摘　　要：以目前实践工程中广泛应用的宾汉姆水泥浆液(水灰比为0.75-1.25的水泥浆液)为研究对象,分析了宾汉姆水泥浆液静切力、塑性粘度与析水率等流变参数与水灰比间的定量变化关系。研究结果表明:采用水灰比与宾汉姆水泥浆液静切力、塑性粘度与析水率间的定量变化关系分别计算得到的静切力、塑性粘度与析水率的预测值与对应的实测值间的差异约在20%的范围内变动。因此,本文探讨的水灰比与宾汉姆水泥浆液静切力、塑性粘度与析水率间的定量变化关系可用来预测计算不同水灰比宾汉姆水泥浆液的静切力、塑性粘度与析水率等流变参数。Taking Bingham cement slurry(cement slurry with water cement ratio of 0.75-1.25),which is widely used in practical engineering,as the research object,this paper analyzes the quantitative relationship between the rheological parameters of Bingham cement slurry,such as static shear force,plastic viscosity and water evolution rate,and the water cement ratio.The results show that the difference between the predicted values of static shear force,plastic viscosity and water evolution rate and the corresponding measured values is about 20%.Therefore,the quantitative relationship between water cement ratio and Bingham cement slurry static shear,plastic viscosity and water evolution rate discussed in this paper can be used to predict and calculate the rheological parameters of Bingham cement slurry with different water cement ratio,such as static shear,plastic viscosity and water evolution rate.
