Description
Introduction to Soufian Type 2 Cement
Suitable for semi-humid areas and sulfate-containing soils
Portland Type 2 Cement is a cement with moderate resistance to sulfate attack and lower heat of hydration compared to Type 1 cement. It is designed for construction projects in semi-humid regions, soils containing sulfate ions, or mass concrete applications. The cement complies with ISIRI 389 and EN 197-1 standards.
General Features of Soufian Type 2 Cement
- Moderate sulfate resistance (suitable for foundations in sulfate-rich soils)
- Lower heat generation during initial setting (ideal for mass concrete)
- Acceptable long-term compressive strength
- Longer initial setting time than Type 1, allowing extended transportation of concrete
