And the low density foamed cement preparation

The present invention discloses a low-density foam cement, comprising the following parts by weight of components: 60 to 120 parts of cement, 0.3 to 1.0 parts by coagulants, 0.4 to 1.0 parts foam stabilizer, 0.5 to 1.2 parts superplasticizer, 9 to 14 parts foaming agent, 0.2 to 0.5 parts fiber, 25 to 50 parts of water. The present invention also discloses a method for preparing the low-density foam cement. The low density foam concrete is stirred uniformly by a dry powder, a cement slurry made by adding water, add a blowing agent with rapid stirring, pouring molding, curing and other steps can be made of natural, dry light weight, low thermal conductivity.
