Silica fume:
Silica fume is also called microsilica, silicon ash, condensed or densified silica fume, its color is grey. This is a byproduct of producing silicon metal or ferrosilicon alloys, which is made in the furnace with quality quartz, coke and scrap iron.
Silica fume used in refractory can improve the liquidity and density, enhance the strength of high temperature and shock performance.
Silica fume high-strength concrete is easily to pour, long-term keep stability and higher strength, ect. It can improve the inner quality of the building, and widely used in the construction of bridges, water conservancy, and metro, ect. It is good modified material of concrete.
