Download or read book A Slotted Cathodic Protection System for Bridge Decks written by Gerardo G. Clemeña and published by . This book was released on 1985 with total page 31 pages. Available in PDF, EPUB and Kindle. Book excerpt: A non-overlay, slotted cathodic protection system was installed two years ago on a concrete bridge deck in Virginia. The design, installation, and operation of this system are fairly straightforward. A protective current density of 1.6 mA/ft2 (17 mA/m2) as determined by E-log I curves has been applied constantly on the deck. Various tests have shown that polarization of the structure has been achieved. After more than 18 months in service, the various components of this system appeared to be in good condition.
Download or read book Field Inspection Guide for Bridge Deck Cathodic Protection written by and published by . This book was released on 1988 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: "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

This book was released on 1993 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 book was released on 1985 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Cathodic Protection for Reinforced Concrete Structures written by Paul M. Chess and published by CRC Press. This book was released on 2018-10-12 with total page 122 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Corrosion and Cathodic Protection of Reinforcing Steel in Concrete Bridge Decks written by John E. Grady and published by . This book was released on 1985* with total page 33 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report discusses design and installation of an experimental cathodic protection (CP) system on an existing corrosion-damaged concrete bridge deck. The experimental CP system was installed on an existing three-span concrete deck using platinized primary anodes and secondary anodes of carbon filaments placed in sawed slots, and backfilled with conductive polymer grout. The anodes and rebars (now cathodes) were connected to a DC rectifier-controller that maintains a preset potential level. An appendix containing specifications specially written for the experimental cathodic protection system described in this report is available to interested readers on request as a separate publication.

This book was released on 1999 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: Bridge deck deterioration due to corrosive effect of deicers on reinforcing steel is a major problem facing many agencies. Cathodic protection is one method used to prevent reinforcing steel corrosion. The application of a direct current to the embedded reinforcing steel and a sacrificial anode protects the steel from corrosion. This 1992 project involved placing an Elgard Titanium Anode Mesh Cathodic Protection System on a bridge deck. The anode was fastened to the deck after the Class A repair-work and the overlay was placed using the Iowa Low Slump Dense Concrete System. The system was set up initially at 1 mA/sq ft.
