Micro silica for Concrete/Refractory

1.Instruction

Microsilica , also called silica fume, is a byproduct of producing silicon metal or ferrosilicon alloys. Silicon metal and alloys are produced in electric furnaces. The raw materials are quartz, coal, and woodchips. The smoke that results from furnace operation is collected and sold as silica fume, rather than being land filled. Microsilica consists primarily of amorphous (non-crystalline) silicon dioxide (SiO2), its average granule diameter is 0.15~0.20 µm,specific surface area is 15000~20000 m2/kg, and it has extremely strong surface active.

2.Main function

  • Very low permeability to chloride and water intrusion.
  • Extremely high electrical resistivity (20 to 100 times greater than ordinary concrete).
  • Increased abrasion resistance on decks, floors, highways and marine structures.
  • Superior resistance to chemical attack from chlorides, acids, nitrates and sulfates.
