Microsilica for Concrete/Refractory

 

 

Product Description

 

Microsilica is a byproduct of producing silicon metal or ferrosilicon alloys.It consists primarily of amorphous silicon dioxide (SiO2),its average granule diameter is 0.15~0.20 μm,specific surface area is 15000~20000 m2/kg.Mainly used for high transparency, high resistance to tear silicone rubber, silicone grease, sealed packaging materials such as capacitors.

 

 

Main Properties

 

  • 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.
