Electrically conductive polymer concrete overlays
The development of a built up, electrically conductive polymer concrete overlay and a premixed, electrically conductive polymer concrete mortar for use on bridge decks and other concrete members, in conjunction with cathodic protection systems, is reported. The research program was divided into two phases. The emphasis of the work performed in phase one was directed towards the evaluation of the 18 commercially available resin systems and the 16 conductive filler systems selected for consideration. Basic studies were also performed to evaluate various parameters affecting the electrical resistivity properties of both the built up overlay and premixed mortar systems. In phase two, extensive evaluation of the physical and mechanical properties of the most promising overlay and premixed mortar systems were performed. In addition, the performance characteristics of the selected overlay systems, when incorporated into active cathodic protection systems, were evaluated. On the basis of the test results reported, recommendations were made regarding the further development and use of both the built up, electrically conductive overlay and the premixed, electrically conductive mortar systems (a).
