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.*5~0.*0 µ
M, specific surface area is ****0~****0 m2/kg, and it has extremely
strong surface active.
2. Main function
Very low permeability to chloride and water intrusion.
Extremely high electrical resistivity (*0 to **0 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.
