Department of Chemistry, Tangshan Teachers College, Tangshan 063000, China; 2. Tangshan No.2 High school, Tangshan 063000, China) Abstract: Animal protein foaming agent is prepared by the combination mode of surfactant physical foaming and mineral materials physics of foam. And foam concrete is gotten by a separate mixed slurry bubble preparation of foaming agent. The best blowing agent incorporation is assured by investigating the effect of blowing agent incorporation on dry bulk density, compressive strength and water absorption. The experimental result shows that the dry bulk density of the foam concrete was 700 kg·m-3, the compressive strength is 4 MPa, the water absorption is 23% when blowing agent incorporation is 1,150 mL.
