目前混凝土中砂子含泥量的波动直接影响混凝土的坍落度大小和保留值。本文合成了三种聚羧酸系高性能减水剂母液,通过三者的复合解决了砂含泥量过高造成的工作性下降的问题,对聚羧酸系高性能减水剂在混凝土搅拌站的推广应用具有重要意义。 At present, the fluctuation of clay content in concrete directly affects the slump size and retention of concrete. In this paper, the synthesis of three polycarboxylate superplasticizer mother liquor, through the combination of the three to solve the problem of decreased workability caused by too high mud content of the polycarboxylate superplasticizer in concrete mixing The promotion and application of stations is of great significance.
