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

This report compares the application and testing of the following five independent cathodic protection (CP) systems installed on three reinforced concrete bridge decks: 1) Coke Breeze; 2) Metallized Zinc; 3) Raychem "Ferex 100"; 4) Eltech "Elgard 210"; 5) Conductive Polymer. All five CP systems were installed under a single contract and work was performed by the same contractor during the summer of 1988. Construction methods, materials, and the difficulties encountered in installing each type of system are included. During the six year study period (November 1988 to November 1994), all five systems were monitored regularly. Parameters monitored were driving voltage, current density, and polarization decay. The efficiency of providing corrosion protection for each system based on these parameters is compared.

This document provides explanation, guidance, and direction concerning cathodic protection of concrete bridge elements to the highway engineer who wants to incorporate cathodic protection in a bridge project. The manual which provides background information on corrosion fundamentals, is divided into 3 parts: design, construction, and operation and maintenance. An appendix provides standard specifications for cathodic protection systems for both decks and substructures. The document is intended to be a useful reference for engineers who design and prepare specifications or who oversee turnkey operations.

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.

The conference focused on the major problem facing highway and bridge engineers: deterioration of concrete bridge decks caused by corrosion of the reinforcing steel. The conference was aimed primarily at giving bridge owners and engineers an understanding of cathodic protection as the only means to stop corrosion on bridge decks.
