Utilisation of fly ash and Ground Granulated Blast Slag as an alternative material in concrete reduces the use of OPC in concrete. Evolution of geopolymer concrete cured at ambient temperature broadens its suitability and applicability to concrete based structures. This paper presents the mix proportions and outcome of an experimental study on the density and compressive strength of geopolymer concrete. Fly ash was used as a base material which was made to react with sodium hydroxide and sodium silicate solution to act as a binder for fine and coarse aggregate. Ground Granulated Blast Slag was replaced in different proportions to fly ash to enhance various properties of concrete. The concrete was subjected to curing at ambient temperature. Based on the study carried out, replacement of GGBS in fly ash up to 50% produced better mechanical properties.
