Product Description
Silica fume/microsilica also called as micro silica, silica dust,
which is a by-product of producing silicon metal or ferrosilicon
alloys. Silica fume consists primarily of amorphous
(non-crystalline) silicon dioxide (SiO2). The individual particles
are extremely small, approximately 1/**0th the size of an average
cement particle. Because of its fine particles, large surface area,
and the high SiO2 content, silica fume is a very reactive pozzolan
when used in concrete. The quality of silica fume is specified by
ASTM C ***0 and AASHTO M **7.
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 **0kg/m³ To **0 kg/m³ ,
and is still able to be dispersed back to its natural
state.
