Geopolymer concrete prepared from class F fly ash and mixed alkali activator of sodium hydroxide and sodium silicate solution were investigated. Sand and M-Sand were used as Fine aggregates. The aim of this project is to study the behaviour of stress and strain characteristic of geopolymer concrete by using ambient and heat curing. Also the suitability of using an existing constitutive model originally proposed by Popovics for ordinary Portland cement concrete was studied. It was found that the equation of Popovics can be used for geopolymer concrete with minor modification to the curve fitting factor.
