Pulse Velocity - an overview ScienceDirect Topics

The ultrasonic pulse velocity (UPV) measurement can be utilized for the determination of concrete uniformity, cracks or voids' presence, changes in properties with time. As the amount of DOTP in the concrete increases, the ultrasonic pulse velocity of the concrete decreases. It can be said that this is due to the porous structure of DOTP-reinforced concrete (Şimşek et al., 2018).
