摘　　要：现在聚羧酸减水剂得到了越来越广泛的应用，但是其缓释功能会造成混凝土的泌水离析，影响泵送、施工以及拆模后混凝土的外观、强度和耐久性。本文结合实际工程，从商品混凝土、施工和外加剂各个方面对这个问题作了详细的分析，总结了一套行之有效的解决办法。Nowadays, Poly carboxylic acid water reducing agent get more and more extensive application, but its slow release function will cause the bleeding segregation of concrete, influencing pumping, construction and the appearance, strength and durability of after stripping concrete. Combined with practical engineering, this paper make a detailed analysis on this problem from various aspects as commodity concrete, construction and admixture, and summary a set of effective solutions
