85% densified micro silica to Middle East Concrete industry


 We have three factories in Shanxi, Yunnan and Qinghai Province, China. Stable quality and reasonable price.


Silica fume , also known as microsilica or silica dust, has been world widely used for many years in the area where high strength and durable concrete were required. Silica fume improves the properties of both fresh and harden concrete.


1. Reduce the permeability of concrete.


For provision of a concrete resistant to the most aggressive environment, the most important property is the permeability.

Lower the ingress of movement of water or chemicals; lower the adverse reactions such as sulfate attack, reinforcement corrosion.


The reaction between silica fume and the calcium hydroxide, released as the cement hydrates, provides a dense impermeable pore structure. Although the total porosity of the silica fume concrete is similar to the OPC concrete the average pore size is much finer, conducting to a large reduction of permeability.


2. 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, Silica fume can be used to reduce to the cement content of the mix.


In addition of the cost saving benefit, this will reduce the total heat of hydration and can improve the performances of the concrete in terms of chemical resistance.
