The corrosion of steel in concrete structures such as bridges, roads, buildings, dams, etc. is a world wide phenomena that leads to structural weakness and degradation.

3. CORROSION
For steel reinforcement to corrode, the passive oxide layer on the steel must fail.
If the concrete cover that protects the reinforcing steel is damaged and the bond
between the concrete and steel reinforcing bar is ineffective, the steel’ s passive
layer will break down and active corrosion of the steel will occur.

Concrete is more widely used than
any other manmade material and has
been a construction staple for
centuries.

Chloride-induced corrosion is the
single largest problem for aging
concrete highway bridges,
particularly in marine environments
or areas where road salts are used.
