Investigation of mechanical properties of corroded reinforcement using simulated corrosion

This paper reports the experimental results of simulated corrosion performed on reinforcement specimen to investigate the effect of corrosion on their mechanical properties, and particularly, to clarify some confusions caused by the contradictory results reported by different researchers who used the reinforcements corroded electrochemically. The removal of metal from a reinforcement surface caused by corrosion was simulated by mechanically machining the reinforcement with specified attack penetration and localization length, before it was subjected to a tension test to examine the variation of its mechanical properties. On basis of the experimental results, it has been found that the reduction of strength of corroded reinforcement was caused by the maximum penetration that was beyond the average penetration determined by weight loss, while the greater decrease of reinforcement elongation was due to the distribution of different residual sections of corroded reinforcement along its length.
