Abstract In the case of coupled solids-solution reactions, any mean accelerating or decelerating one of the reaction, will also change the other reaction(s) in the same way, through the coupling mediated by the solution. The observation of any kinetic change by one of these means should not lead to too rapid conclusion on the limitation of kinetics and it must be done with great caution. Contrary to what Gartner mentioned, the acceleration of C 3 S hydration by the addition of calcium silicate hydrate seeds, is not a trivial evidence suggesting that hydration kinetics “has to be” limited by the C-S-H precipitation and that the C 3 S dissolution can be neglected. In our paper, efforts have been made to highlight again the importance of C 3 S dissolution, based on the Gartner's discussion points.

C 3 S水合的限速反应——对E. Gartner“硅酸三钙水合动力学的新观点”讨论的回复

摘要 在固-溶液耦合反应的情况下,任何加速或减速反应的手段,也会通过溶液介导的耦合以相同的方式改变其他反应。通过这些方法之一观察任何动力学变化不应导致对动力学限制的过快结论,并且必须非常谨慎地进行。与 Gartner 提到的相反,通过添加硅酸钙水合物种子加速 C 3 S 水合并不是一个简单的证据,表明水合动力学“必须”受到 CSH 沉淀的限制,并且 C 3 S 溶解可以被忽视了。在我们的论文中,根据 Gartner 的讨论要点,已努力再次强调 C 3 S 溶解的重要性。
