We are the leading
Chinese Supplier and Exporter of Silica fume(Microsilica or
Silica dust), what has been exported to Saudi Arabia, Brazil,
India, Vietnam, Iran, UAE, Costa Rica, Nigeria, Georgia, and so
on. Welcome the potential silica fume dealer and dealership in
the foreign market for further cooperation.
Our silica fume
mostly comes from Yunan province, this means High Pozzolan
Activity. Standard specifications for silica fume used as
concrete admixture are ASTM C***0, EN ****3. Prior to the
mid****0s, nearly all silica fume was discharged into the
atmosphere. After environmental concerns necessitated the
collection intead of landfilling of silica fume, it became
economically viable to use silica fume in various applications,
in particular high-performance concrete. Effect of silica fume on
different properties of fresh and harden concrete
Silica fume is added
to Portland cement concrete to improve its properties, in
particular its compressive strength, bond strength, and abrasion
resistance. These improvements stem from both the mechanical
improvements resulting from addition of a very fine powder to the
cement paste mix as well as from the pozzolanic reactions between
the silica fume and free calcium hydroxide in the paste.
Addition of silica fume also reduces the permeability
of concrete to chloride ions, which protects the reinforcing
steel of concrete from corrosion, especially in chloride-rich
environments such as coastal regions and those of humid
continental roadways and runways (because of the use of deicing
salts) and saltwater bridges.
