在我国建筑工程混凝土结构中,占据较大比例的则是钢筋混凝土结构。然而钢筋混凝土耐久性造成影响的问题逐渐形成。导致钢筋混凝土结构耐久性丧失的最为主要的原因则是由于钢筋镑蚀造成的。而钢筋保护层的混凝土出现碳化是造成钢筋锈蚀的关键。近年来,在建筑工程中该问题仍未有较为明显的改进。其原因主要是由于其涉及的学科相对广泛,有较大难度存在。本文主要从建筑工程中混凝土出现碳化及冻融的影响因素及处理措施着手进行详细的论述。
In China’s construction of concrete structures, occupy a large proportion of the reinforced concrete structure. However, the problems caused by the durability of reinforced concrete gradually formed. The most important cause of the loss of durability of reinforced concrete structures is due to the pounding of steel. The carbonization of reinforced concrete protective layer appears to be the key to corrosion of steel. In recent years, there is still no obvious improvement in the construction project. The reason is mainly due to its relatively wide range of disciplines, there are more difficult to exist. In this paper, concrete construction of concrete carbonization and freeze-thaw impact factors and treatment measures proceed with a detailed discussion.
