Efforts are underway throughout the world to develop an eco-friendly construction materials, which will minimize the utility of fast deteriorating natural resources and also to reduce the emission of green house gases. In this regard, Geopolymer plays a vital role and many researchers examined the various facets of its feasibility as a binder material. Ground Granulated Blast Furnace Slag (GGBS) has been included in the Fly Ash (FA) based Geopolymer Concrete (GPC) to modify the geopolymerisation reaction of FA. In this paper, the influence of the various proportions of GGBS (0-100%) on Fly Ash based GPC; the effect of the amount of Alkaline Activated Solution (AAS) in the mixture of GPC on their compressive strength is studied under ambient temperature conditions. From the experimental results, it was observed that the compressive strength of the GPC is increased with the increase in the percentage of GGBS and also with the increase in the amount of the sodium silicate solution in which the concentration of sodium hydroxide in the aqueous solution is fixed at a constant value of 10M.
