COMPARISON OF RATES OF GENERAL CORROSION AND MAXIMUM FITTING PENETRATION ON CONCRETE EMBEDDED STEEL REINFORCEMENT

Local attack of reinforcement is observed usually in chloride-contaminated concrete. when mechanical weakening of the concrete structure is affected by the bar section loss in the places where corrosion is intensified, the maximum penetration of the deepest pits happens to be a very relevant datum. In this work average corrosion values are compared with maximum pit depth values. Using natural corrosion tests and accelerated tests, it has been found that the maximum penetration of localized attack on steel embedded in concrete containing chlorides is equivalent to about four to eight times the average general penetration.
