Rak White Cement, CEM I, 50kg, High Whiteness

Avoid direct contact with skin or eyes as moist cement can cause irritation. Use protective gear while handling and store it out of reach of children.

Yes, Rak White Cement is produced using eco-conscious practices. It has low alkali content and less than 2 ppm of water-soluble chromium (Cr6+), adhering to environmental safety standards.

It must be stored in a dry, sealed environment away from moisture to maintain quality. Bags should be placed on plastic-coated pallets and used within six months of packaging.

Rak White Cement is ideal for plastering, tiling, decorative concrete works, luxury home finishes, sculptures, and architectural projects requiring a pristine white finish.

The cement has a Blaine fineness of 395 ± 20 m²/kg, a setting time of 100 ± 30 minutes, compressive strength of 38 MPa at 2 days and 74 MPa at 28 days, and a brightness level of 87 ± 2%.

The cement is packaged in durable HDPE sack bags with a size of 50kg, ensuring superior protection and accurate dosage for both small and large-scale projects.

Key features include high setting strength, fast hardening, excellent bonding with masonry, low water absorption, good crack and heat resistance, and a smooth, bright finish for aesthetic appeal.

Rak (CEM 1) White Cement is a Grade 1, ASTM C-150 Type I white Portland cement, compliant with EN 197-1 standards. It offers a compressive strength of 52.5N, making it suitable for general-purpose and decorative construction applications.

While RAK White Cement's manufacturing process requires higher energy consumption compared to grey cement, it can be blended with supplementary materials like fly ash or GGBS to enhance sustainability without compromising quality.

RAK White Cement has a fineness of 4060 cm²/g according to Blaine's method, which ensures high performance in terms of strength and workability in concrete mixes.

The chemical composition includes CaO (67.5%), SiO2 (23.34%), Al2O3 (5.63%), and Fe2O3 (0.57%). The low iron content contributes to its high whiteness, which is measured at 91.2% on the Hunter scale.

RAK White Cement is formulated to achieve higher early and late-age strength compared to many other white cements. Its consistent quality and performance make it a preferred choice for both ready-mix and precast producers.

The compressive strength of RAK White Cement is impressive, achieving a minimum of 35-38 MPa at 2 days and 65-69 MPa at 28 days. This performance exceeds the requirements set by SANS 50197-1 for CEM I 52.5R cement.

RAK White Cement is ideal for a variety of applications, including architectural finishes, coloured mortars and plasters, decorative pavements, and precast concrete products. Its whiteness makes it particularly suitable for projects where visual appeal is essential.
