An?ultrasonic pulse velocity (UPV) test?is an?in-situ,?nondestructive?test to check the quality of?concrete?and natural rocks. In this test, the strength and quality of concrete or rock is assessed by measuring the velocity of an?ultrasonic pulse?passing through a concrete structure or natural rock formation.
This test is conducted by passing a pulse of ultrasonic through concrete to be tested and measuring the time taken by pulse to get through the structure. Higher velocities indicate good quality and continuity of the material, while slower velocities may indicate concrete with many cracks or voids.
Ultrasonic testing equipment includes a pulse generation circuit, consisting of electronic circuit for generating pulses and a transducer for transforming electronic pulse into mechanical pulse having an oscillation frequency in range of 40 kHz to 50 kHz, and a pulse reception circuit that receives the signal. Our team have varied experience in conducting UPV Test.
