Technical & chemical specifications
Procurement specification grid
The values below are procurement reference points. The signed specification, producer certificate and approved laboratory results govern each order.
| Parameter | Specification / Commercial Basis |
|---|---|
| Type / Class | Portland Grey Clinker for cement grinding |
| Reference Standards | EN 197-1 constituent requirements / producer specification / buyer chemistry |
| Chemical / Material Composition | Typical mineral phases: C3S 45–65%, C2S 15–30%, C3A 4–12%, C4AF 6–12%; LSF/SM/AM and free lime by contract |
| Blaine Fineness / Gradation | Not applicable before grinding; clinker nodules and grindability are specified instead of Blaine |
| Setting / Performance Parameters | Not applicable to delivered clinker; cement setting performance is assessed after controlled grinding with gypsum/additions |

| Delivery Basis | FOB / CFR / CIF bulk shipment with loading rate and laycan agreed |
Industrial & engineering applications
Application context for institutional procurement
Grey Clinker is specified in institutional construction procurement where cement grinding plants producing OPC, blended cement and project-specific binder systems for regional construction markets. For GCC projects, technical evaluation should begin with the exact product type, governing ASTM or EN standard, chemistry or material composition, fineness or grading, performance criteria, packing mode and delivery basis. Cementitious materials used in marine structures, high-rise foundations, mass concrete and precast production may be subject to sulfate exposure, heat-of-hydration, permeability, strength-development or durability requirements that must be stated before quotation. AL BASAM coordinates bulk sourcing against the buyer’s approved specification, total metric tonnage, destination terminal or project site, shipment window and preferred Incoterm. The transaction file can be aligned with independent laboratory testing, factory certificates, safety data and origin/shipping documents as applicable to the product and jurisdiction. Final acceptance remains governed by the signed contract, producer certificate and project-approved test results. This requirement-led format helps procurement officers compare technically compliant offers instead of comparing price alone.
Quality compliance & documentation
Institutional transaction document package
The contracted document set is confirmed in the offer and may include the following, subject to product, origin, destination and buyer requirements:
- Independent third-party laboratory or inspection report from SGS, Bureau Veritas, Intertek, or another agreed inspector where contracted.
- Producer, quarry or factory test certificate identifying the supplied lot / batch and applicable specification.
- Factory Production Control (FPC) evidence and Safety Data Sheet (SDS/MSDS) where applicable to the material.
- Packing list, commercial invoice and certified Bill of Lading matching the contracted shipment.
- Legalized or certified Certificate of Origin when required by the buyer, bank, customs authority or destination market.
- Customs clearance / export manifests and project-specific inspection or conformity certificates where required.
