Yancheng Yuanlai Commerce & Trade Co., Ltd. Achieves Full Qualification in Product Quality Inspection, Advancing High-Performance Building Materials Innovation

March 4, 2026 – Yancheng Yuanlai Commerce & Trade Co., Ltd. announced today that all three of its core products have passed the national quality inspection with flying colors, as verified by the XX Building Materials Quality Inspection Center. The inspection results, documented in Report No. CQ-20260304-001, confirm that the Masonry 32.5 Cement, Composite 42.5 Cement, and Mineral Powder-Fly Ash Composite Ultrafine Powder fully comply with national standards, marking a significant milestone in the company’s commitment to quality and technological advancement.

The comprehensive inspection covered all key performance indicators for each product, including fineness, setting time, compressive strength, flexural strength, and chemical composition. For the Masonry 32.5 Cement, the 28-day compressive strength reached 38.6 MPa, exceeding the national standard of 32.5 MPa, while its initial setting time of 185 minutes and final setting time of 4.5 hours ensured excellent workability for residential construction scenarios. The Composite 42.5 Cement, designed for high-demand projects such as precast floor slabs and high-rise building foundations, achieved a 28-day compressive strength of 48.9 MPa, far surpassing the required 42.5 MPa, and demonstrated superior frost resistance and impermeability.

Notably, the company’s Mineral Powder-Fly Ash Composite Ultrafine Powder stood out with a specific surface area of 520 m²/kg, well above the standard requirement of 450 m²/kg. This product, a key component in high-performance concrete, has shown remarkable effectiveness in improving concrete fluidity, reducing shrinkage cracks, and enhancing durability. Test results indicate that when mixed with concrete, it can increase the 28-day compressive strength by 12.3% and reduce thermal conductivity by 8.7% in cement-based insulation materials, making it an ideal choice for marine engineering, high-speed rail projects, and green building initiatives.

“The full qualification of our products is a testament to our strict quality control system and continuous technological innovation,” said a spokesperson for Yancheng Yuanlai Commerce & Trade Co., Ltd. “We adhere to advanced production processes, including the ‘roller press + ball mill’ combined grinding system for cement and the ‘vertical mill + classifier’ ultra-fine grinding process for composite ultrafine powder, ensuring consistent product quality and performance.”

With the support of national policies promoting the high-value utilization of industrial solid wastes, Yancheng Yuanlai Commerce & Trade Co., Ltd. is poised to expand the application of its composite ultrafine powder in ultra-high performance concrete (UHPC) and precast concrete products. This achievement not only strengthens the company’s market competitiveness but also contributes to the sustainable development of the building materials industry, driving the transition toward green and low-carbon construction.
