Corrosion is
one of the major problem in R.C.C. Construction facing the civil engineers these
days. Chloride
intrusion and the carbonation are the two extensive
deteriorating processes that cause the depassivation of steel embedded in
concrete, leading to damage to the concrete structures and the costs of repair
become substantial. In this paper an attempt has been made to study the effect
of compressive strength of the concrete on the
corrosion of three grades of
steel, viz., the plain Mild Steel bars, HYSD bars and CRS (Corrosion Resistant
Steel), in a laboratory accelerated corrosion test by classical mass loss
measurement technique which is the only method to assess the corrosion rate
quantitatively.
