Abstract

 Cathodic protection (CP) is being increasingly

used on reinforced concrete structures to protect
steel reinforcing bars from corrosion in aggressive
conditions. Due to the complexity of environmental
conditions, the design specifications in national and
international standards are still open to discussion to
achieve both sufficient and efficient protection for
reinforced concrete structures in engineering practices.
This paper reports an experimental research to
investigate the influence of chloride content on
concrete resistivity, rebar corrosion rate and the
performance of CP operation using different current
densities. It aims to understand the correlation
between the chloride content and concrete resistivity
together with the CP current requirement, and to
investigate the precision of the CP design criteria in
standards.
