摘要
先进微观测试手段是国内混凝土减水剂研究的薄弱环节。本文综述了减水剂在固体颗粒表面吸附量、吸附层厚度、吸附性质以及ζ电位等重要参数的常见测试方法,并分析了各种方法的优缺点。
Advanced micro-measurement methods are usually lacked in the research of concrete superplasticizer.In this paper,measurement methods usually used in the research of concrete superplasticizer were reviewed,which included absorption amount of superplasticizers on the surface of cement particles,tickness of absorption layer,absorption type as well as ζ-potential.In addition,advantage and disadvantage of every method were analyzed.
