| 要旨 | Fresh concrete is a typical thixotropic material with a time-dependent rheological characteristic. In this study, a general Discrete Element Method (DEM) model for fresh concrete was firstly established and the material parameters were calibrated by the rheological test. Then, a thixotropy DEM model of fresh concrete was proposed by introducing a time-dependent particle contact model into the general DEM model. The changes of fresh concrete's lateral pressure on the wall and yield stress with elapsed time were successfully addressed with this thixotropy DEM model. |
