Abstract：Using rubberized concrete(RC)and normal concrete(NC)as control groups,quasi-static compression tests,static flexural tests,and dynamic impact tests were conducted on polyurea particle concrete(PC)to investigate the effects of polyurea particle content and particle size on the static and dynamic mechanical properties of concrete.The results indicate that the compressive strength of PC is significantly higher than that of RC.The incorporation of polyurea particles significantly enhances the toughness of concrete.When the polyurea particle content is 10%,the peak strain of PC is concentrated between 4‰ and 6‰,at which point PC exhibits better toughness and ductility.When the polyurea particle size ranges from 1.00 to 3.00 mm,PC demonstrates relatively excellent energy dissipation characteristics.
