| Résumé : | This chapter deals with ultrasonic testing of concrete using embedded piezoelectric transducers for crack monitoring. Compared to traditional ultrasonic transducers, using embedded transducers improves the efficiency and the reproducibility of ultrasonic tests and allows performing measurements in inaccessible places when the structure is in service. The evolution of the crack formation can be evaluated by computing in real-time a damage indicator based on the recorded ultrasonic signals. This technology is demonstrated on a three point bending test on a reinforced concrete beam. |
