摘要 在水泥水化过程中,主要由化学反应速率或扩散速率控制其水化程度,利用这两个主要过程的特征参数演化关系,本文给出了基于微观球模型的水化动力学方程。该动力学方程对水泥水化反应的基本过程进行了表征,观察各过程的相互关系,可对水泥基材料的水化机理进行解释。水化初期,化学反应速率对水化反应起主导作用;随着水化程度提高,水化反应转由扩散速率控制。 The hydration degree is mainly controlled by chemical reaction or diffusion rate in hydrate process of cement.According to evolution of characteristic parameters in two main processes,the hydrated kinetic equations are given in the paper.The kinetic equations can simulate the main hydrated processes,and an understanding on the hydration mechanism of cement can be emphasized.Chemical reaction dominates in the early stage of hydration,however diffusion rate becomes the dominating factor gradually as the hydration degree increases.
