Geopolymer concrete is a novel material trying to be implemented in the construction field. Efforts being made by the researchers to unfurl the advantages and application of Geopolymer concrete in engineering fields. Geopolymer concrete does not require cement in making and utilizes industrial waste products. Hence replacing the OPC concrete by GPC, we not only reduce the pollution caused by manufacturing cement, but also use calcium, silica and alumina rich industrial waste. It is important to study the performance of GPC subjected to elevated temperature before considering it for structures like industrial buildings, complexes which are vulnerable to fire accidents. Present study investigates the properties like compressive strength, weight loss/gain, and Thermal energy absorption for GPC subjected to elevated temperature from 100 0 C, 200 0 C, 400 0 C, 600 0 C and 800 0 C for exposure time of 1hour and 2hours. We compare these properties of GPCs, one made using Flyash and GGBS as binders named FGGPC and the other using Flyash and Alccofine 1203 named FAGPC. From the results we found that strength of GPC increases with the rise in temperature up to 200 0 C and then rapidly decreases with further rise in temperature. Use of FAGPC is advantageous than using FGGPC on field vulnerable to fire.
