micro silica

Micro silica( Silica fume), they used in concrete, it can improve concrete’s properties such as compressive strength, bond strength andabrasion resistance, reduces permeability,and therefore helps in protecting reinforcing steel from corrosion. At the same time, Micro slica can still be used in the procustion of refractory and porcelain, to rais intensity and durability,it alsocan be used in paint, coating resin rubber and other high molecular as a filler material to improve the material overall performance
