摘要：通过测试流动度和由Bingham流变模型拟合所得的流变参数，研究了未掺与掺聚羧酸减水剂（TX50）两种条件下含泥量对水泥浆体流变性能的影响因素及其规律。结果表明：含泥量对水泥浆体塑性黏度的影响程度明显大于其对流动度的影响；水灰比与未掺减水剂的水泥浆体的流动度、塑性黏度、屈服应力分别呈线性关系、幂函数关系、指数关系；减水剂与RP8抑制组分的掺入均可增加水泥浆体的流动度，降低塑性黏度，且对流动度的影响程度明显大于对塑性黏度的影响程度。 Abstract: By testing the fluidity and the rheological parameters fitted by the Bingham rheological model, the influence factors and laws of clay content on the rheological properties of cement paste under the two conditions of not admixed and admixed with polycarboxylic acid water reducer(TX50) were studied. The results show that the effect of clay content on the plastic viscosity of cement paste is significantly greater than its impact on fluidity. The water-cement ratio and the fluidity, plastic viscosity, and yield stress of the cement paste without water reducer are linear, power function, and exponential respectively. The mixing of water reducer and RP8 inhibiting component can increase the fluidity of cement paste and reduce the plastic viscosity, and the impact on fluidity is significantly greater than the impact on plastic viscosity.
