This paper constitutes a literature review of the electrical resistivity of concrete. Electrical resistivity is an important consideration in such applications as cathodic protection systems and hospital operating room floors, where low resistivities are required and electrically powered rapid transit lines, where high resistivities are needed. Electrical resistivity is also important where reinforced concrete will be exposed to corrosive conditions, as corrosion currents will flow more easily in concrete having low resistivity. Information on the effects of concrete materials and mix designs on electrical resistivity are presented in this paper. The effects of such variables as temperature, and moisture content are also discussed. Data taken from the literature is presented in tabular and graphical form. Over 50 references to the published literature are also included.
