White Silica Fume (color may vary slightly) – the Ultimate Pozzolan
White micro silica fume (powdery) is a very rare micro silicon powder. It is very strict on the raw material and production process. Its production is very small, and it can be used in superfine fillers with high whiteness requirements, such as grout, sealant, repair agent and so on.
White silica fume is the by-product of high performance decorative concrete. The color of our white silica fume may vary from pure white to slighly off white.
White Silica 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.
The temperature of the white micro silica fume is 1800 degrees, higher than the ordinary micro silica fume, so in the refractory industry, white micro silicon powder is more popular.
Improve 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. Thanks to its pozzolanic effect (reaction with Ca(OH)2 ), and therefore to the strength improvement.
At present, the domestic micro silica fume ordinary production line can hardly reach the technological conditions for the production of white microsilica. So the price of white micro silica fume is much higher than that of ordinary silica fume powder.
Due to China large source, there are many silica fume manufacturers in China, famous companies are Sichuan Langtian, Huatuo, Yuanye, Giant, Sanyuan, Winitoor, Henan Superior Abrasives, and other.
In which Henan Superior Abrasives is the very famous microsilica supplier, so our factory can meet customers’ various requirements. If you have any need, please contact us by E-mail sales@superior-abrasives.com or directly contact us on the following form, thank you.
