The assessment of concrete quality by ultrasonic pulse velocity

open access: yesJournal of Science and Technology in Civil Engineering (STCE) - NUCE, 2018
In the present study, the uniformity and potential internal defects of concrete elements in situ were assessed by using Ultrasonic Pulse Velocity (UPV) testing method according to TCVN 9357:2012. Thirteen cross beams with dimension of 4.8 x 1.5 x 1.5 m3 were selected to measure the pulse velocity. Three cross beams were used to check potential internal
