This work investigated the feasibility of improved and simplified control criteria for cathodic protection of concrete structures. Corrosion rates of steel were established in a simulated concrete environment as a function of chloride contamination, pH, temperature and cathodic protection current. mathematical models were developed to establish concentration profiles which develop as a result of cathodic protection current, and to study current distributions which result from geometric factors. These studies are combined to develop improved and simplified current-based control criteria. Long-term effects of cathodic protection current on concrete and aggregate near the steel and the anode were also investigated.

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

Whatever his name or alias at the moment—Henry McCarty, Henry Antrim, Kid Antrim, Billy Bonney—people always called him the Kid. Not until his final month did anyone call him Billy the Kid. Newspapers pictured him as a king of outlaws; and his highly publicized capture, trial, escape, and end fixed his image in the public mind for all time. He was only twenty-one years old when a bullet from Sheriff Pat Garett’s six-shooter killed him on July 14, 1881. Within a year Billy the Kid became the subject of five dime-novel “biographies” as well as Garett’s ghost-written account, and that was just the beginning. Robert M. Utley does what countless books, movies, television shows, musical compositions, and paintings have failed to do: he successfully strips off the veneer of legendry to expose the reality of Billy the Kid. Using previously untapped sources, he presents an engrossing story—the most complete and accurate ever—of a youthful hoodlum and sometime killer who found his calling in New Mexico’s bloody power struggle known as the Lincoln County War. In unmasking the legend Utley also tells us much about our heritage of frontier vigilantism and violence.

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.

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.

The corrosion of reinforcing steel in concrete is a major problem facing civil engineers and surveyors throughout the world today. There will always be a need to build stuctures in corrosive environments and it is therefore essential to address the problems that result. Corrosion of Steel in Concrete provides information on corrosion of steel in at

Corrosion of Steel in Concrete: Understanding, Investigation and Repair is a guide for designing, constructing and maintaining reinforced concrete structures, such as buildings and bridges which are subject to reinforcement corrosion. It presents the basics of theory and practice in steel corrosion in concrete and reviews the latest research and developments, such as progress on measuring the corrosion threshold for chloride-induced corrosion. This third edition compares the currently proliferating major national and international standards and guidance documents. New developments are considered, such as hybrid anodes for electrochemical treatment and the latest research and developments in assessment, such as the use of ground penetrating radar to measure the chloride content of the concrete cover. It overhauls coverage of electrochemical repair and rehabilitation techniques and outlines recent innovations in structural repair and construction and investigates their implications for durability. The book is ideal for practitioners and graduate students in structural engineering and concrete technology.

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.
