This is the final report in a study that evaluated the feasibility of using cathodic protection on prestressed concrete bridge members. Four pretensioned beams were constructed. In addition, two post-tensioned slabs were constructed to evaluate the ability of cathodic current to provide corrosion protection to anchorages and tendons encased in metal or plastic conduits. Cathodic protection currents were supplied by IR drop-free potential controlled rectifiers. Later in the study, constant-current power supplies were utilized.
