Pollution in cement production is a major environmental issue throughout the world. Geopolymer concrete is an alternate cement as well as environment-friendly material in construction field. It is also used as an alternative for ordinary Portland cement because of no emission of greenhouse gas CO2. The current limitation in geopolymer concrete has been applied in precast members. The geopolymer concrete is prepared by using fly ash, ground granulated blast furnace slag (GGBS) as base materials and combination of sodium hydroxide and sodium silicate as alkaline activators. The present study deals with alkaline solution ratio and compressive strength. SEM analysis shows bonding of metal with OPC and GPC, vibration frequency of metal with OPC and GPC for FT-IR spectra. The compressive strength of concrete is obtained and compared with cement concrete. Keywords: Fly ash, GGBS, geopolymer concrete, alkaline solution, cubes, cylinders
