The elastic constants of wet and dry concrete specimens of known composition have been calculated from those of cement paste, water and two types of aggregate by using a theoretical model due to Boucher. The densities were also calculated and the velocities of three types of ultrasonic wave were obtained. It has been shown that the calculated velocities are in satisfactory agreement with those measured on some typical concretes. The suitability of gamma radiometry as a measure of density was also assessed by the measurement of mass absorption coefficients on all the materials involved using a cs source of energy 667 kev.(a) /TRRL/
