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
Â
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.
