 Micro Silica Fume for Cement

 

 1. 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

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.
