摘要
聚羧酸盐系高性能减水剂是当今混凝土外加剂研究中较为前沿的课题之一,该类减水剂具有低掺量、高减水率、抑制坍落度经时损失等特点。阐述了聚羧酸盐系高效减水剂的国内外研究现状、结构性能、合成方法、对混凝土的作用机理及其在工程中的应用,并对其研究进行了评述。
The polycarboxylate-type high performance superplasticizer is one of the most advanced research project of the concrete admixtures nowadays.It features for lower additive,higher fluidity effect, and preventing concrete mix from slump-loss with time duration.The recent research condition both at home and abroad, the performance, the method of synthesis, the working mechanisms on concrete and the use in the engineering were summarized.The development trends of the polycarboxylate-type high performance superplasticizer were prospected.
