Siliciumdioxidasche

Microsilica (Silica fume), they used in concrete. itcan improve concrete's properties suchas compressive strength, bond strength and abrasion resistance, reduces permeability, and therefore helps in protecting reinforcing steel from coorrosion. at the same time, Microsilica can be used in the production of refractory and porcelain to raise intensity and durability, it also can be used in paint,coating,resin,rubber and other high molecular as a filler material to improve the material overrall performance
