White Microsilica is also called as White Silica Fume, white micro silica or white zirconia silica fume, produced from desilication in zircon sand melting, is widely used in monolithic refractories, Castable materials by adding silica powder can change the structure of monolithic refractories, improve its rheological property, enhance intensity, and increase its service life.

White Silica Fume is an untral fine white silica powder, it's also an undensified silica fume. White silica fume used in concrete, mainly improves the properties of both fresh and hardened concrete. it is added to portland cement concrete to improve compression strength, abrasion resistance, bond strength and durability. it also reduces chloride ion permeability and bleeding.

Dosage: replace 5% – 10% of your portland cement




White Silica Fume is very strict on the raw material and production process and it can be used in superfine fillers with high whiteness requirements, such as grout, sealant, and repair agent so on.

White Microsilica Fume) improves the properties of both fresh and hardened concrete. The most important property is the permeability, Lower the ingress of movement of water or chemicals; lower the adverse reactions such as sulfate attack, the reaction between silica fume and the calcium hydroxide, released as the cement hydrates, provides a dense impermeable pore structure.

White Micro Silica Fume's temperature is 1800 degrees, higher than the ordinary microsilica fume, so in the refractory industry, white micro silica powder is more popular.

White Zirconia Silica Fume Improves the mechanical performances of concrete. The Silica fume reacts with the cement paste to form additional strong Calcium Silicate Hydrate (CSH) providing higher strength. Silica fume reduces bleeding and enhances the cement paste bond to the aggregates.

White Zirconium Silica Fume has the following features: High reactivity, Low content of alkali oxides, Small average particle size, Low PH value., etc.
