What is the common density of foam concrete?

Foam concrete has lower density and normally it is 300-1800kg/m3. The common density in our daily life is 300-1200 kg/m3. Because of the lower density, it is widely used as a main material of internal and external wall, roof, floor and columns in various kinds of building. It can reduce the weight of building by about 25%, even it can be 30%-40% of the building in some cases. Therefore, it will bring us remarkable economic benefits once we adopt foam concrete in construction.
