1. High Silicon dioxide content
      Generally the content is around 94%, also can reach 99%
2. The particle is superfine
      Average particle diameter is about 0.1μm, Only 1% of the cement particles
3. Large specific surface area
      More than 18000m2/kg and with strong surface activity
4. Great fluidity
5. Manufacturer direct and stable quality
      Now we have built 8 production bases with professional laboratory and experienced engineers.
      The annual output of the silica fume amounts to 40000 tons.
      Also we have strict quality control system to make sure the product quality, packing and transportation etc
