The production of Ordinary Portland Cement causes atmospheric pollution due to the emission of CO2. An alternative material is tried to replace OPC in the concrete. Low calcium Fly ash, a by-product from the coal industry, which is widely available in the world contains silicate and alumina. Fly ash with alkaline solution produces alumina silicate gel that binds the aggregate to produce a good concrete called Geopolymer concrete. The compressive strength increases with the increase of fly ash fineness and thus the reduction in porosity can be obtained. The nominal mix required for M 20 grade is tried in this study. The Geopolymer concrete cubes of size 100×100×100 mm were casted and tested. The long term compressive strength of Geopolymer concrete was obtained. The Geopolymer concrete exhibits higher compressive strength with respect to age.
