The primary advantage of geo polymeric concrete is the decrease in ecological effect in agreement with the concept of sustainable development. The present investigation thinks about the quality, and transport properties of GGBS-and fly debris based geopolymer mortars with different level of steatite powder. The main variables investigated were the hybrid binder of geopolymer mortar. In this present study fly ash and GGBS is partial replacement with different amounts of steatite powder (soap stone) 0%,10%, 20%, 30%, 40% & 50% to obtained the mechanical properties such as compressive strength and split tensile strength. For comparison, one mixture of ordinary portland cement mortar (OPC) is also studied. The alkali activators are prepared by combining NaOH and Na2SiO3 solution in the ratio of 2.5 and NaOH concentration 10M. The flyash based Geopolymer mortar specimens are heat curing (oven dry) at 70C for 48 hours and ambient curing was done in GGBS based Geopolymer mortar. Test results were obtained that, when increasing percentages of fly ash partial replaced with the steatite powder is gradually increased the strength and the proportion of steatite powder 30% are the optimum range value. © Published under licence by IOP Publishing Ltd.
