"This report is intended as a guide for inspectors who are unfamiliar with the construction procedures used when installing cathodic protection systems on reinforced concrete bridge decks. The text has been divided into sections in an effort to simplify the report and make it easier to locate desired information. The first four sections provide some basic background information about cathodic protection. Section V discusses a general system installation; each of the major components are discussed to provide a basic understanding and act as a checklist during the installation process. Section VI discusses the various types of systems that have been installed, to date. This is not intended to be an all-inclusive manual. Rather, it is to be used as a guide to help overcome some of the most common problems associated with the installation of cathodic protection systems. It is meant to support and supplement good specifications, not replace them"--Page 1

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

Corrosion of reinforcement in concrete bridges has been a major factor in limiting the service life of many such structures. As part of a concerted effort to identify cost-effective options for eliminating corrosion of reinforcement, the application of cathodic prevention was tried in a recently constructed concrete bridge deck. The incorporation of an impressed-current cathodic prevention system in a new concrete bridge deck while it was being constructed was made possible by the use of titanium mesh ribbon anodes coated with mixed-metal oxide. The anodes were spaced 32 cm (13 in.) apart and transversely across the entire bridge deck to allow for the trouble-free placement of the concrete. The system has been operating for almost 2 years with no extraordinary problems. A comparison of the long-term cost of this option with those of other options, such as the use of corrosion-resistant clad bars or stainless steel bars, indicated that this option is not economically favorable.

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.

The Handbook of Environmental Degradation of Materials, Third Edition, explains how to measure, analyze and control environmental degradation for a wide range of industrial materials, including metals, polymers, ceramics, concrete, wood and textiles exposed to environmental factors, such as weather, seawater, and fire. This updated edition divides the material into four new sections, Analysis and Testing, Types of Degradation, Protective Measures and Surface Engineering, then concluding with Case Studies. New chapters include topics on Hydrogen Permeation and Hydrogen Induced Cracking, Weathering of Plastics, the Environmental Degradation of Ceramics and Advanced Materials, Antimicrobial Layers, Coatings, and the Corrosion of Pipes in Drinking Water Systems. Expert contributors to this book provide a wealth of insider knowledge and engineering expertise that complements their explanations and advice. Case Studies from areas such as pipelines, tankers, packaging and chemical processing equipment ensure that the reader understands the practical measures that can be put in place to save money, lives and the environment. - Introduces the reader to the effects of environmental degradation on a wide range of materials, including metals, plastics, concrete, wood and textiles - Describes the kind of degradation that effects each material and how best to protect it - Includes case studies that show how organizations, from small consulting firms, to corporate giants design and manufacture products that are more resistant to environmental effects
