| Abstract: |
Pumping is the most commonly used construction method for modern concrete transportation and pouring. This paper summarizes the theoretical and experimental research results on the flow behavior characteristics and pumpability prediction of pumped concrete. The formation mechanism of lubrication layer based on shear induced particle migration theory is introduced, and the distribution of concrete shear rate and flow rate in the pipeline is analysed. This paper discussed three prediction methods of concrete pumpability, including empirical judgment, coil test and pumping resistance calculation. Thus, the cognition of concrete pumping process can be improved and reference for engineering and technical personnel in pumping construction can also be provided. |
