With increase in industrialization the use of concrete has increased the production of cement which is not environment friendly as it has increased damages to the nature in search of limestone and energy involved. Rice Husk Ash is a waste product which is rich in silica andimproper disposal of rice hush ash (RHA) leads to air pollution and land fill problem. The Rice Husk Ash in presence of Silica – Alkali reactor acts as a binding material and can be used effectively in formation of geopolymer mortar. This study was as such carried out to investigate the properties of geopolymer concrete made with rice husk ash to check the suitability as a construction material. In order to achieve the objectives, the geopolymer mortar is being casted with mixture of Sodium Hydroxide and Sodium Silicate as silica alkali reactor with variable proportion of Alccofine i.e. 10%, 30% and 50% The compression strength was also compared with different molarity of Sodium Hydroxide i.e. at 8 Molar, 12 Molar and 16 Molar solutions. This strength was further studied by varying temperature of curing at 27⁰C and elevated temperature curing i.e. 90⁰C. The chemical composition and microstructure of sample were studied through Energy Dispersive X-ray spectroscopy test (EDX) and Scanning Electron Microscopy test (SEM).
