Method and apparatus for non-destructive testing of concrete components.

摘要

Non-destructive testing method for concrete components comprising a mould (1); ultrasonic transducers (E, R) fixed to the mould, a transducer-transmitter (E) being placed on a wall of the mould facing another wall supporting transducer-receivers (R1, R2, R3); a fixing device associated with each transducer in order to maintain it against one of the walls of the mould (1); an electronic assembly (4) connected to each of the transducers and intended to determine the propagation time of the waves propagating in the concrete between the transducer-transmitter (E) and the transducer-receivers (R1, R2, R3); a programmable computer whose input is connected to the electronic assembly (4) and whose output is connected to a display device (8) and which is intended to process the said propagation time of the waves in order to continuously provide the variation in the characteristics of the concrete component. <IMAGE>
