减水剂在水泥颗粒表面的吸附特性研究进展

Review on the Adsorption Characteristics of Superplasticizers on the Surface of Cement Particles

综述了减水剂在水泥颗粒表面的吸附特性以及减水剂吸附对水泥浆体固液界面性质和水泥水化的影响,分析了影响减水剂吸附效果的主要因素(水泥矿物组成、可溶性碱式硫酸盐、减水剂掺法和减水剂分子结构),介绍了减水剂吸附量的常用微观测试手段,并讨论了减水剂研究中存在的问题.

Adsorption characteristics of superplasticizers on the surface of cement particles and its effects on the properties of solid-liquid interface and cement hydration are reviewed. The main factors influencing adsorption of superplasticizers such as mineral composition of cement, soluble alkali sulphate salt, addition method and molecular structure are analyzed. Micro-measurement methods usually used in the research of concrete superplasticizers are introduced. Furthermore, the shortages in the research work of superplasticizers are discussed.
