Geopolymer in recent years is being deemed as a promising alternative to cement concrete, which has remained as backbone of the construction industry. Despite GPC having potential capability of reducing carbon footprint, still many of its characteristics and mechanism to be investigated. The present study represents the utilization of bagasse ash in the production of geopolymer concrete. In order to reduce the ecological imbalance by the emission of CO2 from cement production an attempt has been made to investigate the feasibility of utilizing sugar cane ash as one of the candidate in polymer concrete by maintaining different molar concentration of sodium based alkali activated solutions. Geopolymer concrete has been casted and assessed for the fresh and harden properties. In the present work sugar cane bagasse ash replacement was done partially from 10% to 100% to determine workability and strength parameters. The objective of the work is to find the maximum extent of bagasse ash by reducing GGBS &amp; also to check the suitable silica content. GGBS has been used as a binder materials &amp; to reduce the limitations of GPC with respect to workability, Aura mix super plasticizer has been used. While comparing the results with regular concrete after 28days sun curing shows the positive effect with maximum 30% bagasse ash further increment results in decrease in harden properties such as ultimate compressive strength, flexural strength and split tensile strength. specimens were subjected to the elevated temperature to study the properties of geopolymer concrete such as residual strength, mass loss.
