Electrically Conductive Concrete: A Laboratory Study

Report No: 88-R8

Published in 1987

About the report:

In the cathodic protection of existing reinforced concrete bridge decks, there is a need for a simple secondary-anode system to facilitate the distribution of direct current over the structure being protected. It is believed that a durable, electrically conductive concrete can fill this need by serving both as an overlay and a secondary-anode system. In pursuit of such a system, three relatively conductive concrete mixtures were examined. Two of these mixtures contained carbon fibers alone, whereas the third contained carbon fibers and carbon black. Comparisons with some physical, mechanical, and electrical properties of a control mixture indicated that a conductive mixture containing fibers alone can be readily designed to be sufficiently durable and conductive to satisfy the need.
