[0002] With the rapid development of transportation infrastructure construction, especially the rapid popularization of highways and high-speed railways, higher requirements are placed on the construction quality of highway bridges. As the main material of bridge structure, the strength of concrete directly affects the bearing capacity and service life of the bridge. Therefore, in the process of highway bridge construction, accurate detection of concrete strength is particularly important.
