作者试图在传统波特兰水泥石结构研究的基础上,建立一个组成和结构可调整和可控制的胶凝材料研究体系——CSH体系,旨在实现材料在分子水平上的组成结构设计。本文是该体系初期研究工作的一部分,以多种测试方法研究了CSH相在水热合成、脱水煅烧和脱水相再水化过程中硅酸阴离子聚合状态的变化规律及其主要影响因素和脱水相水化硬化体的分子结构、孔结构对其力学性能的影响;本文讨论了上述三个阶段的反应机制;探讨了硬化体的结构形成过程;提出了凝胶态胶凝材料的新概念并对晶态、玻璃态、凝胶态胶凝材料的特性进行了比较。
Based on the study of traditional Portland cement stone structure, the authors set up a CSH system that is a composition and structure-adjustable and controllable cementitious material research system, aiming to achieve the compositional structure design of the material on the molecular level. This article is part of the initial research work of the system. The changes of the anionic polymerization state of silicic acid in hydrothermal synthesis, dehydration calcination and rehydration of the dehydration phase and its main influencing factors and dehydration phases were studied by various test methods. The influence of the molecular structure and pore structure of the hydration hardened body on its mechanical properties; this article discusses the reaction mechanism of the above three stages; discusses the structure formation process of the hardened body; proposes a new concept of the gelled state gelling material and The properties of the crystalline, glassy, and gelled gelling materials were compared.
