Microsilica (Silica fume) used in concrete and refractory.
it can be improve concrete's properties such ascompressive strength, bond strength and abrasion resistance,reduces permeability, and therefore helps in protecting reinforcingsteel from coorrosion.
at the same time, Microsilica can be used in the production ofrefractory and porcelain to raise intensity and durability,it also can be used in paint,coating,resin,rubber and other highmolecular as a filler material to improve the material overrallperformance
