摘要

A robust self compacting concrete (SCC) is characterized by its flowability, passing ability and stability. Numerical simulation of SCC is a valuable tool, which can be used as a means to model and predict concrete workability and to tailor its rheological properties. The simulation of SCC flow could be used for obtaining optimum rheology of the mix to ensure its mobility and segregation resistance during placement. This paper presents the results of numerical simulation of SCC flow using a 2-D computational fluid dynamics (CFD) framework. The commercial CFD software ANSYS/FLUENT was used to perform 2-D simulation of slump flow and L-box tests. The Herschel-Bulkley viscosity model is used for modeling the behavior of fresh concrete. SCC mixes with silica fume as mineral additives was simulated. A good correlation between the numerical simulation and the experimental results is obtained.
