Cement & Concrete Materials
Silica Fume
Institutional bulk sourcing profile for Silica Fume, structured around certified specifications, project tonnage and GCC delivery requirements.
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 | Undensified / densified silica fume |
| Reference Standards | ASTM C1240; EN 13263-1; project high-performance concrete specification |
| Chemical / Material Composition | SiO2 typically ≥85% by ASTM C1240; moisture, LOI and alkali limits per certificate |
| Blaine Fineness / Gradation | Ultrafine material; BET specific surface commonly about 15,000–30,000 m²/kg rather than conventional Blaine |
| Setting / Performance Parameters | Used as SCM; dosage affects rheology and early strength and must be established by approved mix design |
| Packing | 15–25 kg bags, 500–1,000 kg bulk bags, or slurry where available |
| Delivery Basis | FOB / CFR / CIF; moisture-protected packaged delivery |
Industrial & engineering applications
Application context for institutional procurement
Silica Fume is specified in institutional construction procurement where high-performance concrete for marine piles, bridge decks, towers, industrial floors and very low-permeability structural elements. 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.
