The objective of this research work was to produce a carbon dioxide emission free cementitious material. The geopolymer concrete is such a vital and promising one. In this present study the cement is replaced by GGBS(Ground Granulated Blast Furnace Slag) and Fly Ash .The Alkaline liquids used in this study for the polymerization process are the solutions of sodium hydroxide (NaOH) and sodium silicate (Na2SiO3). A 10 Molarity solution was taken to prepare the mix. The cube compressive strength was calculated for 10 M solution for different mix Id i.e. G10F90, G20F80, G30F70, and G40F60 (Where F and G are, respectively, Fly Ash and GGBS and the numerical value indicates the percentage of replacement of cement by fly ash and GGBS). The cube specimens are taken of size 150 mm x 150 mm x 150 mm. Ambient curing of concrete at a temperature of 35-400c was adopted. In total 6 cubes and 3 beams were cast for different mix Id and the cube and beam specimens are tested for their compressive strength at age of 7 days, 14 day and 28 days respectively. The result shows that geopolymer concrete gains strength with increase in the GGBS content without water curing at ambient temperature. Also the strength of Geopolymer concrete was increased with increase in period of curing.
