White Cement

Description

1. Product Overview
White Cement is a high-purity, iron-oxide-deficient hydraulic binder engineered for superior whiteness, color consistency, and architectural finish. It is primarily used in premium construction, precast concrete, and decorative applications where aesthetic quality and structural integrity are paramount. The key value proposition lies in its ability to deliver brilliant, uniform whiteness without compromising mechanical strength, enabling architects and contractors to achieve high-end visual outcomes with standard concrete workability. Strategically, white cement is critical in global markets shifting toward value-added, low-maintenance building materials that reduce downstream finishing costs.

2. Key Specifications & Technical Characteristics

• Chemical composition: >70% CaO, <0.35% Fe₂O₃, low alkali content (Na₂O eq. <0.60%)

• Purity/grade: ASTM C150 Type I, EN 197-1 CEM I 52.5 R, or equivalent white Portland cement

• Physical characteristics:

  • Fine white powder; Hunter whiteness index ≥ 90

  • Particle size: D90 < 45 µm; Blaine fineness: 4,500–5,200 cm²/g

  • Bulk density: 1.15–1.25 g/cm³ (loose), 1.50–1.60 g/cm³ (tapped)

• Packaging options: 25 kg / 40 kg multi-ply paper bags, 1.5 MT jumbo bags, or pneumatic bulk tanker delivery

• Shelf life: 6 months in dry, covered storage (humidity < 70%)

3. Core Industrial Applications

• Primary industries: High-end construction, precast concrete manufacturing, terrazzo, tile grouts, artificial marble, and architectural façade systems.

• Operational use cases:

  • Decorative concrete panels and cladding

  • Self-leveling underlayments and white mortar

  • Colored concrete (acts as ideal base pigment carrier)

• Performance advantage: White cement reduces or eliminates need for surface painting or coating, lowering lifetime maintenance costs. Its low iron oxide content prevents yellowing under UV exposure, ensuring color stability. Compared to gray cement, it allows consistent pigment dispersion with 20–30% less pigment volume, reducing raw material cost per ton of colored mix.

4. Competitive Advantages

• Quality consistency: ISO 9001:2025 certified batch control with ±2% whiteness deviation across production runs.

• Supply reliability: Dedicated production lines with 50,000 MT monthly capacity; 99.2% on-time delivery record.

• Logistics capability: Multimodal shipping (breakbulk, containers, Ro-Ro) from 3 strategic port hubs (Asia, MENA, LATAM).

• Price competitiveness: Direct mine-to-factory integration reduces landed cost by 8–12% vs. regional competitors.

• Sustainability: Low-CO₂ clinker formula (620 kg CO₂/MT vs. industry avg. 780); available with environmental product declaration (EPD).

• Technical support: Free mix design optimization, on-site QC training, and digital certificates of analysis per lot.

5. Commercial & Supply Information

• Minimum order quantity (MOQ): BULK 20 MT (loose in tanker or big bags)

• Loading capacity: 26 MT per 20’ GP container (28 MT per 20’ open-top container for jumbo bags)
