Title:

Geopolymer Cement

Value Proposition:

An improved process for the production of geopolymeric material from fly ash.

Summary Application:

Geopolymer cement can be used as binder, main ingredient in precast concrete block, fire resistance and insualation panel.

Advantages:
  • 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
