Key Parameters: SiO₂ ≥85%, fully compliant with GB/T 27690-2023, ASTM C1240 and EN 13263 international standards; ultra-low moisture content, low loss on ignition, controlled 45μm sieve residue, specific surface area up to 25610 m²/kg, 7-day activity index reaching 118%.
Core Advantages: High purity, high pozzolanic activity, excellent fluidity and low water demand ratio. It effectively improves concrete compactness, structural strength, impermeability and corrosion resistance. With cost-effective performance, it is widely used for general high-strength concrete, conventional precast components, municipal and water conservancy infrastructure projects.
Key Parameters: SiO₂ ≥90%, higher purity, finer particle size, stronger activity and extremely low impurities. Radioactivity indexes are far below national limits, with outstanding alkali-aggregate reaction inhibition and superior chloride penetration resistance.
Core Advantages: Ultra-high purity, superfine fineness, strong reinforcing effect and excellent long-term durability. Ideal for ultra-high strength concrete, marine engineering, port terminals, high-end pipe piles, special precast elements and high-corrosion projects in the Middle East, fully meeting strict international high-standard engineering requirements.
Key Parameters: Standard S95 grade ground granulated blast furnace slag powder with high activity index, stable performance, uniform fineness and excellent hydration properties.
Core Advantages: Partial cement replacement to reduce project cost; optimizes concrete workability, lowers hydration heat, and enhances late-age strength and durability. Widely applied in pipe piles, precast components, commercial concrete and large-scale infrastructure. Combined with our D85/D90 microsilica, it achieves dual upgrading of concrete strength and durability, and has long been designated as supporting material for Qinglong Pipe Industry and Jianhua Pipe Pile.
