Micro silica or Silica Fume, is amorphism dusty Silicon Dioxide. When melting the Ferrosilicon or the silicon metal, the Silicon steam is expelled from the flue and is oxidized and become Silicon Dioxide then it is collected by special equipment. The average size of Micro silica is Between 0.1-0.15um, which is smaller than 1% of cement's radius. Its B. E. T Fineness is 15-27m2/g.

Micro silica used in chinaware and fir-resistance material, can reduce water requirement greatly, can increase the intensity and density of concrete, improve products quality, prolong products lifespan, so it is optimal bonding agent.

Packing: 850kg/bag or 900kg/bag
