Pollution caused by cement production is a major environmental issue throughout world. Geopolymer concrete is an alternative material to the cement as well as environment friendly material in the construction field. The geopolymer concrete is prepared without cement by using fly ash as base material and combination of sodium hydroxide and sodium silicate as an alkaline activator is 12 mole. Thus silicate and alumina available in fly ash react with alkaline solution to produce alumina silicate gel that binds, the fine and coarse aggregates to produce a good concrete. The hot curing method, ambient and external exposure curing is proposed to adjust with the condition of cast in situ environment. The different grades of geopolymer concrete such as M 20, M 30, M 40, M 50 and M 60 developed and tested for density, workability and compressive strength to compared with cement concrete and proves GPC is an alternative eco-friendly concrete.
