硅酸盐-硫铝酸盐复合水泥水化协同效应研究

摘要

There is a close relationship between the mechanical properties and microstructure of cement hardened, the formation and development of the microstructure of hardened cement is the result of the hydration and hardening process of cement.Therefore, the study on the hydration and hardening process of cement will be of great significance to understand the development of microstructure of cement hydration and hardening microstructure.Based on Portland cement, sulphoaluminate cement and Portland sulphoalminate compound cement (hereinafter referred to as the compound cement) to analyze hydration heat test and scanning electron microscopy (SEM) morphology of cement are analyzed, focusing on the hydration of compound cement, in order to explore the hydration synergy effect of silicate-sulphoaluminate compound cement.%水泥硬化体的力学性质与其微观组构间存在紧密的联系,水泥硬化体微观组构的形成与发展是水泥水化硬化过程的结果.因此,开展对水泥水化硬化过程的研究,将对于了解水泥水化硬化微观组构的发展变化规律及其影响因素有着重要的意义.通过对硅酸盐水泥、硫铝酸盐水泥和硅酸盐-硫铝酸盐复合水泥(以下简称复合水泥)进行水化热测试分析,并且结合扫描电镜(SEM)试验对水泥石的微观形貌进行了分析,重点研究了复合水泥的水化硬化机理,以探究硅酸盐-硫铝酸盐复合水泥的水化协同效应.
