Abstract

In this paper, volume fraction and size of aggregates in highly dispersive materials have been estimated using ultrasonic techniques. Estimations were made by obtaining the best fit between experimental scattering attenuation and theoretical predictions obtained from an N-phase extension of the dynamic generalized self-consistent method (DGSCM) proposed by Yang [J. Appl. Mech. 70 (2003) 575]. Furthermore, a time-frequency procedure has been designed to estimate frequency-dependent scattering attenuation from experimental measures. The research was conducted with several cement mortar specimens made by taking into account different aggregate-to-cement ratio and water-to-cement ratio. Estimations of both size and volume fraction, were made and good agreements was found between experimental attenuation curves and theoretical predictions.
