Abstract：In order to make foamed concrete by using the harmful stone powder discharged in artificial aggregate production to reduce the environmental pollution，the test study of stone powder foamed concrete was carried out during the reconstruction of Yushu after earthquake. This paper discusses the optimization of foaming agent，the effect of stone powder on the performance of foamed concrete，the relationship between dry density and compressive strength and water absorption rate，puts forward the mixing ratio of stone powder foamed concrete，and summarizes the basic method of making foamed concrete by stone powder. The research results were successfully applied in the reconstruction of Yushu，which solved the shortage of roof insulation materials at that time，achieved the effect of energy saving，emission reduction and cost reduction.
