Applications

White cement costs more than grey for one reason, and it is the reason you would buy it — the colour of the finished surface.

Precast Cladding Panels

Architectural facade panels where finish is the product.

Terrazzo & Polished Floors

Binder for terrazzo, marble chip and polished concrete.

Coloured Concrete

Neutral base that lets pigment read true.

Cast Stone & Reconstituted Stone

Architectural stone substitutes and ornament.

Tile Adhesive & Grout

White-body adhesives and joint grouts.

Swimming Pool Finishes

Bright pool plaster and marbelite renders.

GRC & Fibre Concrete

Glass-reinforced concrete for thin architectural sections.

Decorative Renders

Exterior render and monocouche systems.

Sculptural & Ornamental

Statuary, balustrades and architectural detailing.

Packaging, Logistics & Trading Terms

How we bag, certify and ship white cement. Terms can be adapted by agreement — tell us what your operation needs.

Minimum Order Quantity
1 × 20 ft container (approx. 25 MT) bagged. Trial quantities available for colour and strength qualification before a full order.
Packaging
50 kg PP or paper bags loaded inside a jumbo bag, or 1.5 MT jumbo bags. Clean, dedicated handling throughout — white cement picks up contamination easily.
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 quality certificate with every shipment covering loss on ignition, insoluble residue, sulfate and chloride content to EN 196-2, and compressive strength, setting time and soundness to EN 196-1 and EN 196-3.
Lead Time
7–14 days for standard grades after order confirmation; 15–25 days for custom-milled or specially packed material.
Storage & Handling
Store dry and covered, bags off the ground, strictly segregated from grey cement and any source of iron staining. Contamination that would be invisible in grey cement will show in a white finish.

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.

Ready to quote

Send us your grade, tonnage, destination port and packaging and we will return a firm FOB/CFR/CIF price with lead time.

White Portland Cement — Frequently Asked Questions

What makes white cement white?
The absence of iron and manganese. Grey Portland cement takes its colour from the C₄AF phase, which is iron-bearing. White cement is made from raw materials selected for very low iron and manganese content and burned with a clean fuel, then ground in mills lined to prevent iron pickup. Everything else about it behaves like ordinary Portland cement.
What does CEM I 42.5 N mean?
It is the EN 197-1 designation. CEM I means pure Portland cement with no more than 5% minor additional constituents. 42.5 is the 28-day compressive strength class in MPa, with a 62.5 MPa upper bound. N means normal early strength, as opposed to R for rapid — so 2-day strength must be at least 10.0 MPa.
Can I mix white cement with grey?
Technically yes, but you lose the point of buying it. Even a small proportion of grey cement will visibly dull the finish, and the result is very hard to match batch to batch. If you are using white cement, keep the silos, mixers, tools and aggregate stockpiles segregated from grey work.
Does the aggregate matter?
Enormously. White cement only accounts for the paste; the aggregate is most of the visible surface once the concrete is ground or exposed. Pair it with white or light-coloured aggregate — white limestone, marble chip, silica sand — or the finish will read as the aggregate colour, not the cement colour.
Why is chloride content limited to 0.10%?
Chloride promotes corrosion of embedded steel reinforcement. EN 197-1 caps it at 0.10% for CEM I, and it matters particularly in thin architectural sections where cover to the reinforcement is minimal and any rust staining would be immediately visible on the face.
How should white cement be stored?
Dry and covered, off the ground, and strictly segregated from grey cement and from any source of iron staining including rusty steel, tools and skips. Use within 3 months of production for full rated strength.
