Effect of Inhomogeneity Parameters on Wave Propagation in Cementitious Material

The relationship between cementitious material inhomogeneity and stress wave parameters is investigated in this study through parameter measurement of ultrasonic waves through transmission measurements. Even more highlighted velocity dispersion and attenuation for specific frequency bands can result from the presence of damage in the form of cracks, except from this type of material's inherent inhomogeneity. During concrete casting, therefore, different crack-like, film-shaped particle contents are included to evaluate distributed damage contribution in the observed wave parameters. Experiments are carried out using both high- and low-frequency sensors whose frequency range also covers those used for in-place application.
