Abstract: The correlation between the σ-ε curve characteristics of twelve solid waste coarse aggregate in the crushing value test and the static elastic modulus of concrete was studied experimentally, and the deformation of coarse aggregate in crushing value test was simulated by discrete element method, as well as the reason of big error in calculating elastic modulus of solid waste coarse aggregate concrete by expressions in main codes at home and abroad was analyzed. The results showed that the calculated values of elastic modulus of ordinary density solid waste coarse aggregate concrete by the codes from Chinese, American and European are 45.5%, 15.8% and 52.5% higher than the measured values, respectively;the solid waste coarse aggregate maintains almost elastic state within the linear region of σ-ε curve;the established solid waste coarse aggregate σ-ε curve exponential model has a high degree of fit, R2＞0.99;by introducing the parameters such as average elastic modulus and water content coefficient of coarse aggregate based on the traditional crushing value test, the semi-empirical expression of elastic modulus of solid waste coarse aggregate concrete was established by regression, and R2 is 0.867. Finally, the general applicability of the semi-empirical expression was tested by the measured values from literature, and the high judgment coefficient (R2=0.895) shows the effectiveness of the expression, which provides a basis for fast and reliable prediction of elastic modulus of solid waste coarse aggregate concrete.
