氯氧镁水泥水化历程的影响因素及水化动力学
Hydration Kinetic and Influencing Parameters in Hydration Process of Magnesium Oxychloride Cement
摘要
Abstract
The hydration mechanism of magnesium oxychloride cement (MOC) was investigated by a mode TAM Air eight-channel isothermal conductive calorimeter in order to predict and improve the performance of MOC. The experiment of hydration heat-release was carried out in different MOC systems, and the parameters effect on the hydration process was analyzed. The kinetic equation of hydration process for MOC was investigated. The results show that the different stages of hydration process are controlled by different parameters. The hydration was controlled by autocatalytic reaction in the acceleration stage and by diffusion in the decay stage, and the hydration was controlled by both chemical reaction and diffusion in the retardation stage. In addition, the hydration process of the system was also affected by the activity of MgO, the reaction temperature and the types and dosage of admixtures as well.关键词
