Question 52
ARMCQ1 markNeeds review
An Ultrasonic Pulse Velocity (UPV) test was done on a hardened concrete element using a direct transmission method as per IS 516 (Part 5/Section 1): 2018. The distance between the transducer and receiver was 600 mm. The time taken for the induced wave to travel this distance is measured as 0.18 milliseconds. Based on the following Table, the concrete quality grading is __________.
Velocity (km/s) – cross probing | Concrete quality grading |
|---|---|
Above 4.4 | Excellent |
3.75 – 4.4 | Good |
3.0 – 3.75 | Doubtful |
Less than 3.0 | Poor |
