Abstract
The attenuation and dispersion of stress waves in multi-phase materials such as granite, paste, mortar and concrete were evaluated by the point-source/point-receiver technique. Glass capillary breaking and a calibrated pin-type transducer were employed as a point source and point receiver, respectively. The frequency dependence of the attenuation and dispersion in the multi-phase materials was obtained by a single measurement and Fourier analysis. Mortar and paste were found to be less attenuative and dispersive than granite and concrete.
