Book Description
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.

Book Description
Cathodic protection is accepted as a repair option for steel-reinforced structures that are undergoing corrosion caused by the presence of chlorides. The Strategic Highway Research Program (SHRP) issued a contract on cathodic protection of reinforced concrete bridge elements. The objective of part of that contract was to investigate the feasibility of improved and simplified control criteria. To this end, corrosion rates of steel in a concrete environment were measured relative to many factors, and then, data were used to appraise control criteria. This technical alert presents the results and recommendations based on that part of the work.

Book Description
This report describes the evolution of cathodic protection of reinforced concrete bridges and its current state-of-the-art. It discusses how cathodic protection works, and the effectiveness of the technique. An extensive history of cathodic protection of reinforced concrete is included that covers all aspects of completed projects. There are sections on condition surveys, remedial action, anode systems, design aspects, operation and maintenance, and research and development needs. All of the various types of anode systems are characterized in detail as they have been designed and constructed. The ancillary equipment common to all systems such as power supplies and monitoring equipment are reviewed. Research and development needs are addressed to bring to light the essential research work that is required to further the development and use of cathodic protection of reinforced concrete structures.

Book Description
Cathodic protection of reinforced concrete structures is a technique for rescuing corrosion damaged structures and, in certain instances, preventing them from corroding in the first place, and its use is growing. This book is for specialist contractors, large consultants and owners of corrosion damaged structures, and looks at international experience with this technique. It examines why corrosion is occurring, the differences in the application of CP with the stark dichotomy in its success and failure, and finally ways in which its performance can be improved on future installations. Information is valuable, as the success or failure of the CP system has a marked effect on the service life of the structure.

Book Description
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

Book Description
While cathodic protection effectively reduces or stops ongoing corrosion of reinforcing steel in concrete, applicability of this technology to prestressed members has been limited because of concerns regarding possible bond loss and hydrogen embrittlement. Within this context, the present research was intended as a comprehensive, multifaceted undertaking to elevate the understanding of prestressed concrete cathodic protection to the same level as for reinforced concrete. The program involved four components: (1) constant extension rate testing (CERT) of precorroded tendon wires, (2) cathodic overprotection of precorroded, pretensioned beams with evaluation for hydrogen embrittlement susceptibility, (3) concrete block pull-out tests to determine any effect of cathodic protection on the tendon-to-concrete bond, and (4) evaluation of a commercially available remote monitoring and control hardware and software system for application to prestressed concrete cathodic protection.
