引用本文摘 ? 要：通過測試流動度和由Bingham流變模型擬合所得的流變參數，研究了未摻與摻聚羧酸減水劑（TX50）兩種條件下含泥量對水泥漿體流變性能的影響因素及其規律。結果表明：含泥量對水泥漿體塑性黏度的影響程度明顯大于其對流動度的影響；水灰比與未摻減水劑的水泥漿體的流動度、塑性黏度、屈服應力分別呈線性關系、冪函數關系、指數關系；減水劑與RP8抑制組分的摻入均可增加水泥漿體的流動度，降低塑性黏度，且對流動度的影響程度明顯大于對塑性黏度的影響程度。 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.
