| Oxide | Indicative value | Buyer relevance |
|---|---|---|
| CaO | 65.0% | Supports balanced clinker phase development for cement performance. |
| SiO2 | 21.0% | Important for calcium silicate balance and grinding output. |
| Al2O3 | 5.0% | Relevant to aluminate content and cement setting behavior. |
| Fe2O3 | 3.5% | Stable iron oxide presence for kiln and cement chemistry. |
| MgO | 1.0% | Controlled magnesium oxide level for specification review. |
| Free lime | 0.8% | Controlled free lime level; exact values confirmed per batch. |
Laboratory verification
A clinker cooler sample dated 29-01-2026 showed an apparent density of 1.385 g/L and a controlled particle size distribution. The cumulative residue increased steadily across the sieve range, supporting predictable mill processing.
