1. Instruction
- Microsilica , also called silica fume or micro silica, is a byproduct ofproducing silicon metal or ferrosilicon alloys.
- Silicon metal and alloys are produced in electric furnaces. The rawmaterials are quartz, coal, and woodchips.
- The smoke that results from furnace operation is collected and sold assilica fume, rather than being land filled.
- Silica fume consists primarily of amorphous (non-crystalline) silicondioxide (SiO2), its average granule diameter is 0.15~0.20 µm,specificsurface area is 15000~20000 m2/kg, and it has extremely strongsurface active.
- Microsilica can be used in a variety of cementation products, such asconcrete, grouts, and mortars as well as elastomeric, polymer, refractory,ceramic and rubber applications.
- HS No.: 28112200 China Origin, microsilica meets the requirements ofASTM C-1240.
- Microsilica CAS#: 69012-64-2
2. Main function
- Very low permeability to chloride andwater intrusion.
- Extremely high electrical resistivity (20to 100 times greater than ordinary concrete).
- Increased abrasion resistance on decks,floors, highways and marine structures.
- Superior resistance to chemical attackfrom chlorides, acids, nitrates and sulfates.
