The study of ultrasonic pulse velocity on plain and reinforced damaged concrete
MATEC Web of Conferences, 2018 An ultrasonic pulse velocity (UPV) test is often applied to determine the quality of concrete structures. It is well known that there are several factors which can influence the reading of ultrasonic velocity in concrete.

Predicting the Compressive Strength of Concrete By Ultrasonic Pulse Velocity
IOP Conference Series: Materials Science and Engineering, 2021 Abstract The key resolution of non-destructive methods applied to concrete structures is to offer a suitable estimate of the quality of the material. One of the modern methods used in the test of concrete strength is the non-destructive testing applying the ultrasonic pulse velocity (UPV).
