The production of cement has affected the environment. The production of one ton of cement releases same amount of CO2 to the environment. So, there is a need to look for some other materials such as Fly ash, GGBS which can replace OPC as a binding material. To achieve this geopolymer concrete is used, with fly ash, GGBS, and Lime powder replacing cement. The principal elements of fly ash are silica and alumina, which react with an alkaline activator solution to form a gel that binds the particles in Geopolymer concrete. The alkaline activator solution is made up of Na2SiO3 and NaOH. Some additives such as GGBS, OPC and Lime powder were added which helped the concrete to cure in ambient curing condition. Different mixes were prepared by adding GGBS, OPC and lime powder in 10%, 20% and 30% of binding material and casted. Mixtures were designed for AAS/Binder content ratio as 0.35 and 0.4. AAS content was prepared with NaOH concentration as 14M and 8M and Na2SiO3/NaOH ratio as 1.5.
