Book Description
Laboratory evaluations were carried out on a series of anode materials, including aluminum, magnesium, and zinc alloys. Anode/steel couples were placed in simulated concrete environments consisting of sealed containers filled with silica sand treated with a mixed alkali-chloride solution. Measurements of current flow, circuit resistance, potential, and depolarization were made over a period of 18 weeks. Based on results obtained, aluminum and zinc anodes were found to hold the most promise for use as galvanic anodes in reinforced concrete bridge decks. A series of reinforced concrete test slabs were produced for evaluation of the candidate materials. Normal-weight structural concrete, structural lightweight concrete, free-draining concrete, and free-draining latex-modified concrete overlays were placed over the anodes to serve as riding surfaces. Performance of the cathodic protection (CP) systems was evaluated using current flow and depolarization techniques.

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.

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.
