Instruction
*Microsilica , also called silica fume or micro silica, 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.
*Silica fume consists primarily of amorphous (non-crystalline) silicon dioxide (SiO2), its average granule diameter is 0.15~0.20 µm,specific surface area is 15000~20000 m2/kg, and it has extremely strong surface active.
*Microsilica can be used in a variety of cementation products, such as concrete, grouts, and mortars as well as elastomeric, polymer, refractory, ceramic and rubber applications.
*HS No.: 28112200 China Origin, microsilica meets the requirements of ASTM C-1240.
*Microsilica CAS #: 69012-64-2
Main function
*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.
