Ultrasonic Pulse Velocity Test

It is a non-destructive test, generally applied to concrete and rocks in order to asses their quality based on the velocity at which an ultrasonic pulse travels through the element. High velocities imply high quality and continuity of the element, while low velocities indicate a lower quality, cracks or other anomalies such as honeycombed concrete, voids, etc.

It’s mainly applied to:

Example application to verify the quality and homogeneity among different columns and beams on a construction site. The image below shows the record of the ultrasonic pulse, its arrival time and its velocity in the concrete.
