Product Details
Category: Cement, Hathi Cement
Product Description
Concrete made with Sulphate Resisting Cement is less vulnerable to sulphate attacks because its C3A is lower than 5% - thereby reducing the formation of Ettringite (expansive hydrates). Sulphate Resisting Cement is manufactured from a synthesis of different specific standard raw materials of high purity under strict supervision of an expert technical team.
ADVANTAGES
- Complete assurance against Sulphate Attack.
- Enhanced life and durability of Structure under aggressive conditions.
- Progressive high compressive strength.
- Corrosion resistance of steel by preventing sulphate and chloride attack.
IDEAL APPLICATIONS
- Ports, Harbors, Docks
- Dams exposed to saline and polluted water
- Construction activity in saline land
- Construction exposed to sea water, e.g. sea walls, break water, tetrapods
- Construction of sewage and drainage system
- Effluent treatment plants
- Chimney, cooling towers
- Chemicals industries, water storage, underground foundations, etc.
