粘土-水泥浆流变性及其影响因素研究

Study of Rheological Properties of Clay-Cement Pastes and Their Effect Factors

摘要: 在详细研究了粘土－水泥浆的流变特性及其影响因素后认为，该浆液是一带屈服值的假塑流体，其流变曲线为不过原点且凹向剪切速率轴的曲线，流变模型符合改进的双曲模型，该浆液既具有剪切稀释作用又具有振凝性，最后探讨了粘土水泥浆的作用机理。

Abstract: The study of clay-cement pastes has revealed that the paste is a pseudo-plastic fluid which has yield value, and that its rheology curve is a curve which does not pass the original point and is concave to the axis of shear strain rate. It is also concluded that the paste has shear thinning effect and rheopexy. The action mechanism of the paste is also discussed primarily.
