SRC - Sulfate-resistant cement
HIGH-PERFORMANCE PROTECTION FOR SULFATE-RICH ENVIRONMENTS
Shield, our Sulfate-Resisting Portland Cement (SRC), is a specialized cement engineered to protect concrete structures exposed to high sulfate concentrations in soil, groundwater, or marine environments. With a fully integrated production process from quarry to finished cement, we maintain complete oversight of every stage to ensure reliable performance and lasting durability.
Shield is used in structural and high-end infrastructure projects, including foundations, piles, underground structures, mass concrete, precast elements, sewage treatment plants, and blinding/PCC applications where durability and resistance to chemical attack are essential. Applications include structural concrete exposed to sulfate-rich soils or groundwater, blinding/Plain Cement Concrete (PCC), sewage treatment and industrial structures, mass concrete and large foundations, piles, precast concrete, and underground works.
Features and benefits
- Excellent durability: High resistance to sulfate attack due to low C₃A content, minimizing internal expansion and deterioration.
- High early and final strength: Strength class 42.5 R supports rapid and reliable construction.
- Cost efficiency: Slump retention at lower admixture dosage and high early strength reduce material and labor costs.
- Consistent quality: Controlled production ensures reproducible results across projects.
- Certified performance: Conforms to BS EN 197-1:2011 (CEM I SR) and ASTM C150-2016 (Type V), meeting international quality standards.
