  4. Abstract:
  5. In this research, compressive and tensile behaviors of polymer concrete have been investigated. A series of tests were performed on polymer concrete (PC) specimens with different amounts of epoxy resin to investigate the effect of epoxy resin content on behavior of PC. For prediction of this behavior the disturbed state concept (DSC) has been used. The proposed model was then verified by predicting laboratory compressive tests used to find parameters along with independent data sets from other researchers. Moreover, the applicability of existing cement concrete models for predicting the behavior of PC was assessed since they are basically phenomenological, based on experimental observation of the cement concrete testing. Finally, the DSC was compared with other existing models and it was concluded that it has highest accuracy among others
