In Twenty First century infrastructure development concrete has come out as the dominant construction material due to its longevity and strength. The main component used in the concrete preparation is ordinary Portland cement whose production release large amount of carbon dioxide into atmosphere that causes greenhouse effects. Various surveys suggest industries around the globe contribute about 6%of carbon dioxide that is releasing into the atmosphere. In spite of this major environmental concern, we cannot reduce the use of ordinary Portland cement for making concrete. In this study concrete is prepared by using geopolymer technology i.e. by mixing fly ash, ground granulated blast furnace slag, sodium silicates, sodium hydroxide are mixed. Specimen curing is done at regular intervals of 3 days, 7days, and 28days. Compressive, split and flexural strength obtained after 3 days, 7 days and 28 days. Acid, Sulphate test and permeability test done for 14 and 28 days of curing the specimen. More strength occurred at mix 5 of fly ash 30% and GGBS 70%. Keywords: fly ash, GGBS, compression strength, split tensile, acid attack, flexural strength.
