The equipment for non-destructive ultrasonic testing of concrete can be subdivided in three major groups:
-
Ultrasonic pulse-echo tomography systems
Ultrasonic tomography imaging can be used to localize structural elements (reinforcement, tendon ducts, pipes) and detect material voids (honeycombs, delaminations, cracks and cavities).
-
Ultrasonic pulse velocity testers (UPVT)
Ultrasonic pulse velocity (UPV) is the established and easy-to-use application for in-situ evaluation of compressive strength by means of ultrasound.
-
Ultrasonic pulse-echo flaw detectors
Ultrasonic pulse-echo testing is an affordable technique for thickness measurement and flaw detection in concrete and structural metallic elements, such as anchor bolts
