Silica fume
1.Instruction
Silica fume 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.
2.Main Properties
- Very low permeability to chloride and water intrusion.
- Extremely high electrical resistivity.
- Increased abrasion resistance on floors,highways,marin structures.
- Superior resistance to chemical attack from chlorides,acids,sulfates.
3.Specification
Grey Densified and undensified Micro Silica fume
