Methods of Non-Destructive Testing of Concrete Following are different methods of NDT on concrete: Penetration method Rebound hammer method Pull out test method Ultrasonic pulse velocity method ...

This time represents double the distance between the range finder and the target. The final step is to use the parameter math rescale function to multiply the time by one-half of the pulse velocity.

In the first article low ultrasonic frequencies must be used in non-destructive testing of heterogeneous materials, such as plain and reinforced concrete, cast iron or timber. When frequencies are low ...

Also, a material’s ultrasonic pulse velocity (UPV) is affected by various variables, and it is difficult to study their combined effect experimentally. This research used machine learning to assess ...
