This standard specifies tests for determining the primary resonance frequencies of flexural vibration, longitudinal vibration, and torsional vibration of cylindrical and prismatic concrete specimens, and determining the dynamic elastic modulus, dynamic shear elastic modulus, and dynamic Poisson's ratio from this. stipulates the method of Reference 1. This standard specifies the dynamic elastic modulus, dynamic shear elastic modulus, and dynamic Poisson modulus of concrete specimens placed under environmental conditions that cause changes in concrete, such as weather conditions, freeze-thaw effects, and chemical effects. Used for tests that measure changes in ratio. 2. When tested according to this standard, test values may vary even if the specimens are made from the same concrete, if the moisture content, shape, and dimensions of the specimens differ.
