In recent years the use of concrete has increased day by day due to various advantages such as good strength, long life, low maintenance etc. Due to increase in uses the environment of earth is affected. The main effect of increase is temperature that melts the glaciers and increases the water level. One of the efforts to produce more environmentally friendly concrete is to reduce the use of ordinary Portland cement (O.P.C) by replacing the cement in concrete with geo-polymers. In geo-polymer concrete cement is replaced by fly ash and alkaline solutions such as sodium hydroxide (Na OH) and sodium silicate (Na2O, SiO2) to make the binder necessary to manufacture the concrete. One tone of fly ash can be utilized for manufacturing about 2.5 cubic meter of high quality Geo-polymer concrete. Test experiments proved as fly ash based Geo-polymer concrete has excellent compressive strength and flexural strength. Trial mixes were done and noted the properties of Geopolymer concrete in hardened state such as compressive strength and flexural strength. The result is show that the geopolymer concrete is again high compressive and flexural strength as comparing with the ordinary Portland cement concrete. When concrete cubes of M15, M20 and M25 was compared to geopolymer concrete cubes of 12M, 14M and 16M it was seen that the compressive strength of geopolymer concrete is increasing by 34.43,10.24 and 10.12 percentage in 28 days.
