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.
