Zirconium silica ash is an amorphous, powdery, high-purity silica obtained through the oxidation of silica vapour discharged from the flue and collected by a specially designed dust collector during the smelting of desilicated zirconium in our company. The particle size is a few hundredths of the average particle size of cement. The specific surface area is 15 -27 m2/g, with strong surface activity.It is mainly used in cement or concrete admixture to improve the performance of cement or concrete, wear-resistant, scour-resistant, corrosion-resistant, penetration-resistant, frost-resistant, early-strength special concrete for dams, large reservoirs, hydropower, harbour wharves, railway bridges, highways, airfield runways, tunnels and ultra-high-rise buildings and other projects. At the same time, micro-silica powder can also be used in the production of refractory materials and ceramic products, to improve the strength and durability of the product; used in paints, coatings, resins, rubber and other polymer materials filler, can play a role in improving the comprehensive performance of the material.
