Guide Specification for Cathodic Protection of Concrete Bridge Decks
Author: Cathodic Protection of Concrete Bridges
Author: Jack E. BennettPublisher: Strategic Highway Research Program (Shrp)
ISBN:
Category : Technology & Engineering
Languages : en
Pages : 316
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.
Field Inspection Guide for Bridge Deck Cathodic Protection

Category : Concrete bridges
Languages : en
Pages : 64
Book Description
"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

Book Description
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.

Corrosion and Cathodic Protection of Reinforcing Steel in Concrete Bridge Decks
Author: John E. GradyPublisher:
ISBN:
Category : Bridges
Languages : en
Pages : 33
Book Description
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.

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

Author: Installation and Operational Comparison of Five Bridge Deck Cathodic Protection Systems

ISBN:
Category : Bridges, Concrete

Pages : 180
Book Description
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.
