The research presented in this paper is aimed at developing novel alternative sustainable stabilized earth materials for use in load-bearing affordable housing construction. Prototype-stabilized earth materials have been produced in the laboratory, incorporating a range of solid wastes, including aggregates derived from construction and demolition waste as well as industrial processes. The earth construction materials were stabilized with either portland cement, Portland cement and lime, or through alkali activation. Experimental results for compressive strength are reported, together with findings from a comparative life cycle inventory analysis. Construction and demolition waste shows promise as a potential aggregate for stabilized earth construction. The use of processed ground blast furnace slag together with fly ash is also promising for the development of alkali-activated stabilization.
