White silica fume description

What is white silica fume?

Winitoor's white silica fume is high purity,consistent properties and lightness of colour,same standard as  Elkem microsilica grade.

With a Colour Reflection value typically more than 75%, Elkem microsilica grade white silica fume  is whiter and more consistent than many alternative grades of silica fume.

Note that Elkem microsilica grade white silica fume   is not a pigment and the colour of any concrete or mortar mixture made with Elkem Microwhite® will be a function of the general mix design.

Characteristic of white silica fume

Micro-silica fume/white silica fume is a by-product produced during the process of producing electrofused zirconium and zirconium. It is mainly used in unshaped refractory materials, construction, ceramics, pigments, and chemical industries.

It can be used for cement concrete in construction, can reduce the amount of cement in concrete, eliminate segregation of materials, increase the strength of concrete, enhance abrasion resistance and durability, and improve the corrosion resistance of steel bars; in amorphous refractory materials, Effectively reduce the amount of water added, has good thixotropy, and can play the role of low temperature bonding, is the best bond, binder, additives and performance improvement blends; for the ladle of unshaped castables, can To high temperature and molten steel insulation effect; used in high alumina brick, magnesium brick, sliding nozzle brick, kiln furnace and other high temperature equipment, refractories can improve the product quality level, as other ordinary refractory materials can not play the role.
