摘要
本文根据粉煤灰水泥系统的反应过程,以及水化产物的特点,采用盐酸选择性溶解法测算粉煤灰的反应程度和粉煤灰的反应程度随时间的变化关系,拟合水化反应动力学方程。分析影响系统水化反应进程的因素。通过研究获取了粉煤灰水泥体系内粉煤灰与水泥熟料水化进程的动力学方程式,探讨两类反应的动力学参数对体系性能产生的作用机制。提出优化粉煤灰水泥性能的技术思路,即通过调控反应条件,同步推动粉煤灰的火山灰活性反应与水泥熟料的水化反应进程。
This paper investigates the reaction process of the fly ash cement system and the characteristics of the resulting hydration products.The selective dissolution method using hydrochloric acid was employed to determine the degree of fly ash reaction and its temporal variation,thereby fitting the hydration reaction kinetic equation.The factors influencing the hydration reaction process of the system are analyzed.Kinetic equations are derived for the hydration processes of fly ash and cement clinker in the fly ash cement system,and the effects of the kinetic constants of the two reactions on system properties are discussed.Recommendations are provided to enhance the properties of fly ash cement by promoting the pozzolanic reaction of fly ash and the hydration reaction of cement clinker.
