| 摘 要： | 环境气候条件对钢筋混凝土构件的耐久性有很大影响。我国幅员辽阔,各地的气候条件差异显著,造成构件的耐久性寿命也存在较大差异。收集了各主要城市的年平均温度和相对湿度数据,对大气条件下,由碳化引起的,各城市间钢筋开始锈蚀和保护层锈胀开裂的耐久寿命差异进行了比较分析。

| Abstract: | RC beams'durability is significantly affected by environmental climate conditions.Climate diversity exists due to vast cover in territory,which results in differences on the durability life of RC members.We collected the yearly average temperature and relative humidity of main cities.According to the date,research is carried out on difference of the time of beginning of rusting and concrete cover cracking caused by concrete carbonization in atmospheric environment. |
