This book was released on 1995. Evaluations of Sacrificial Anodes for Cathodic Protection of Reinforced Concrete Bridge Decks available in PDF, EPUB and Kindle. 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.
