浅谈钢筋混凝土耐久性的影响因素及对策

混凝土结构是应用非常广泛的一种结构形式，但是由于其结构自身和使用环境的特点，使得混凝土存在严重的耐久性问题。通过对国内外钢筋混凝土工程耐久性现状的介绍，从混凝土的碳化、冻融破坏、侵蚀性介质的腐蚀、混凝土碱集料反应、钢筋锈蚀等方面论述了影响混凝土结构耐久性的因素及其对混凝土的破坏机理，并针对性地提出了预防的措施。

Talking about the Factors Influencing the Durability of the Reinforced Concrete and Countermeasures

The concrete structure, which is a widely used structural form, has serious durability problem because of the features of the structure of itself and the working environment. Through the introduction to the present situation of the durability of foreign and domestic reinforced concrete engineering, this paper discusses on the factors influencing the durability of the reinforced concrete structure and the failure mechanism of the reinforced concrete structure from aspects of the carbonization of concrete, the freeze-thaw failure of concrete, the corrosion of corrosive mediums, alkali-aggregate reaction of concrete, and corrosion of reinforced bar, etc., and puts forward some corresponding measures.
