We supply Micro Silica (also known as silica fume) products to the following industries :-
White Microsilica ( Silica Fume ) – the Ultimate Pozzolan
White Microsilica fume (powdery) is a very rare micro silicon powder. It 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, repair agent and so on.
White Microsilica ( 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 microsilica fume is 1800 degrees, higher than the ordinary microsilica 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.
