This paper summarizes the results of research aimed at assessing cracks in reinforced concrete structures using embedded ultrasonic sensors. The diffuse ultrasonic waves were considered to evaluate the health status of the tested structures. There are different algorithms used to detect cracks in the structure. but most studies have been performed on benchmark reinforced concrete (RC)... https://www.roneverhart.com/Wilson-EZ-Gear-Catcher-s-Kit-Navy-Small-Medium/
