- Abstract
The repair principle IR – state of knowledge, regulatory consequences, current research While the repair principle IR (increasing resistivity) has become a standard procedure for the repair of carbonation‐induced reinforcement corrosion, its applicability to chloride‐induced reinforcement corrosion is still under discussion. In many cases, IR may display economic advantages at first glance, but its application is linked with an increased risk of failure. This contribution presents the fundamentals of the repair principle IR in case of chloride‐induced corrosion and the current state of knowledge both for uncracked and cracked concrete. Regulatory consequences that arise from the higher failure risk are being discussed. Corrosion monitoring is introduced as a possible means to monitor the performance of the repair measure. Finally, case studies illustrate both the risks of this repair principle and the benefits when applied successfully.
