Achieve Brilliant White & High-Strength UHPC
Premium white microsilica specifically engineered for GFRC & UHPC applications
- 92-96% SiO2 Content | 88+ Whiteness
- Enhanced Durability & Aesthetics
- Pure White Color - No Gray Staining
- Ideal for Architectural Applications
Why Choose Our White Microsilica?
Premium material designed for high-performance concrete applications
Unmatched Aesthetics
Unlike gray silica fume, our product ensures pure white color consistency. Achieve brilliant white and colored concrete without discoloration for architectural masterpieces.
Superior Performance
Extremely high silica content (96%) and fine particle size (1.2µm) significantly enhance compressive strength, flexural strength, and durability of UHPC and GFRC.
Enhanced Durability
Reduces concrete permeability and improves resistance to chlorides, sulfates, and carbonation. Extends service life of structures in harsh environments.
Zirconia-Derived Purity
Our unique zirconia production process yields exceptionally pure white microsilica with minimal impurities and consistent performance batch after batch.
Applications of Our Silica Fume
High-Strength Concrete (UHPC&GFRC)
Improves compressive strength, durability & resistance.
Refractory Materials
Thermal Resistance- Used in castables and gunning mixes to improve resistance to extreme temperatures and wear.
Oil Well Cementing
Seal Integrity- Enhances the density and durability of oil well cement, ensuring long-term well integrity.
Shotcrete & Precast Concrete
Reduces permeability and increases long-term performance.
Marine Structures
Corrosion Resistance- Protects against chloride penetration, extending the lifespan of marine and coastal structures.
Industrial Flooring
Abrasion Resistance- Ensures durability and performance in heavy-duty industrial floors and pavements.
