    Abstract

    The resonant ultrasound spectroscopy (RUS) experimental technique had been used successfully to measure the modulus of elasticity and Poisson’s ratio of hydrated cement paste. RUS is a modern nondestructive acoustic technique, which can be applied to determine the elastic properties of solids with high precision and great efficiency. By measuring the natural resonance frequencies for a single small parallelepiped cement paste sample with water cement ratio of 0.4, the elastic constants and, subsequently, the modulus (E) and Poisson’s ratio (v) were obtained. The results from RUS measurement, E=21.55 GPa and v=0.225, agree with the numerical modeling values.
