Design & Development of Geopolymer Concrete

Geopolymer concrete has emerged as a novel construction material and is one of those technologies where research is attempting for the last two decades to replace with OPC. Also it has been established that geopolymer can act as an alternative binder to OPC in the concrete. Apart from its several technical advantages like good physical chemical and mechanical properties geopolymer concrete adds sustainability to the environment as it has significantly smaller greenhouse footprint than Portland cement binders. Geopolymer binders are a class of aluminosilicates based materials. Geopolymers are synthesized by thermal activation of solid aluminosilicate materials such as fly ash (FA) metakaolin rice husk ash (RHA) granulated blast furnace slag (GGBS) etc. with an alkali metal hydroxide and silicate solution.
