Atypical Applications of Ultrasonic Method in Testing of Concrete Structures

摘要

This paper presents atypical applications of the ultrasonic method in the in situ testing of concrete in structures by means of exponential heads. In typical applications of the ultrasonic method, the large contact surface area of flat measuring heads (20-50 mm in diameter) sometimes makes it difficult to carry out such measurements on the investigated element. If detailed information about the tested material along its thickness is to be obtained, e.g. in order to determine the depth of an improperly made floor surface concrete layer, then exponential heads should be used, which is described in this paper.
