Abstract: Ordinary Portland cement (opc) which will be used in the Concrete releases a high amount of the carbon dioxide (CO2) in the atmosphere during manufacturing process. This leads to increase of level of greenhouse gases and hence contributes in global warming. Material like Geopolymer concrete is best alternate solution for this problem. In Geopolymer solid results from various enterprises, for example, ground granulated blast furnace slag (GGBS), Fly Ash and Rice Husk Ash are utilized as source material, basic activator arrangement blend of NaOH and Na2SiO3 is utilized to activate these source materials as to shape geopolymer mortar and furthermore some super plasticizers are utilized which acts as a binding material for coarse and fine aggregate to hold them together in the lattice. Geopolymer concrete (GPC) can be utilized rather than ordinary Portland concrete. In this work the impact of grouping of NaOH arrangement on mechanical properties of GPC is broke down by fluctuating the molarity of NaOH by ground granulated impact heater slag based geopolymer concrete. The molarity of NaOH can changed from 6M to 16M. Be that as it may, NaOH and Na2SiO3 gives quality by polymerization. All GPC blends were set up for various molarities and relieved under encompassing restoring conditions since GGBS significantly affect the setting time and the quality advancement of GPC when restored at surrounding temperature or in the immediate daylight. Geopolymer solid examples are tried for compressive quality at various ages and some functionality tests like L-box, V-funnel, and slump flow. It is found that GGBS based GPC has very low workability, it is highly cohesive and stiffened and it can be handled for about 10- 15 minutes only after this mix starts setting. It was seen that maximum quality is accomplished with 16M molarity arrangement. GGBS based geopolymer solid give huge quality at 10M, 12M molarity of NaOH arrangement.
