Product Description:

1.Microsilica 85%-98%

2.High fluidity

3.Low permeability

4.Meets the requirements of ASTM C-1240 

 

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.
