Abstract:
Three proportions of municipal solid waste incineration(MSWI) bottom ash (abbreviated as slag) mixed with sand were used as fine aggregate to make concretes with strength grades of C20, C30, C40, and C50.Workability and strength development were evaluated. Experimental results show that appropriate proportions of slag mixed sand could be used as fine aggregate in medium and low-strength concrete. The proportion of 5:5 slag mixed sand can be used to prepare concrete from grades C20 to C50; the proportion of 6:4 slag mixed sand can be used to prepare concrete from grades C20 to C40; and grades C20 and C30 concrete can be prepared by using the proportion of the 7:3 slag mixed sand. In the range of C20 to C50, the cost of the raw materials for concrete that is made using slag mixed sand is lower equal to the cost for concrete made with river sand. Thus, the former has economic and environmental advantages. It is concluded that the 5:5 slag mixed sand is the optimum proportion.
