Overview
Portland cement clinker is the backbone of cement production. We supply grinding plants and cement producers with clinker of consistent chemistry and reactivity, sourced from modern dry-process kilns.
Shipments are arranged on geared bulk carriers with pre-loading sampling and independent analysis, giving your production team predictable performance cargo after cargo.
Available grades
- Ordinary Portland ClinkerFor CEM I / ASTM Type I cement production.
- Sulfate-Resisting ClinkerLow C₃A (≤ 3.5 %) for SR and Type V cements.
- Low-Alkali ClinkerReduced Na₂O-eq for alkali-silica-sensitive applications.
