ABSTRACT: Ultrasonic testing is a non invasive surveying technique suggested for concrete quality control.
European standards concerning the determination of ultrasonic velocity in concrete do not give exhaustive
suggestion about the frequencycharacteristics of the transducers to be used in the test. Commercial measurements
systems offer several types of transducers
