Electrical resistivity is a property that indicates the material’s resistance to the passage of electrical charges at a defined temperature. Concrete is a porous material and the porosity in concrete consists of a system of nano- and microscopic pores, interconnected at different degrees. In concrete, resistivity is directly proportional to the resistivity of the pore solution, and inversely proportional to the volume and connectivity of the pores.
