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 µ M, 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.
4. Packing
In jumbo bags of 900kg/bag or 20KG/BAG, 300KG/BAG.
5. Delivery Time
Within 10 days after confirming the order.
