Abstract：The elastic constants for rubberized concrete were investigated based on the micromechanics theory by means of differentiation method,and the equivalent elastic constants of rubberized concrete with different particle sizes were calculated under the condition of several volume contents. Through the comparison and error analysis between calculated results and experimental data,the dispersion toughening mechanism of rubberized concrete were studied. This paper analyzed the cause of error from three aspects, which were rubber powder content,specimen molding,and microcosmic structure respectively. And the change law of bend to press ratio of concrete is also researched. In conclusion,by comparison the theoretical calculation and experimental results available have a nice consistency,which shows that differential method is a feasible and effective way to predict the elastic constants of rubberized concrete,and the excellent mechanical property index of rubberized concrete could keep stable when the volume fraction is 2.4%.
