Alkali silica reaction (ASR) is one of the major problems with the aggregates. Volumetric expansion of silica gel produce internal stresses in the concrete and leads to strength loss, cracking and failure of the structure. In the present investigation three different types of aggregates were used with Fly ash and GGBS based Geopolymer as binder.
