EXPLOITATION OF SOLID WASTES IN FOAMED CONCRETE: CHALLENGES AHEAD

This paper reviews the contribution of some researchers on blended cement and reports recent findings of a research programme focused on the exploitation of solid wastes in foamed concrete. Solid wastes studied include rice husk and its derivatives, paper sludge and recycled expanded polystyrene (EPS). The objective is to develop an environmental-friendly and economical foamed concrete for construction. A novel process for the synthesis of micronised silica for use in foamed concrete is revealed in order to provide a unique solution to construction on soft soil. Concerted collaborative effort by researchers and the readymix concrete industry is expected to enhance the competitive edge of the construction industry.
