摘要
作为一种新型高性能减水剂,聚羧酸减水剂目前已成为国内外研究与发展的热点。概述了高效减水剂的研究与发展现状,从聚羧酸类高效减水剂的分子结构、性能特点、合成方法、作用机理及目前在国内大型工程中的应用现状做了讨论,提出了聚羧酸类高效减水剂今后的研究发展趋势。
As a new high-performance superplasticizers, the research and development of polycarboxylate superplasticizers have become a hot at home and abroad. Superplasticizers＇state of the art being outlined, The chemical structure, perfor-mances, synthesis methods, acting mechanisms and some engineering applications in our country of polycarboxylate super-plasticizer were specially discussed in this paper. The future research and development trends of polycarboxylate superplasticizers were proposed.
