摘要对一系列水泥浆液的流变特性进行了测量。当在同心圆筒粘度计中测试灌浆时，高剪切混合导致可逆和可再现的流动曲线。根据这些流动曲线计算了宾汉常数。定量研究了水灰比、增塑剂、温度以及与淡水和海水混合对普通波特兰、油井B和高铝水泥浆液流变性能的影响。从这些属性的泵送压力的预测进行了讨论。
Synopsis The rheological properties of a range of cement grouts have been measured. High shear mixing has resulted in reversible and reproducible flow curves when the grout is tested in a concentric cylinder viscometer. Bingham constants have been calculated from these flow curves. The effects of water/cement ratio, plasticizers, temperature and mixing with fresh and seawater on the rheological properties of ordinary Portland, oilwell B and high alumina cement grouts have been quantified. The prediction of pumping pressures from these properties is discussed.
