Portland Cement Type II Supplier & Exporter — Moderate Sulfate Resistant
Type II ISIRI 389 · C₃A 6.4%
Moderate sulfate-resistant Portland Type II cement conforming to ISIRI 389, with tricalcium aluminate held to 6.4% against an 8% ceiling. Reaching 450 kg/cm² at 28 days with a lower heat of hydration than Type I — the right choice for foundations in sulfate-bearing ground, drainage structures and mass concrete pours.

Bespoke Supply
Need high sulfate resistance instead?
Type V high sulfate-resistant cement, with C₃A held below 5%, is available for severe sulfate exposure. Send us your exposure class and target standard and we will confirm availability and lead time.
Applications
Type II exists for one reason — concrete that has to survive sulfate attack or shed its own hydration heat.
Sulfate-Bearing Ground
Foundations and buried structures in aggressive soil.
Drainage & Sewerage
Culverts, manholes and wastewater structures.
Mass Concrete Pours
Raft foundations and dam sections needing lower heat.
Marine & Coastal Works
Structures exposed to sulfate-rich groundwater.
Precast Pipes & Segments
Buried precast products with long service life.
Bridge Substructures
Piers, abutments and pile caps.
Retaining Walls
Earth-retaining structures in contact with soil.
Industrial Flooring
Slabs exposed to chemically aggressive environments.
Water Retaining Structures
Reservoirs and treatment plant tankage.
Packaging, Logistics & Trading Terms
How we bag, certify and ship Type II cement. Terms can be adapted by agreement — tell us what your operation needs.
- Minimum Order Quantity
- 1 × 20 ft container (approx. 25 MT) bagged. 500 MT minimum for bulk vessel. Trial quantities available for qualification.
- Packaging
- Bulk, 1.5 MT jumbo bags, or 30 × 50 kg PP/paper bags loaded inside a jumbo bag for faster loading and discharge. Bulk vessel loading for tonnages above 25,000 MT.
- Incoterms & Loading Ports
- EXW, FOB, CFR and CIF (Incoterms® 2020). Standard loading at Bandar Abbas and Bandar Imam Khomeini; other ports by arrangement.
- Quality Certification
- Batch-specific mill certificate with every shipment covering the full chemical analysis and physical tests. SGS / Bureau Veritas inspection at buyer’s cost.
- Lead Time
- 7–14 days for standard grades after order confirmation; 15–25 days for custom-milled or specially packed material.
- Storage & Handling
- Store in a dry, covered warehouse, bags off the ground and away from walls. Cement absorbs atmospheric moisture, which causes lump formation and progressive strength loss. Use within 3 months of production for full rated strength; shelf life is nominally 6 months in sealed bags under dry storage.
Certificate of Analysis
A batch-specific CoA is issued with every shipment. Third-party inspection by SGS, Bureau Veritas or an inspector of your choice can be arranged at the buyer’s cost.
