Abstract: To propose a new tool to buildings managers in their need for damage assessment of structure, electrical resistivity measurement is developed. The method presents interest (and not yet) exploited sensitivity to damage of concrete. The development of this method, still in progress, is lead to ensure engineers the control of obtained information. Works are then leaded to accurate the technique either by the improvement of on site measurements, or through post processing of measurements.
After the presentation of the technique, measurement parameters are listed. Works aiming at the correction of disturbances linked to structural parameters are discussed: boundaries effects and rebar presence. Numerical results are validated by measurements on real structure. And the capacity of electrical resistivity method to be corrected is shown, to finally obtain results depending only on the material condition.
