In 1942 [11] it was proved by researches, that the resistivity value of porous material can be determined by the following equation: , (2) where r0 is the water phase resistivity in the concrete, a is the constant depending on the metal structures, m is the integral parameter, related to the pores structure in the material, φ is the proportion of volumetric water saturation of the pores.
There are several methods for measuring the resistivity of materials: disk method with a single external electrode, two-electrode and four-electrode methods.
