Densified Silica fume/microsilica 94 grade for concrete
Silica fume/microsilica, also called as micro silica, silica dust, is a by-product of producing silicon metal or ferrosilicon alloys. Silica fume consists primarily of amorphous (non-crystalline) silicon dioxide (SiO2).
(1)Enhance the mechanical properties of concrete
The most important character for concrete – high strength and early strength has been used in substructures of high-performance concrete.
(2)Improve the durability of concrete
Significant improvements can be seen in the permeability resistance, abrasion resistance, chemical resistance and anti-freezing of concrete.
(3)Enhance constructability
Contractors can take advantage of the properties of silica-fume concrete to expedite projects or to achieve properties that might otherwise be impossible to achieve.
(4) Increase density, decrease freight cost
By densifying silica fume utilizing the Russil Tech Process allows the media to become more flowable and controllable .Using Elkem’s Technology, densities can be increased from 100kg/m³ to
700 kg/m³, and is still able to be dispersed back to its natural state.
