Abstract

Due to the high cost of concrete buildings which includes materials, transport and labour, the actual tendency is directed towards finding out solutions for cost effective and durable constructions. a new approach for soil casting was developed. It deals with the production of water resistant building units from casting flowable soil stabilized by binders. Pourable earth is prepared by mixing sandy soil with up to 15% binder and superplasticizer. The binders used are Portland cement, waste glass and thermally activated clays in presence of cement kiln bypass dust. The flowability of the mixes is measured and the compressive strength is recorded. The products obtained present a new method for construction; easy, sustainable, economic and of environmental benefits. The results showed the efficiency of combining sandy soil, glass waste, and activated clay with components of cement kiln dust to produce an environmentally friendly mixture at lower costs, which will contribute to the development of housing units in the desert.
