Abstract
A study of the influence of fracture initiation on the resistivity of mineral building materials was preceded by an investigation into the electrical and electrochemical processes that could interfere with geo-electrical D/C measurements. The phenomena being discussed are the self 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.
Résumé
Une étude de l'influence de l'initiation de la rupture sur la résistivité électrique des matériaux de construction minéraux fut précédée par une investigation sur les processus électriques et électrochimiques qui peuvent interférer avec les mesures géo-électriques en courant continu. Les phénomènes en cours de discussion concement les potentiels propres, les potentiels de contact, la polarisation, les effets de capillarité et de diffusion, les problèmes de transition et finalement les courants de fuite. Pour des problèmes liés à ces phénomènes, des solutions pratiques ont été développées et sont présentées dans cet article.
