Investigation of interfacial losses in concrete with laser ultrasonics
This paper explores some of the potential advantages of laser ultrasonics for the nondestructive characterization of concrete by investigating losses through concrete interfaces. Specific conclusions of this research are: (1) It is possible to optically generate and detect ultrasound in concrete. (2) The frequency content of these ultrasonic waveforms is dependent upon propagation distance. (3) Aggregate size is not the critical factor in determining the frequency content of an ultrasonic waveform. (4) Greater losses exist than those that are predicted by a simple one-dimensional model.
