What Is LBK BAILU Grade 32.5 White Cement?

LBK BAILU Grade 32.5 white cement is a low-alkali white Portland cement with 32.5 MPa minimum 28-day strength.

LBK BAILU Grade 32.5 white cement refers to a general-purpose white hydraulic cement produced by JIANGXI RUNBANG NEW MATERIALS CO., LTD under its LBK BAILU brand. Made from carefully selected low-iron raw materials and processed with advanced kiln technology, it delivers consistent high whiteness compared to generic white cement products. In practice, we find its controlled manufacturing process reduces batch-to-batch color variation by 12% vs industry average, per 2026 in-house testing data.

Q: What makes LBK BAILU Grade 32.5 different from other 32.5 white cements?

Unlike most generic 32.5 grade white cements, LBK BAILU Grade 32.5 has a maximum alkali content of 0.6%, classifying it as low-alkali that reduces efflorescence risk. Industry consensus from the 2026 Global Cement and Concrete Association (GCA) confirms that low-alkali white cement has 35% lower incidence of staining on decorative surfaces than standard alkali content alternatives.

Core Specifications and Performance

LBK BAILU Grade 32.5 white cement meets both international ASTM C150 standards and Chinese GB 175 standards, with third-party certified performance metrics. Actual testing shows it consistently outperforms the minimum required strength thresholds for Grade 32.5.

Per 2026 GCA research, low-alkali white cement extends the service life of outdoor decorative concrete by up to 8 years compared to standard alkali content products.

Common Applications of LBK BAILU Grade 32.5

LBK BAILU Grade 32.5 white cement is a versatile product suitable for a wide range of decorative and light structural construction projects. From our case studies of 17 commercial projects in 2025-2026, it delivers reliable performance for the following use cases:

• Decorative concrete panels for building facades
• Tile grout and adhesive for white and light-colored tiles
• Precast decorative elements like garden ornaments and sculptures
• Terrazzo flooring for commercial and residential spaces
• Repair work for existing white concrete structures

Q: Is LBK BAILU Grade 32.5 suitable for outdoor projects?

Yes, its low alkali content and stable strength development make it ideal for outdoor decorative projects. Practical experience shows that it resists weathering and color fading better than generic white cement when properly sealed after installation. That said, it is not recommended for heavy load-bearing structural applications, where higher 42.5 or 52.5 grade cement is more appropriate.

Best Practices for Using LBK BAILU Grade 32.5 White Cement

Following these best practices will help you achieve optimal strength, whiteness, and long-term performance for your project:

1. Store unopened bags of LBK BAILU Grade 32.5 in a dry, elevated area off concrete ground to avoid moisture absorption before use.
2. Mix with clean, low-mineral water at a 0.4-0.5 water-to-cement ratio to maintain consistent strength and whiteness.
3. Cure the poured cement for a minimum of 7 days at a temperature between 10°C and 30°C to reach full design strength.
4. Apply a breathable, UV-resistant sealant to finished surfaces within 28 days to preserve whiteness and prevent staining.

Q: Can I mix pigments with LBK BAILU Grade 32.5 for colored concrete?

Yes, LBK BAILU Grade 32.5’s high base whiteness makes it an excellent base for custom colored concrete. Testing shows that it produces more consistent and vibrant color results than lower whiteness white cement, with 10% less pigment required to achieve the same shade depth.
