摘　　要：从工程适用性出发,介绍了水泥基材料用增稠剂的发展历程、类型及其特点等,探讨了增稠剂对水泥基材料抗离析性能改善机制,总结了增稠剂对水泥基材料流变性能、含气量、凝结时间的影响规律,指出了掺增稠剂水泥基材料的研究趋势。The history, type and thickening mechanism of cement-based materials were introduced from the practical point of view. The mechanism of improving the anti-segregatio performance of viscosity-enhancing admixtures to cement- based materials was explained.The rheological properties, the air content and the setting time of the cement-based materials were put forward, and the research trend of cement-based materials with viscosity-enhancing admixtures was pointed out.

关 键 词：增稠剂 水泥基材料 流变性 含气量 凝结时间 抗离析性能
