Title: Electrochemical Behavior of Steel in Concrete
Author(s): D. A. Hausmann
Publication: Journal Proceedings
Appears on pages(s): 171-188
Abstract:The protective mechanism by which concrete prevents the corrosion of encased steel is reviewed. The effects of im- pressed voltages on the concrete-steel system are described and related to chemical reactions occurring at the steel -- surface. An important distinction is made between the ohmic resistance of concrete and the apparent resistance offered by polarization effects which control both current collection deand discharge over a wide range of operating potentials. Criteria are suggested for the practical application of ex-cathodic protection to reinforced concrete structures. A cathodic protection experiment with mortar-lined-coated steel pipe is reported.
