In particular, chloride-induced macroelement corrosion \nof the reinforcement is one of the bottlenecks in the service life time \ndesign of a majority of infrastructure buildings with a significant \nexposition to chloride. Corrosion monitoring offers a possibility to \ndetect the onset of corrosion events and start independent restoration \nactions at a point, where costs can be kept at a minimum.<br>The \npresentation focusses on the testing procedure and verification of the \nprototype, under conditions simulating real-life corrosion events. Color\n change is not observed when applying zero-load currents, but occurs \nwithin minutes after raising either the potential or current to levels \ntypical for corrosion events. The color change is persistent even after \nturning the power source off. We applied potential controlled current \nprofiles as well as voltage controlled current profiles to the device, \nalso with respect to peak current profiles to show the response of the \nsystem under realistic circumstances. Also, we investigate the influence\n of zero-load current and voltage events during the passive state of the\n reinforcement steel after passivation. Furthermore, experiments on \nreinforcement steel and reinforced concrete samples are shown as a \nproof-of-principle experiment.<\/p>","protected":false},"excerpt":{"rendered":"<p>T.
