Cathodic Protection Developments for Prestressed Concrete Components

M. Funahashi / J. Wagner / W. T. Young

This is the final report in a study that evaluated the feasibility of using cathodic protection of prestressed concrete bridge members. The interim report (FHWA-RD-92-056), published in February 1993, presented laboratory data showing that cathodic protection will generate hydrogen on high-strength steel embedded in concrete if the potential is more negative than the thermodynamic hydrogen evolution potential. The hydrogen generated will enter the steel and will cause a loss in ductility that will adversely affect the steel's performance if a notch is present. In addition, conductive paints and polymers were evaluated as anode materials.
