摘要
本文综述了 2 1世纪高性能减水剂的特征及其与高性能混凝土发展相互促进的关系 ,从高效减水剂分子的功能化结构设计角度着重分析了磺酸系减水剂分子结构改性和聚羧酸系减水剂梳型分子结构设计方法 ,进一步提出减水剂高性能化的三种途径 :物理复合、化学改性、新型分子设计。
? This paper sums up the characters of high performance water reducers in the 21st century and the relations of mutual promotion with high performance concrete, in view of the functional design of molecule structure, the modified way of sulphonate based superplasticizers and the design for the comb type structure of polycarboxylate based superplasticizers are specially analysed, and three high behavior pathways for them, such as physical compound, chemistry modification and new type molecule structure design etc., are furtherly put forward. 〔
