Microconcrete is normally used to construct the models for shaking table test. The mechanical performance of microconcrete is important for design of dynamic similitude relationship. Dynamic compressive strength test on prismy microconcrete specimens is carried out on static and dynamic testing machine named MTS. The relationship between constitutive relation, compressive strength, modulus, peak strain and failure type of microconcrete under compression and strain rate is studied. The constitutive relation and failure type of microconcrete under different strain rate is similar. The strain at peak value of stress is invariable under different strain rate. The microconcrete is depending on the strain rate. The compressive strength and modulus increase with the increase of the strain rate. The quantitative formulas are presented in this paper, which can be used in design of similitude relationship in shaking table test.
