Abstract
This study computes appropriate geometrical factors for the four-probe method to accurately evaluate the electrical resistivity of concrete specimens. The geometrical factors were obtained using the potential and current distributions in the specimens calculated by finite element method analyses adopting the Laplace equation, assuming a probe spacing of 1–9 cm for several types of specimens. Furthermore, a thorough discussion of the current distribution and the variation in the measurement results indicated that the probe spacing must be as wide as possible to evaluate the mean value of the electrical resistivity.
