Concrete pumping technology is widely applied in the construction industry, especially in high-rise buildings and large-span bridges. However, during the actual pumping, concrete may bleed or get segregated, leading to the blockage of a pipe. In order to improve the pumping efficiency and reduce the blockage risk, the flow of fresh concrete with a single-size coarse aggregate(CA) in pipe was simulated, and the effects of size and shape, and volume fraction of CA on the pipe blockage were studied using a Computational Fluid Dynamics-Discrete Element Method (CFD-DEM) coupling method. The flow ve...
