Brief Description

Description :

Inexpensive raw material. Geopolymer cement is new type of alumino-silicate binder and considered alternative to Portland cement. During synthesis, the alumino-silicates present in feedstock undergoes polymerization and polycondensation resulting into hard ceramic like material with good longevity Meet the properties of Portland pozzolana cement as mentioned in IS 1489:1991. These cements are ~10% more durable than OPC and are fire resistant upto 900°C. Uses ambient temperature synthesis and generates 70% less C02 than Portland cement.
