高性能混凝土外加剂主导官能团二元、三元复合原理

Binary and Ternary Compounding Principles for Leading Functional Groups for High Performance Concrete Additives

依主导官能团的不同存在形式 ,高性能混凝土外加剂的复合 ,可以分为不同种主导官能团和同种主导官能团复合 ,不论二元或三元复合 ,均可用等边三角形组成表示法表示 ,前者以不同种的主导官能团SO3 H、COOH、“SO3 H—COOH”作三角形的顶点 ,后者以同种主导官能团的不同种非主导官能团作三角形的顶点 ,三角形面上的点表示三元复合 ,三条边上的点表示二元复合。三角形表示法可对复合高性能外加剂作定性定量评估、性能预测分析 ,并可以指导复合设计。

According to different forms of leading functional groups existing,compounding of high performance concrete additives can be divided into compounding of different types of leading functional groups and compounding of same types of leading functional groups.No matter binary or ternary compounding,both can be shown by equilateral triangle make up expression.The former takes different types of leading functional groups SO 3H,COOH,'SO 3H-COOH'as apex of the triangle and the latter takes different types of non leading functional groups of the same types of leading functional groups as apex of the triangle,poinys on the triangle plane indicate ternary compounding whereas points on the 3 sides indicate binary compounding.The triangle expression can make qualitative and quantitative evaluation and performance estimate analysis for compounded high performance additives and guide compounding design.
