This paper presents the results of long-term experimental tests aimed at studying the effects of cathodic prevention on the critical chloride threshold for the onset of pitting corrosion on steel bars in concrete. Cathodic prevention is applied when the structure is newand rebars are still passive being in contact with alkaline and chloride-free concrete. The results obtained showed that even very low values of current densities can increase the critical chloride threshold and, therefore, contribute to increase the service life of reinforced concrete structures in chloride-bearing environments.

Abstract
This paper presents the results of long-term experimental tests aimed at studying the effects of cathodic prevention on the critical chloride threshold for the onset of pitting corrosion on steel bars in concrete. Cathodic prevention is applied when the structure is newand rebars are still passive being in contact with alkaline and chloride-free concrete. The results obtained showed that even very low values of current densities can increase the critical chloride threshold and, therefore, contribute to increase the service life of reinforced concrete structures in chloride-bearing environments.File in questo prodotto:
