Abstract : Alkali activation of earthen mixture capable of self-consolidation was investigated. Influential factors such as the concentration of activator, additive substitution, and the curing process are studied, keeping the mix workable. A reliable mix proportion with 75% dry weight as soil and 25% dry weight as fly ash (both class C and class F types) with an optimized curing temperature and duration is achieved. The role of curing temperature and duration in strength development is studied and optimum value is obtained. These mixes were then added with a minor proportion of OPC, and its response to two curing methods, viz., moist curing and ambient curing, is also investigated. The end products are microstructurally studied through SEM and XRD.
