Non destructive evaluation of damage and cracks in reinforced concrete by electrical resistivity measurement
The article presents prospective works on the resistivity measurement for on site concrete damage characterization, in the frame of the non destructive evaluation methods. The electrical technique, adapted from geophysical science, is easy to use and adapted to on site constrains. Still in development, electrical resistivity presents an interesting ability to characterize concrete damage and more particularly its cracks. Besides cracks detection and sitting, presented results prove the workable sensitivity of electrical resistivity measurements to their moisture degree. Furthermore, they show the ability to assess cracks depth, and the sensitivity to its filling (and indirectly to its opening). All these factors are of major importance for structural and durability assessment. Numerical and experimental works show disturbance of apparent resistivity right to cracks, for crack in various conditions. Results have to be completed with new test sessions, but they represent a basis for further works. The other way for the research, still engaged, is the coupling of electrical resistivity with acoustical method (the second NDT method sensitive to cracks depth, and in development too) to improve the diagnosis. Anyway, electrical method represents a technique allowing to help engineers, giving an original response to their problems of assessing damage degree of structures.
