官能团

Based on the judgement on the existing of whether leading functional group or unleading functional group,if unleading exists,what about its bond type,with these pre-classification information,a new classification methods and uint structure model which can reflect the name,composition,stucture and function was put forward in this paper.

前言 高性能混凝土外加剂分子只存在磺酸、羧酸两种主导官能团，以磺酸、羧酸、&磺酸-羧酸&三种方式存在，因而把高性能外加剂分成磺酸、羧酸、&磺酸-羧酸&三大系列 [1、2 ]。磺酸系列外加剂的一个重要性能是高减水率，故有时将它称之为高效减水剂。
