摘　　要：减缩剂在水泥基材料中的研究和应用处于初级阶段,其主要作用是为了降低水泥基材料收缩.此外,减缩剂对水泥基材料其他性能也会产生较大影响.从水化性能、工作性、力学性能和耐久性4个方面重点论述了减缩剂对水泥基材料性能的影响,并进行了机理分析与总结.最后对掺减缩剂水泥基材料的进一步研究工作提出了相应的建议。Although shrinkage-reducing admixture(SRA)applied in cement-based materials is still in its infancy,its main role is to reduce the shrinkage of cement-based materials.In addition,SRA has a great impact on other properties of cement-based materials.The effect of SRA on the hydration,workability,mechanical properties and durability of cement-based materials is mainly reviewed.And the mechanism is also discussed.The existing problems in the study are analyzed,and the corresponding development trend of cement-based materials with SRA is pointed out.
