Brief introduction:
Microsilica fume (scientific name "silica fume," Microsilica or Silica Fume), in the smelting of ferrosilicon and industrial silicon, silicon through the flue gas emitted by steam oxidation, the specially designed filter collected the amorphous powder like silica (SiO 2). Micro-silica fume average 0.1-0.15 μ m in diameter, the size of several cement average 1.0%. Surface area for the 15-27 m 2 / g, with strong surface activity. Features Characteristics
1).Appearance is as grey&white off.
2).High electrical resistivity
3).Low Permeability
4).Superior resistance to chemical attack from chlorides,acids and sulfates
5).Low chloride ion diffusion
6).High reactive Pozzolan
7).High temperature strength
8).Improved stability ingeothermal environment
