混凝土腐蚀对其耐久性产生不利的影响，并导致了大量工程破坏的实例。多年来，混凝土发生腐蚀的条件一直是人们感兴趣的一个问题。本文应用热力学方法计算了混凝土在不同的环境中腐蚀产生的条件，提出了混凝土腐蚀取决于外部环境介质与溶液酸碱性两个因素的结论，这两个因素相互依存，任何强调某一个因素作用的做法都是片面的。 Concrete corrosion has an adverse effect on its durability, and has led to a large number of engineering failures. For years, the condition of concrete corrosion has been a problem that people are interested in. In this paper, thermodynamics method was used to calculate the conditions of concrete corrosion in different environments. It was concluded that the corrosion of concrete depends on two factors: the external environment medium and the solution acidity and alkalinity. These two factors are interdependent, any one stressing the role of a certain factor. The practices are one-sided.
