Your Trusted Microsilica Supplier: Competitive Prices & Fast Worldwide Delivery
Micro silica is also called silica fume, is a byproduct of silicon metal and ferrosilicon production. Composed primarily of amorphous (non-crystalline) silicon dioxide (SiO₂), microsilica is incredibly fine, with an average particle size of 0.10~0.20μm (micron) and a remarkable surface area of 15000~27000 m²/kg. This unique structure is why microsilica is highly prized in construction — it has robust surface activity.
Since 2008, Tianjin Sunward has been a reliable microsilica supplier, offering premium-grade microsilica (silica fume) that complies with international standards, including ASTM C 1240, AS/NZS 3582.3:2016, EN 13263:2005, and JIS A 6207:2006. Our silica fume for sale is the ideal solution for enhancing concrete strength, durability, and workability. Order now to elevate your concrete performance with our silica fume sf90 for sale.
We ensure unmatched consistency in microsilica for concrete by setting up proprietary collection systems at major silicon metal and ferrosilicon factories. Our fully automated, closed-loop densifying and filling processes eliminate contamination, delivering pure, high-performance microsilica. With a 5000 m² warehouse near Tianjin Xingang and Shanghai Port, we guarantee fast shipments and bulk deliveries of microsilica.
Densified Microsilica
Good cost performance, commonly used in concrete applications.
SiO₂ Content: 85% - 97%
Bulk Density: 500 - 700 kg/m³
Undensified Microsilica
Good dispersion efficiency for refractory, fertilizer, etc.
SiO₂ Content: 85% - 97%
Bulk Density: 150 - 450 kg/m³
White Microsilica
White Micro Silica (ZSF) is a high-purity zirconia by-product containing 92–96% SiO₂, combining the strengths of silica and zirconia. Its high SiO₂ content, fine granularity, large surface area and good fluidity improve wear resistance, durability, and reinforcement in injection molding, cement/concrete, refractories, ceramics, and electronics.
Why the use of silica fume in Concrete Enhances Durability?
As a trusted microsilica supplier, we offer high-quality microsilica that significantly enhances the strength and durability of concrete. The use of microsilica in concrete is a proven method to boost durability, especially in demanding environments. Below are the key reasons why microsilica is essential for long-lasting concrete structures:
Improve Strength & Reduce Permeability: Microsilica is a fine, pozzolanic material that fills microscopic gaps in the concrete matrix, resulting in a denser, stronger structure. The use of microsilica in concrete significantly lowers permeability, preventing water, chlorides, and sulfates from corroding reinforcing steel.
Enhance Chemical & Abrasion Resistance: As a leading microsilica supplier, we provide high-quality microsilica that improves resistance to chemicals (acids, sulfates) and harsh weather. Microsilica is particularly effective in high-strength concrete, reducing wear and tear in heavy-traffic areas like highways and industrial floors.
Minimize Cracking & Extend Lifespan: By refining the pore structure, microsilica (silica fume) for sale helps prevent early-age cracking and shrinkage, ensuring long-term structural integrity. The use of microsilica in concrete enhances bond strength with steel reinforcement, preventing spalling and corrosion-related failures.
Sustainable & Cost-Effective Solution: The use of microsilica in concrete lowers lifecycle costs by minimizing repairs. Microsilica is an eco-friendly option, supporting sustainable construction. Contractors sourcing from a trusted microsilica supplier can optimize mix designs to maximize lifespan, reducing maintenance costs.
