[Purposes] In this paper, the impact of vibratory agitation on the properties of ultra-high-performance concrete materials is compared and analyzed by simulation and experimental methods. [Methods] First of all，the three-dimensional model of the double-horizontal shaft vibratory mixer is established. Then, the EDEM simulation software is introduced for simulation analysis. Under the premise of ensuring that the model can make the material fully mixed, a set of non-vibration stirring and vibration stirring are designed to comparation and study. With the post-processing function of EDEM, the material movement trajectory and matrial uniformity at the end of the mixting are analyzed with time. Finally, physical properties of the blended material are tested through field tests. [Findings] Based on the same speed, simulation results show that the blended material dispersion coefficient of vibratory stirring is 0.186 and the non-vibration stirring is 0.247 at the end of production, and the uniformity of the mixture is improved by 25%. Comparing with the non-vibratory stirring，the engineering test results of the premix and the non-premix show that the expansion degree is increased by 7.4%-16.2%, the collapse degree is increased by 3-5 mm, and the uniformity is increased by 21%. [Conclusions] Overall, the vibration stirring effect is better for ultra-high performance concrete preparation.
