Abstract
A study of the influence of fracture initiation on the resistivity of mineral building materials was preceded by an investigation into the e lectrical and electrochemical processes that could interfere with geo- electrical D/C measurements. The phenomena being discussed are the sel f potentials, the contact potentials, the polarization, diffusion and capillarity effects, the transition problems, and finally the leakage currents. Practical solutions developed for problems related to these phenomena are discussed in this paper.
