【 摘 要 】

The paper presents the research findings obtained as a result of the ultrasonic nondestructive testing of flaw detection in one-sided access confined concrete. The ultrasonic nondestructive testing is applied to detect the size and location of internal defects in confined concrete that allows the accurate taking cores and their mechanical testing. Tomographic images of the scanned internal structure are given herein as well as the results of compressive strength testing of cores taken from defective portions of the concrete one-sided access construction.
