Abstract The rheology of cement paste under vibration follows the transformation from Bingham model to Hershel-Bulkly model to Power-Law model. Most of the existing research is obtained through a large number of experiments in the data fitting process, and cannot express the time-varying characteristics of viscosity. Furthermore, thixotropy of cement paste is based on static experiment and cannot be applied under vibration. In this paper a shear-vibration equivalent theory is proposed, which consider the effect of vibration is the same as the shear effect on the viscosity change of cement paste. Combining vibrational shear equivalent theory and HI theory, the rheological changes of cement paste under vibration are obtained through numerical simulation. This theory has been verified by a series of experiments with numerical simulations, and can be used to study the rheology of concrete under vibration.

振动作用下水泥浆体触变性的扩展：剪切-振动等效理论

摘要 振动作用下水泥浆体的流变学遵循Bingham 模型到Hershel-Bulkly 模型再到Power-Law 模型的转变。现有的研究大多是在数据拟合过程中通过大量实验获得的，不能表达粘度随时间变化的特性。此外，水泥浆的触变性是基于静态实验的，不能在振动下应用。本文提出了一种剪切-振动等效理论，该理论考虑了振动对水泥浆粘度变化的影响与剪切作用相同。结合振动剪切等效理论和HI理论，通过数值模拟得到振动作用下水泥浆体的流变变化。该理论已通过一系列数值模拟实验得到验证，
