This article summarizes the non-destructive testing techniques for concrete structures and their importance in evaluating the durability of concrete. With the aging of infrastructure, the demand for rapid and accurate evaluation and maintenance of concrete structures is increasing. Non destructive testing technology is highly valued for its ability to provide accurate evaluations without damaging the structure. The article introduces the main non-destructive testing methods, including ultrasonic testing, electromagnetic wave testing, and radiometric testing, and discusses in detail the application effects of these technologies in practical engineering. The advantages and disadvantages of each technology were also compared and analyzed. In the future, with the development of intelligence, integration, and portability, non-destructive testing technology will further improve detection efficiency and accuracy, and be widely used in long-term monitoring of infrastructure, providing technical support for extending the service life of structures and reducing maintenance costs.
