本文从水泥化学的观点,把负温环境下使用特殊外加剂时的混凝土寻求水泥浆的冻结温度和使用量的关系,在各种温度条件下养护时水泥石的抗压强度和结合水量的关系,冻融交替时水泥石的冻结温度变化规律和结合水量等的关系。另外水泥石毛细孔径分布的测定和电子显微镜观察,是从水泥石内部组织结构加以综合性探讨。
From the perspective of cement chemistry, this article seeks the relationship between the freezing temperature and the amount of cement used in concrete with a special admixture in a negative temperature environment, and the relationship between the compressive strength of cement stone and the amount of water in curing under various temperature conditions. , Freeze-thaw alternation of cement stone freezing temperature variation rules and the relationship between the amount of water. In addition, the determination of pore diameter distribution of cement stone and electron microscopy observation are comprehensively discussed from the internal structure of cement stone.
