TL;DR: In this article, the authors focus on the chloride and carbonation induced corrosion of steel in concrete and present transport mechanisms and electrochemical concepts for preventative measures, condition assessment and repair techniques.

TL;DR: In this paper, the principles on which the technique is based and the various protecting effects induced by the cathodic polarization of reinforcement are illustrated; the differences between cathodic protection applied to control corrosion rate of chloride contaminated constructions and that applied to improve the corrosion resistance of the reinforcement of new structures expected to become contaminated are underlined; and the negative consequences of the method and the way to control them are shown.

TL;DR: In this article, the authors focus on the chloride and carbonation induced corrosion of steel in concrete and present transport mechanisms and electrochemical concepts for preventative measures, condition assessment and repair techniques.

TL;DR: In this article, the effects of stray current on the corrosion behavior of steel in concrete have been studied, with regards to both corrosion initiation and propagation, and it has been shown that DC current can induce corrosion initiation on the reinforcement in the anodic zone only after it has circulated for a certain time, which depends on anodic current density, the presence of chloride in the concrete and interruptions in the current.

TL;DR: In this article, the principles of cathodic protection for atmospherically exposed concrete structures, the various protecting effects induced by the cathodic polarization and tests and field experience results are discussed.
