Impressed current cathodic protection of rebar in concrete using Carbon FRP laminate

Carbon FRP can be used as anode in impressed current cathodic protection of rebar in concrete. Although, ICCP reduces mass loss in rebar due to corrosion, it reduces bond, too. Most appropriate protection current density is investigated that induces lowest mass loss with highest bond stress. ICCP was applied with different protection current densities to rebar in concrete, pre-corroded to three corrosion levels. CFRP was bonded to concrete surface using conductive adhesive. Protected specimens were exposed to corrosive environment. Effectiveness of ICCP was evaluated by half-cell potential, LPR, bond stress and mass loss. The appropriate protection current density is proposed.
