-High quality 
-Low price 
-ASTM C-1240 Densified and undensified Silica Fume for Concrete/Cement/Refractory     1.Instruction Silica fume is a byproduct of producing silicon metal or ferrosilicon alloys.It consists primarily of amorphous silicon dioxide (SiO2),its average granule diameter is 0.15~0.20 µm,specific surface area is 15000~20000 m2/kg.   2.Main Properties Very low permeability to chloride and water intrusion. Extremely high electrical resistivity. Increased abrasion resistance on floors,highways,marin structures. Superior resistance to chemical attack from chlorides,acids,sulfates. Packaging & Shipping Packing:  Jumbo bag (450kg/bag)  or small bag (25kg/bag)

Our Services R&D, Producing only microsilica, silica fume Company Information Our manufacture has been specialized in R&D and producing a series of microsilica (silica fume) for over 15 years. One of the most beneficial uses for silica fume is in concrete, fire-proof materials and oil-gas well grout. The annual output--50000T.
We can produce different content (85%, 90%,92%, 95% , 97% )of micro silicon powder products and export to more than 20 countries such as America, Japan, Korea, Australia, U.A.E., Germany, etc.
