An ultrasonic method for estimation of elastic properties of R-bone cement after immersion in Ringers solution

The aim of this investigation is to establish an improved non-destructive ultrasonic through-transmission technique to monitor the setting behaviour of calcium phosphate cement samples. On the basis of ultrasound techniques the elastic properties of cement paste after different soaking time in Ringer's solution were measured. Young's modulus, the rigidity modulus, and Poisson's ratio were calculated from measurements of density and ultrasonic longitudinal and shear wave velocities.
