Microsilica/ Silica Fume Sio2 85% For Cement Application: Construction

We are a unique name in the industry as a leading Exporter, Manufacturer & Supplier of Microsilica/ Silica Fume SiO2 85% for Cement in Beijing, Beijing, China. Micro silica, also called silica fume or micro silica, is a byproduct of production 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, silica fume consists primarily of amorphous(non-crystalline) silicon dioxide(SiO2),its average granule diameter is 0.15~0.20um,specific surface area is 15000~20000m2/kg,and it has extremely strong surface active.

Application area of silica fume
The early strength of concrete or special cement compound to meet the oil Well,marine oil drilling platform,harbor terminals,railway bridges highways,airport runways,tunnels and urban high-rise building projects.
