A systematic review of ultrasonic techniques for defects detection in construction and building materials

Ultrasound is considered as an effective nondestructive testing method. This review paper discusses the potential of ultrasonic techniques for defect detection and fractures in construction and building materials, which explains the basic principles of ultrasonic approaches and their widespread application in non-destructive testing (NDT). The paper also summarizes the benefits of ultrasonic computerized tomography (UCT), highlighting its high resolution, stability, and low radiation compared to other techniques. Additionally, it introduces an enhanced usage of UCT that involves the flexible arrangement of transmitting and receiving probes in ultrasonic apparatus to improve the accuracy of UCT signals.
