of super light foam concrete in construction engineering for the application. Due to the density of the foam concrete small, in building inside and outside wall, level, floor Continuous concrete batching plant, column, etc in the building structure by the material, general can make the structure weight reduced by 25% or so, some can reach structure total weight 30% - 40%. And, in terms of structures, such as using foam concrete to replace the ordinary concrete, can improve the member's bearing cutting ability. Therefore, in the construction project with foam concrete has significant economic benefits.
2, thermal insulation performance is good
Because foam concrete contains a lot of closed small pore, so has good thermal performance, i.e., good thermal insulation performance, this is common concrete does not have. Usually density level in 300-1200 kg/m3 range of YT foam concrete, coefficient of thermal conductivity in the 0.08-0.3 w/(m. K), thermal resistance between about common concrete 10 - twenty times. The foam concrete as building walls and roofing material, have good energy saving effect.
