摘　　要：结合南京市纬三路过江通道工程,在C40混凝土原始配合比基础上进行对比试验,研究不同掺量脂肪族减水剂对混凝土坍落度、坍落度经时损失以及抗压强度的影响,以充分发挥脂肪族高效减水剂的改性作用。According to the tunnel crossing river of Weft Three Road in Nanjing, based on mix proportion of C40 concrete, this paper which employs contrast test, shows that different percent of aliphatic admixture produce different effect on concrete slump, slump constant loss and com- pressive strength. In order to develop the ability of aliphatic efficient admixture as completely as possible.

关 键 词：脂肪族减水剂 坍落度 混凝土强度 最优掺量
