摘　　要：不同搅拌方式对水泥体系的分散造成不同程度的影响,探究常用搅拌方法对水泥产生的影响对于工程应用和试验教学有着至关重要的帮助。研究了3种搅拌方法对水泥净浆和不同配合比砂浆的强度、孔隙率和水化产物的影响,对比不同的搅拌结果进行分析和讨论。结果表明:相同时间下搅拌方式的不同导致强度产生变化;多轴搅拌有利于体系微观的分散均匀,改善孔的结构和密实程度;孔隙率的改变会导致试件内部自由水含量和水化产程度产生变化。Different mixing methods have different degrees of influence on the dispersion of cement system.It is of vital help to explore the influence of common mixing methods on cement for engineering application and experimental teaching.It studied the influence of three mixing methods on the strength,porosity and hydration products of cement slurry and mortar with different proportions.The results showed that the intensity changes with different mixing methods at the same time.Multi-axis agitation was beneficial to the uniformity of microcosmic dispersion and the improvement of pore structure and compactness.The change of porosity will lead to the change of free water content and hydration degree in the specimen.
