The process uses ambient temperature synthesis to produce geopolymer cement from two major industrial waste, fly ash and granulated blast furnace slag. The alumino-silicates present in raw material undergoes polymerization and polycondensation resulting into hard ceramic like material with good longevity. The cement exhibits properties similar to Portland cement and excellent durability. These cement are also fire resistant. Due to its fast setting behaviour, it can also be used for grouting and repairing.
