TECHNICAL ALERT: CRITERIA FOR THE CATHODIC PROTECTION OF REINFORCED CONCRETE BRIDGE ELEMENTS

Cathodic protection is accepted as a repair option for steel-reinforced structures that are undergoing corrosion caused by the presence of chlorides. Several different criteria (tests) have been suggested for use with concrete structures, and many are in use today. Due to the number and complexity of tests, much confusion and disagreement exists regarding the use of such criteria. The Strategic Highway Research Program (SHRP) issued a contract on cathodic protection of reinforced concrete bridge elements. The objective of part of that contract was to investigate the feasibility of improved and simplified control criteria. To this end, corrosion rates of steel in a concrete environment were measured relative to many factors, and then, data were used to appraise control criteria. This technical alert presents the results and recommendations based on that part of the work.
