La description

Silica fume, 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.
