The objective of this study is to simulate the flow behavior of mortar or flowable concrete using the particle method known as the moving particle semi-implicit (MPS) method. The model accounts for flowable mortar or concrete particle dynamics that are based on the Navier-Stokes' equation in Lagrangian form and the conservation of mass. It is validated through a comparison with experimental flow tests. In order to formulate the material constitutive law, mortar or flowable concrete is treated as a highly viscous material in the non-flow state or as a viscoplastic material in the flow state. Yield stress and viscosity are used as the basic rheological properties of the mortar and flowable concrete. Two series of L-box flow tests on mortar and highly flowable concrete are simulated and a good correlation is shown between the simulated and experimental result.
