Wave propagation signals for ultrasonic tomography of concrete during splitting

The DataSet contains the results of the mechanical behaviour of a concrete cube with dimensions 70 x 70 x 70 cm3under the splitting test. Three cubes were tested: cube 1 (concrete with polymer fibres), cube 2 (concrete with steel fibres) and cube 3 (plain concrete).
Before and after splitting, wave propagation signals were registered with a sampling frequency of 20 MHz. The excitation was a one-cycle wave packet with a central frequency of 100 kHz. The configuration of transmitters (T1-T12) and receivers (R1-R12) is shown in the figure. The files utilize a comma-separated values (.csv) format and contain wave propagation signals of a length of 5 m. In a single file, the time vector (in ms) and the signals from channels A, B, C, D, E, F and G (in V) can be found.
