Some elements for improving interpretation of concrete electrical resistivity
In the frame of the French ANR project SENSO, several non destructive techniques are tested in the laboratory on numerous concrete slabs. All the concrete slabs have been conditioned with a saturation degree close to natural condition (about 50%). Electrical resistivity measurements have been systematically carried out using different devices adapted to on site works, each of them composed of four probes. The first device involves 4 probes in Wenner linear configuration; the second involves 4 probes in a square configuration. In the first part, the analysis of electrical resistivity method is discussed considering the reliability between the two devices. In the second part, non destructive tests are compared to semi-destructive and destructive evaluation. Based on capo-tests and rebound hammer tests performed on a reduced set of the same samples, the link between electrical results and mechanical tests is discussed. Particular attention is focussed on actual quality of concrete cover layer defined by means of electrical resistivity measurements and their influence on associated mechanical properties of concrete structure. Interest of electrical resistivity measurement (totally non destructive) is studied, highlighted by mechanical information on concrete (used for structural re-assessment of structures).
