Title: ELECTROCHEMICAL REMOVAL OF CHLORIDE IONS FROM REINFORCED CONCRETE: INITIAL EVALUATION OF THE PIER S19 FIELD TRIAL

Digital Copy: Availability: Find a library where document is available Abstract: The initial evaluation of a commercial process for the electrochemical removal of chloride ions from concrete is reported. A trial was conducted over an 8-week period in 1989 on a section of Pier S19 of the Burlington Skyway. The evaluation included visual examination, corrosion potential, and rate-of-corrosion measurements on the structure, and petrographic examination and measurement of chloride ion profiles on samples removed from the structure. Data up to 13 months after treatment of the concrete are reported. The treatment was successful in moving chloride ions away from the reinforcing steel and in removing a substantial proportion from the concrete without apparent damage to the concrete. The long-term effectiveness of the treatment is the major unknown factor.
