钢筋混凝土结构结合了钢筋和混凝土的优点,造价较低,在公路桥梁工程中的应用范围非常广泛。在钢筋混凝土结构中,钢筋锈蚀是混凝土工程耐久性的主要病害之一,对桥梁安全使用和寿命带来严重影响,所以防止钢筋锈蚀对提高混凝土耐久性尤为重要。文中详细介绍了钢筋锈蚀的机理及影响因素,并提出了预防措施。 Reinforced concrete structure combines the advantages of steel and concrete, low cost, in the highway bridge engineering is widely used. In the reinforced concrete structure, steel corrosion is one of the major diseases of concrete durability, which has a serious impact on the safe use and life span of the bridge. Therefore, to prevent steel corrosion is particularly important to improve the durability of concrete. The paper introduces the mechanism and influencing factors of steel corrosion in detail, and puts forward the preventive measures.
