摘要：为满足流动性和强度要求的水泥流态固化土配合比，将内蒙古准格尔出产的黏土与砂混合后添加水泥制备成水泥固化土进行试验。首先在黏土里掺入适量的砂制成75%和50%黏土的原料土，然后通过添加水灰比为3、5和7.5的水泥浆液制备水泥流态固化土，在水灰比一定的情况下，确定了水泥流态固化土的含水率、流动度和单轴抗压强度之间的关系。结果表明:相同配合比的单轴抗压强度主要取决于含水率和原料土总质量；当水灰比相同时，单轴抗压强度随着流动度的减小而增大，流动度随着含水率的增加而增加。研究成果为水泥流态固化土制备提供理论依据与实用配比指导。

Abstract：To meet the requirements of fluidity and strength,the cement slurry stabilized soil mix ratio was prepared by mixing clay from Zhungeer,Inner Mongolia with sand and then tested.Clay was mixed with an appropriate amount of sand to make soil raw materials containing 75% and 50% clay,and then cement slurry was added by controlling the water-cement ratio to prepare cement slurry stabilized soil.Under the condition of a constant water-cement ratio,the relationship between the moisture content,fluidity and uniaxial compressive strength of cement slurry stabilized soil was determined.The results show that the uniaxial compressive strength of the same mix ratio mainly depends on the moisture content and soil mass;When the water-cement ratio is the same,the uniaxial compressive strength increases with the decrease of fluidity,and the fluidity increases with the increase of moisture content.The research results provide a theoretical basis and practical mix ratio guidance for the preparation of cement slurry stabilized soil.
