The Discrete Element Method(DEM) has become a powerful numerical method for analysing discontinuous media. This paper provides a new ellipse particle modeling of fresh concrete by DEM. So far, research has been limited to experimental research and qualitative simulation. In this research, the parameters are defined from rheology. Then, a quantitative simulation is proposed. Slumping behaviors of fresh concrete are simulated.
