Abstract
The role of chloride is very much significant in the corrosion of reinforced concrete structures. This chloride may be contributed by the atmosphere, water used for mixing concrete and the contaminated aggregates and cement. If this chloride is removed from concrete and the chloride level is brought to less than allowable level, then the reinforced concrete structure may be saved from corrosion to a certain extent and the longevity of the structure increased. This paper explains a method of removing chloride from concrete using electrochemical technique based on the fact that on electrolyzing an electrolyte containing chloride ion, by passing a small current, chloride ion moves towards the anode. Different currents were applied and the amount of chloride removed was estimated using analytical technique
