Best Quality Silica Fume with Factory Price

Brief introduction: 

Microsilica fume (scientific name "silica fume, " Microsilica or Silica Fume), in the smelting of ferrosilicon and industrial silicon, silicon through the flue gas emitted by steam oxidation, the specially designed filter collected the amorphous powder like silica (SiO 2). Micro-silica fume average 0.1-0.15 μ m in diameter, the size of several cement average 1.0%. Surface area for the 15-27 m 2 / g, with strong surface activity. 

Application in concrete: 
Silica fume is widely used in concrete field especially high: Performance project, such as bridge, airport, hydropower station. Seawall, railway projects. The main functions as follow: 

(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, anti-corrosion against chloridion, refractorily and anti-freezing of concrete

(3)Enhance constructability
Improve Shotcrete, Increase Early Strength, control Temperature 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 advanced Technology, densities can be increased from 100kg/m To 700 kg/m, and is still able to be dispersed back to its natural state.
