foam concrete

Foam concrete is a type of spumy concrete materials with a great number of tiny, closed and uniform pores.These pores in interior of the materials have a great deal of air ，which degrades largely the thermal conductivity of foam concrete materials.The pores in the materials are closed and disconnected to each other so that convective circulation cannot be formed. Meanwhile, the concrete is separated inside by pores, which, of spherical shape, are encompassed by cement paste .Generally, foam concrete is mainly used to reduce structure’ own weight or good heat and sound insulation fields.
