Physicochemical Properties of Alkali Activated Fly Ash Based Geopolymer Concrete:A Review

Geopolymer is a term covering a class of synthetic alumino silicate materials with potential use in a number of areas, essentially as a replacement for Portland cement. Geopolymer is a lower carbon dioxide production emission, greater chemical and thermal resistance with better mechanical properties. In this paper a in depth review on alkali activated geopolymer was made, starting from its evolution till recent development. These technology which uses alkali activated binder instead of cement will emerge as the future. But still lot of studies and research were needed in finding the right way of curing for achieving the desired strength and also the effect of alkalinity on rebars and concrete ages.
