Geopolymer Concrete - The Eco Friendly Alternate to

Geopolymer concrete (GPC) is an eco friendly product which uses industrial waste by-products such as fly ash (waste from thermal power plants) and ground granulated Blast Furnace Slag (waste from Iron production) as complete replacement for cement in concrete. As a result of this geopolymer concrete reduces CO 2 emissions by 80%.
