MARINE ENVIRONMENT CORROSION OF EPOXY-COATED REINFORCING STEEL. CORROSION OF REINFORCEMENT IN CONCRETE. PAPERS PRESENTED AT THE THIRD INTERNATIONAL SYMPOSIUM ON "CORROSION OF REINFORCEMENT IN CONCRETE CONSTRUCTION", BELFRY HOTEL, WISHAW, WARWICKSHIRE, MAY 21-24, 1990

Extensive corrosion of epoxy-coated rebar has been observed in the substructures of bridges in the marine environment of Florida. The corrosion developed in less than ten years, and affected both fabricated and straight rebar. The damage is accompanied by disbondment of the epoxy coating, corrosion of the underlying metal, formation of large pits and eventual concrete delamination. Laboratory experiments showed that corrosion is accelerated by fabrication bending, and that certain polarization conditions during service can promote disbondment and corrosion of the type observed in the field. A possible mechanism of corrosion is presented.(A) For the covering abstract of the conference see IRRD 831449.
