Bingham's model is generally used as a rheological model for fresh concrete. However, Bingham's model for homogeneous materials is not always adequate to express the behavior of composite material such as fresh concrete. In this study, the numerical analysis of the flow of fresh mortar is carried out by visco-plastic finite element method (VFEM) using the shear strain dependent viscoplastic model. It is shown that the analytical results are in good agreement with the experimental ones, and that this model is appropriate. Furthermore, the mechanism of blockage of fresh mortar is discussed analytically.
