Abstract: Assessing the concrete properties from very early age is one of the main concerns for contractors. Embedding permanently specific piezoelectric transducers into the structure allows to monitor in real time to evolution of concrete properties which can be extracted from ultrasonic measurements. In the present research, a non-reinforced concrete beam in which embedded piezoelectric transducers are embedded is monitored from very early age to crack appearance. The monitoring system is based on low voltage short pulses excitations signals recorded at high rate (more than 70 ultrasonic measurements per second). The method has demonstrated its great ability for tracking on-line concrete behavior.
