| Abstract | The performance of nine corrosion-inhibiting systems for reinforced concrete structures exposed to the severe Canadian climate was assessed in the field on bridge barrier walls. These systems were composed of one or more of the following components: concrete admixtures, reinforcing steel coatings, and/or concrete surface coatings/sealers. The field evaluation consisted of annual corrosion surveys of half-cell potential and corrosion rate, as well as laboratory testing on concrete cores. After ten years, the main reinforcement at a depth of 75 mm was found in relatively good condition. Special bars embedded at a depth of 13-mm showed signs of advanced corrosion for all systems. Non-destructive corrosion evaluation of 25-mm deep special bars indicated lower risks of corrosion for corrosion-inhibiting systems composed of concrete admixtures. |
