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.
