Abstract: Geopolymer Concrete(GPC), an ecofriendly material is being used as an alternative to Ordinary Portland Cement Concrete in many areas. Research in the area of Geopolymer is acquiring strength and results predict that Geopolymer possess better engineering properties than the ordinary cement concrete under conventional conditions. Many literatures are available in the vicinity of Geopolymer concrete whereas only a few threw lime light on the residual strength of GPC after being exposed to raised temperatures. In this study, Flyash based Geopolymer Concrete were casted for different molarities and cured in two regimes separately under ambient and heat condition. These specimens were then exposed to elevated temperature of 800OC for 1 hour and their mechanical properties such as compressive strength and split tensile strength were analyzed. The tests were carried out under normal and rapid cooling conditions. The workability of the concrete were also determined using the compaction factor test. Results predict that Geopolymer Concrete possesses better residual strength at 13M and workability was found to decrease with increase in molarity of the NaOH solution.
Keywords: Elevated Temperature, Flyash based Geopolymer, Heat Curing and Ambient Curing.
