The heterogeneity of concrete and the severe wave-microstructure interactions render the thorough investigation of ultrasonic wave propagation imperative, especially when the latter is used for material characterization and quality control. In this study, parallel to the advanced ultrasonic experiments, numerical simulations are additionally performed offering faster, reliable and accurate solutions at low cost, as well as flexibility on the design and measured properties. Cement pastes and mortars are investigated while the observed dispersive and attenuative trends are further explained with scattering theories reinforcing the characterization potential.
