—Geopolymer concrete is a cement less concrete gaining popularity globally towards the sustainable development .It is a type of amorphous alumino-silicate cementitious material which can be synthesized by polycondensation reaction of geopolymeric precursor and alkali polysilicates. Beside fly ash, alkaline solution is utilized to make geopolymer paste which binds the aggregates to form geopolymer concrete. Even though some studies could be seen in literature on geopolymer concrete, not much work has been reported in the area of development of mix design procedure.In addition, some of the conclusions are contradictory. In this paper an attempt is made to develop the mix design for Geopolymer concrete in medium grade and relative comparison has been made with equivalent mix proportions of grade of OPC Concrete in both heat cured and ambient cured conditions. About 7 different mixes for each grade is casted, tested and optimized .The design parameters like alkaline liquid to flyash ratio and water to Geopolymer solids ratio were proposed to develop the Geopolymer concrete of standard grade.
