China sanyuan microsilica /silica fume supplier

详情

  Microsilica is a mineral composed of ultrafine,amorphous glass sphere of Silicon Dioxide(SiO2),which is a byproduct of producing Silicon metal or Ferrosilicon alloys. The individal particles are extremely small, approximately 1/**0th the size of an average cement grain.
  Microsilicon , is a very fine pozzolanic material. Our product comprises microscopic particle collected by filters downstream from the smelting process in silicon or ferrosilicon alloys. Adding it to concrete and other materials ,increase their density and wear resistance,which extends the life of structures.
