This technical report presents evaluation techniques which can potentially be used to complement performance criteria of international standards, especially if the criteria cannot be employed to evaluate the effectiveness of cathodic protection and corrosion control techniques applied to existing reinforced concrete structures, including atmospherically exposed, buried, and submerged structures.

This report:

•            Identifies and expands on criteria in international standards and specifications that define effective cathodic protection;
•            Provides background to alternative evaluation techniques;
•            Identifies new and existing techniques and methods for assessing the effectiveness of cathodic protection; and
•            Provides considerations for planning work based on the current state of the art.

This report is intended to be useful to architects, structural engineers, architectural conservators, and consulting engineers/contractors who are engaged in refurbishing steel-reinforced concrete structures and buildings.
