聚羧酸系超塑化剂与水泥单矿的界面作用及对单矿水化的影响OA北大核心CSCDCSTPCD
Interfacial Interaction between Polycarboxylate-based Superplasticizer and Cement Component Minerals and Its Impact on the Hydration Behavior
聚羧酸系超塑化剂(PC)与水泥颗粒间的相互作用是开发新型PC的理论前提,而水泥组成的复杂性使PC与水泥单矿间的作用研究成为热点.本文综述了PC在单矿上的吸附特性及其吸附对单矿zeta电位与水化的影响.PC在单矿上存在不均匀吸附；在铝酸三钙上的插层作用与其分子结构具有内在联系；单矿的zeta电位值与溶液组成息息相关；最后介绍了PC对单矿水化行为及水化产物影响.
Interactions between polycarboxylate-based superplasticizer and cement particles are the basic theory for the development of novel designed PC. The impact of PC onto cement component minerals has attracted much attention due to the complex composition of cement. Adsorption characteristic of PC and its effect on the zeta potential and hydration behavior has been well reviewed in this paper. It is established that not a uniform adsorption onto minerals exists.…查看全部>>
