Non Destructive Test - Ultrasonic Pulse Velocity Test
Ultrasonic Pulse Velocity Tests
Application:
These tests are primarily done to establish:
• The homogeneity of concrete
• Ppresence of cracks, voids and other imperfections
• Changes in quality of concrete over time
• This test does not establish compression strength
of tested concrete
UPV Tests are done in accordance with Indian standards
IS: 13311 (Part 1)
Procedure:
• The concrete surface where probes are to be applied is cleaned properly.
• Grease is applied on the test surfaces
• The probes are pressed on the surface of the structural element to remove air gaps.
• Distance between the two probes is noted.
• Read time taken for the ultrasonic pulse from the instrument.
• Calculate Velocity = distance / time
Pulse velocity by cross probing Concrete Quality Grading
1 Above 4.5 km/s Excellent
2 3.5 km/s to 4.5 km/s Good
3 3.0 km/s to 3.5 km/s Medium
4 Below 3.0 km/s Doubtful
