Foam concrete machine for underground filling

Foam concrete, also called lightweight concrete, is one kind of popular building material. It possesses high flow ability, low self-weight, minimal consumption of aggregate, controlled low strength and excellent thermal insulation properties. Because of these advantages, it is widely used underground filling, roof, roof insulation, floor heating, CLC block and so on. 

In excavations with poor soils that cannot be easily compacted, foam concrete forms a 100% compacted foundation over the soft sub-soil. Compaction of conventional, granular backfilling against retaining structures or deep foundations can cause damage or movement to the adjacent structure. In these situations, foam concrete with its reduced lateral loading is a safe solution.

Foam concrete as underground filling material, now foam cement machine is widely used in China's subway construction, and achieved good effect. Besides,  foam cement foaming machine reduced the project cost very much.
