Abstract

In the present contribution, we deal with the question whether the equilibrium of the silica/water reaction shifts under tensile stresses to an increased or reduced hydroxyl concentration or, equivalently, which sign the reaction volume shows. From our analysis on the basis of the Le Chatelier–Braun Theorem, it can be concluded that the equilibrium constant of the water/silica reaction is enhanced due to tensile stresses and that the reaction volume change is positive.

水/二氧化硅反应的反应体积的符号

摘要

在目前的贡献中，我们处理二氧化硅/水反应的平衡是否在拉伸应力下转变为增加或减少的羟基浓度，或者等价地表明反应体积的问题。从我们基于Le Chatelier-Braun定理的分析中可以得出结论，水/二氧化硅反应的平衡常数由于拉伸应力而增强，并且反应体积变化为正。
