摘　　要：聚羧酸系高性能减水剂已在上海市预拌混凝土中开始大量应用,但在应用时还存在一些问题,本文介绍了在实际施工中解决混凝土保坍性的方法,在中、低标号混凝土中大量使用的方式,表明聚羧酸系高性能减水剂可在预拌混凝土中普遍使用,具有非常广阔的应用前景。Polycarboxylic high performance water--reducing agent mixed in the premixed concrete in Shanghai is already applied massively, but when application also has some problems,This article introduced solves the concrete guarantees collapses of the nature the method in the actual construction, in marking concrete, in light grade concrete massive use way, Indicated polycarboxylic high performance water--reducing agent may mix in the concrete to use generally in advance, has the extremely broad application prospect.
