Increasing attention has been focused in development of sacrificial anode cathodic protection control of steel in atmospherically exposed concrete. recent years upon systems for corrosion While effectiveness of
this type of cathodic protection can be assessed by depolarization testing and perhapa other techniques, no method presently exists for analytically
characterizing the relative influence of various system and cell
parameters. Of particular interest is the electrochemical behavior of the anode, since its characteristics are generally rate controlling. In view of this, a procedure has been developed in terms of relevant electrochemical terms which permits cathodic polarization of embedded steel in concrete to be quantitatively characterized and for the role of different system variables to be identified. Utility of the method is demonstrated in terms of reported data from laboratory tests and from field structures.
