Results from an experimental study of ultrasonic, through-transmission, wave propagation on fresh cementitious material are discussed in this paper. The propagation characteristics of different frequency tone-bursts revealed the strong dispersive behavior of this type of materials while using sine-sweep excitation, the attenuation up to about 1 MHz was examined. Sand content and size exercise significant influence on wave parameters while entrapped air bubbles seem to dominate the attenuation at low frequencies since cement paste specimens, containing no sand, exhibit strong attenuation. The possibility of mortar composition characterization within 10 min after mixing is also addressed leading to encouraging results.
