摘要：
In this paper, the method of dynamic modulus measurement was discussed, which is a method of nondestructive evaluation. This method enables a measurement of progressive changes in the stiffness of the concrete without damaging the specimen and provides reliable values of dynamic modulus. This paper reports the result of the dynamic modulus of elasticity at early age. The comparison of the dynamic parameter between different w/b concrete has been conducted.
