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
