Leaching of conductive species: Implications to measurements of electrical resistivity [PDF]

open access: yesCement and Concrete Composites, 2017
Electrical tests have been used to characterize the microstructure of porous materials, the measured electrical response being determined by the contribution of the microstructure (porosity and tortuosity) and the electrical properties of the solution (conductivity of the pore solution) inside the pores of the material.
