Geopolymer concrete is a type of concrete that is produces by using the byproducts of different industries such as thermal power plant, silicon manufacture industries. The material used in the manufacturing process of GPC are FLY ASH, GGBS, RHA, METAKAOLIN. The purpose of shifting to a new binding material is pollution caused due to the manufacturing process of OPC. While manufacturing OPC billions of tons of carbon dioxide gas is released into atmosphere which is a major reason for climate change. A research says that 7% of total carbon dioxide produced throughout the world is only because of OPC. So there is an urgent need to shift to a new binding material which has similar properties that of OPC. This experimental research investigated the effect of silica fume on the fresh and hardened properties of geo-polymer concrete such as workability, compressive strength, split tensile strength and flexural strength. Test results shows that as the percentage of silica fume was being increased there was an increases till 12% there was increase in all three type of strength but further increment in the percentage of silica fumes leads to the reduction of strength as well as workability and makes the concrete tough to handle.
