Abstract: This research uses laser ultrasonic techniques to study the effect of aggregate size on the attenuation of Rayleigh surface waves in cement-based materials. The random, multiphase, and heterogeneous nature of cement-based ...

Abstract: This research uses laser ultrasonic techniques to quantify the frequency-dependent attenuation losses of Rayleigh waves in cement-based materials; these materials are heterogeneous in nature, and this heterogeneity is seen ...
