T/JSJTQX 51-2024 (English Version)

Scope: Technical regulations for array ultrasonic detection of internal defects in cement concrete Main technical contents: Ultrasonic nondestructive testing is an important technical means to diagnose the health status of cement concrete structures. Through array ultrasonic emission and reception, the propagation information of the internal wave field of concrete is obtained, and with the help of mathematical models, it is inverted into the corresponding physical value matrix, and finally converted into an image of the internal structure of concrete. This method can realize the intuitive judgment and quantitative analysis of internal defects in concrete, and completely avoid the damage to concrete caused by detection operations. This document specifies the terms and definitions, general provisions, test preparation, testing and test reports for the detection of concrete defects by array ultrasonic method, which is of great significance to improving the standardization and normalization level of the application of array ultrasonic method in highway engineering.
