Electrode Configurations for Resistivity Measurements on Concrete

This study evaluated saturated concrete specimen electrical resistance (hence resistivity) through two- and four-electrode arrangements using external plate-electrodes, embedded rod-electrodes, and combinations thereof. A fixed 1 KHz frequency was mainly used to obtain measurements. Results showed that higher resistivity values were given by the two-electrode external plate measurement system than the four-electrode system; however, study, in terms of complex impedance over a 1 to 10 MHz frequency range, of electrical response revealed that a spurious resistance attributed to the sponge-sample interface was introduced through the sponge-contacting system used in the two-electrode method.
