Geopolymer concrete is being introduced to reduce the rapid utilization of Portland cement concrete. Geopolymer is an inorganic polymer synthesized from alkaline activation of various alumino-silicate based wastes like fly ash, blast furnace slag etc. Geopolymer concrete is presently limited to the pre-cast member due to the requirement of heat activation after casting. Addition of colloidal nano-silica in geopolymer mortar/concrete cured at normal temperature shows an appreciable improvement in strength and durability. To establish structural behaviors of such concrete a series of tests such ...
