This is the interim report for a study to evaluate the use of sacrificial cathodic protection for reinforced and prestressed concrete bridge members. Cathodic protection (CP) using impressed current is an accepted and common method used to provide corrosion protection to steel in concrete. This study examined the performance of existing sacrificial alloys in different environments for sacrificial CP, and developed new sacrificial alloys for protecting steel in concrete. The study consisted of both laboratory and field tasks. The first task consisted of tests to identify suitable environments for sacrificial alloys. In the second task, two bridges with a zinc sacrificial anode in the Florida Keys were inspected and tested. Data on anode current output, anode and cathode potential, and anode and cathode depolarization were recorded.

Revised and updated, this second edition of Cathodic Protection of Steel in Concrete and Masonry covers both reinforced concrete and masonry structures, describes in detail the overall design factors involved in cathodic protection (CP), and also provides a theoretical basis for why it works. It refers to the new European standard EN 12696 for cath

The current needs and interests of the cathodic protection community are reflected in this volume which is designed to be a manual for the successful application of cathodic protection techniques. It has grown from the proceedings of the Second International Conference on Cathode Protection Theory and Practice, and follows on from Cathodic Protection Theory and Practice. This book should be a useful reference for practitioners and advanced students alike, organized around the practical applications of cathodic protection theory. It presents comprehensive coverage which reflects international best practice.

This is the final report in a study to demonstrate the feasibility of using cathodic protection (CP) on concrete bridge structures containing prestressed steel. The interim report, FHWA-RD-95-032, has more details on the installation of selected CP systems. Past laboratory and test yard studies had indicated that overprotection could result in the evolution of atomic hydrogen and the embrittlement of prestressing steel. Systems utilizing catalyzed titanium mesh, conductive rubber, and arc-sprayed zinc anodes were installed on prestressed pilings and girders of the Howard Frankland Bridge in Tampa, Florida; and systems using flame-sprayed zinc and conductive paint anodes were installed on the soffit of prestressed box beams of the Abbey Road and West 130th Street bridges near Cleveland, Ohio. For most of the components tested, CP was achieved safely and reliably without reaching conditions that could result in embrittlement of prestressed steel.
