Character and Development Analysis of Foam Concrete Cooperating Rice Husk Ash

Abstract:

The effect of rice husk ash (RHA) on foam concrete was studied. Firstly, performance and application of foam concrete was introduced in this paper. Secondly the character of RHA was described. RHA contains about 90% amorphous silica, which has high pozzolanic activity. Partial replacement of cement by RHA can enhance the strength of foam concrete in later age and improve durability, homogeneity and corrosion resistance. It also improves the pore structure of foam concrete, thermal insulation and sound absorption performance. Finally, development of foam concrete mixed with RHA was analyzed from following aspects: selecting and processing materials such as foaming agents, RHA and cement; optimizing production process of foam concrete. And since RHA is the major agricultural by-products of rice, it can reduce cost and environmental impact by replacing cement in foam concrete. As an environment friendly material, foam concrete cooperating RHA has great potential in construction field.
