摘　　要：本文简述了改性氨基磺酸盐系高效减水剂的合成，并把改性氨基与传统的萘系减水剂进行热复合，研制成高性能外加剂，然后检测了流动度、坍落度、强度、含气量、电通量、抗渗性等应用项目，实验表明该外加剂减水分散力高，坍落度损失小，能够满足地铁轨道混凝土的耐久性要求。This paper sketches the composition of modified sulfamate type high efficiency water reducing agent, conduct thermal compounding with modified amino and traditional naphthalene series water reducing agent and high performance admixture was developed, then detects application projects as fluidity, slump, strength, gas content, electric Flux, impermeability, etc. The experiment shows that the admixture has high water reducing dispersion force and low loss, which can meet the requirement of the durability of subway rail concrete.

关 键 词：高性能外加剂 坍落度损失 热复合 耐久性
