Book excerpt: A low-cost method for galvanic cathodic protection of reinforcing steel in concrete was examined. In this method, arc-sprayed zinc is deposited on the external concrete surface of steel-reinforced marine substructure bridge components, which are normally subject to corrosion of the reinforcement as a result of chloride ion contamination of the concrete. The concrete cover of corrosion-damaged substructure components is removed, exposing the reinforcing steel. After sandblasting, the zinc is arc-sprayed over the exposed steel and surrounding concrete, creating a 1/2 mm thick galvanic anode, which is in electronic contact with the steel and in electrolytic contact with the water in the concrete pores. In this investigation, the ability of the system to deliver protective current was examined by experiments in the laboratory and at field installations at bridges in the Florida Keys.

Book excerpt: 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.

This book was released on 1996 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sprayed zinc galvanic anodes have shown promise as low-cost alternatives to simple gunite repair or even impressed current systems for corrosion-damaged marine substructure of bridges. Because the anodes are permanently connected to the rebar assembly at many points, it is not normally possible to deenergize the anode for measurement of steel polarization and current delivery. Field performance of these systems has been monitored with short embedded rebar probes fitted with external switchable connections. This has allowed for current density, depolarization decay, and polarized potential measurements as a function of time. The anode current delivery has also been measured with isolated cutout anode regions "windows", and in one case with a specially designed, fully disconnectable anode. The results of the different means of evaluating system performance over several years are compared for various field installations in Florida. The relative merits of the monitoring methods and the information they provide on the corrosion condition of the steel are analyzed.

Available in PDF, EPUB and Kindle. Book excerpt: Corrosion of Steel in Concrete provides information on corrosion of steel in atmospherically exposed concrete structures and serves as a guide for those designing, constructing and maintaining buildings, bridges and all reinforced concrete structures. This new edition incorporates the new European standards as well as USA and other international standards. It also covers developments in galvanic and impressed current cathodic protection, new electrochemical techniques such as electro-osmosis, and stainless steel clad reinforcing bars. 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 structures in corrosive environments and it is therefore essential to address the problems that result. This is a book to educates about and forms a guide to the problems of corrosion, its causes and how to find solutions.

Book excerpt: Concrete is an inherently complex material to produce and an even more complex material to repair. With growing pressure to maintain the built environment, and not simply to demolish and rebuild, the need to repair concrete buildings and other structures is increasing and is expected to become of greater importance in the future. This straightforward book serves as a practical guide to engineers on the processes to be followed in commissioning a concrete repair. It stresses the need to fully understand the cause, extent and location of the problem, by appropriate insitu and laboratory testing. And it outlines the steps to a successful repair. It includes sections on the different repair techniques, giving good practical advice as to where and when to use them, and the warns of the pitfalls of their incorrect use. It also includes an up-to-date guide on the current standards for repair, and provides a good bibliography on other sources of information and books on the various techniques.

Book excerpt: 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.
