Experimental study of complete grading concrete in dynamic states is very important for aseismic safety design of the high arch dam. The current situation of dynamic characteristics experiment on complete grading concrete is reviewed. And the change law of dynamic strength of complete grading concrete under different loading conditions is out- lined. Then the test equipments and measurement method are summarized. Finally, 15 MN large scale dynamic material test system is introduced particularly and the development trend of dynamic characteristics experiment on complete grading concrete is discussed.
