Acoustic wave propagation in heterogeneous and dispersive media is a very complex phenomenon, where the phase velocity and attenuation are function of the material microstructure, and becomes frequency-dependent parameters. In this paper, the interaction between ultrasound waves and cement-paste specimens have been analyzed by two multiple scattering models, based on homogenization approach, and experimental data. The experimental phase velocity, attenuation and the dispersion results show good agreement with the theoretical models; the experimental phase velocity and attenuation decrease for higher w/c ratio, as predicted by the theoretical models.
