1. Instruction

micro silica fume , 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.  Micro 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. Micro silica fume 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, micro silica fume meets the requirements of ASTM C-1240. Micro silica fume 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.

3.JH97

micro silica fume  JH97 is a dry powder.

Micro silica fume JH97 is a pozzolanic materials that consisits primarily of fine silicon dioxide particles in a non-crystalline form.

Micro silica fume JH97 meets the requirements of ASTM C-1240 and contains a minimum of 97% silicon dioxide(SiO2).

Micro silica fume JH97:we have three factories in Shanxi,Yunnan and Qinghai Province,China.Stable quality and reasonable price.
