聚羧酸高性能减水剂是一种新型的高效的减水剂,亦是目前国内外研究的热点。本文结合国内外资料综述了聚羧酸高性能减水剂的组成,讨论了反应单体、聚氧烷基链和聚合物相对分子质量及其分布、减水剂掺量等影响减水剂性能的因素。 Polycarboxylate superplasticizer is a new type of highly efficient water reducer, it is also a hot spot at home and abroad. In this paper, the composition of the polycarboxylate superplasticizer is reviewed based on the domestic and foreign data. The relative molecular weight and distribution of the reactive monomer, polyoxyalkylene chain and polymer are discussed. The properties of the superplasticizer, such as the amount of the superplasticizer, the elements of.
