The increasing emphasis on energy conservation and environmental protection has led to investigation of alternatives to customary building material. Effort are urgently underway all over the world to develop environment friendly construction materials which makes minimum utility of natural resources and helps to reduce green house gas emission Geopolymer concrete (GPC) is one of the most recently developed structural concretes, where industrial wastes like fly ash, rice husk, ground granulated blast furnace slag (GGBS) are utilized for complete replacement of ordinary Portland cement in concrete. A major contribution to structural concrete in the form of Geopolymer concrete was developed by many investigators with lesser grade of concrete. The contribution of green house gas emission due to ordinary Portland cement production worldwide is approximately 7%. For each ton of Portland cement manufactures, it is estimated that one ton of CO2 is released into the environment. In this connection, Geopolymer are showing great potential and does not need the presence of Portland cement as binder. Geopolymer concrete is prepared by using alkaline solution of suitable chemical composition. The ratio of mixture is 2.5 and the concentration of sodium hydroxide is 10M. The geo polymer concrete specimens are casted and tested for different types of strengths for 3, 7, and 28 days and cured at ambient temperature.
