Effect Of Impressed Current On Corrosion Of Reinforcing Bar In Reinforced Concrete
Abstract
Corrosion of steel reinforcing bar is one of the major causes of premature deterioration reducing service life of
reinforced concrete (RC) structures. This increases maintenance and repair cost of the RC structures. In RC structures,
corrosion of steel in natural condition is very slow process. Hence generally accelerated corrosion techniques are used in the
laboratory to simulate natural corrosion process. An experimental work was carried out to study effect of impressed current
on corrosion of steel reinforcing bar in concrete. In this experiment, three different voltages 4V, 6V and 10V were used and
was impressed on reinforced bar in concrete. Cylindrical specimen of 100mm diameter and 200mm height reinforced with
bar diameter 16mm and 20mm concentrically were used and studied for the effect of different voltages applied.
