Abstract: In this paper, the double-horizontal-shaft vibrating mixer is taken as the research object, and the effect of the vibrating mixing on the performance of UHPC materials are contrasted and analysed in simulations and tests. Firstly, a three-dimensional model of the double-horizontal-shaft vibrating mixer is constructed, and the EDEM software is imported for simulation analysis. Then, on the premise that materials are fully mixed in the model, a set of contrastive studies between the non-vibrating mixing and vibrating mixing was designed. The post-processing function of the EDEM software is used to analyse the material movement after mixing and the rule of the material uniformity changing over time. Finally, various performances of the material are tested in field tests. Overall, for UHPC preparation, the effect of the vibrating mixing is better than that of the non-vibrating mixing.

Keywords: ultra-high performance concrete; UHPC; vibrating mixing; EDEM; simulation analysis; material performance.
