Thank you for your comment. Below is a description of the direct and indirect transmission methods in the UPV test, as demonstrated in this video. Please feel free to add your thoughts by highlighting specific points, as this will be helpful for everyone. - Direct transmission is defined as the propagation of ultrasonic stress waves along a straight-line path between the opposite surfaces of a specimen. - Indirect, or surface, transmission is defined as the propagation of ultrasonic stress waves between points that are located on the same sur face of the material.
@@constructionengineeringtip6028 I appreciate the fact that you acknowledged my comment but I think it would be much appreciated if you actually put the correction in the video or most preferably a new one for the sake of those that may not have prior knowledge and would want to learn for the first time.
can we get result for grade/strength of concrete by this NDT TEST MY HOD told me that the strenth of the concrete is inversely proportional to the velocity of the ultrasonic rays
The description of "semi-direct" and "direct" transmission is wrong. Please correct so that you don't mislead people.
Thank you for your comment.

That’s interesting. I don’t have the results with me right now. When I get it I will share it with you. Sorry for the late reply.
