Abstract:
Many engineers and owners, facing rising maintenance costs, recognize the significant incentive to protect existing structures from future corrosion damage by considering the use of corrosion mitigation systems. Active corrosion mitigation systems (defined here as systems that supply a protective current to the reinforcing steel) generally fall into three performance categories: corrosion prevention, corrosion control, and cathodic protection. These systems are similar in that they all provide a protective current to the reinforcing steel to mitigate corrosion activity. This article describes the differences in these systems in terms of the intended application and the intensity of the protective current required to achieve the mitigation objective.
