Characterization the Acoustic Impedance of Mortar Using Ultrasonic Technique

To understand the relation between the hardening of cementitious materials and the evolution of the mechanical properties of mortar specimen, we developed an experimental study to evaluate the effect of particles seize of sand and temperature on the evolution of acoustic impedance of mortars specimens. The results obtained indicated that particles of sand seizes was found to have an effect on ultrasound wave in the evolution of acoustic impedance. It was also found that the variation of environment temperature has a significant effect in the evolution of acoustic impedance of mortar.
