随着时代发展,海洋开发工程越来越多,对钢筋混凝土结构的使用寿命要求越来越高,因此海洋工程的钢筋混凝土耐久性能得到广泛关注。考虑到海洋工程钢筋混凝土服役环境,本试验采用干湿循环方法加速混凝土碳化,研究碳化作用对氯离子在混凝土内部传输的影响,结果表明:混凝土碳化和氯离子传输是相互影响的,在一定程度范围内,混凝土碳化越严重,氯离子传输就越困难,对进一步研究海洋工程利用碳化作用来防止钢筋锈蚀起到指导性的作用。
With the development of the times, there are more and more marine development projects and more and more requirements on the service life of the reinforced concrete structures. Therefore, the durability of the marine engineering reinforced concrete has drawn extensive attention. Considering the service environment of offshore reinforced concrete, the experiment uses the wet-dry cycle method to speed up the carbonation of concrete, and studies the effect of carbonation on the internal transport of chloride ions in concrete. The results show that concrete carbonation and chloride ion transport influence each other to a certain extent Within the scope of the concrete carbonation is more serious, the more difficult the chloride ion transmission, the further study of the use of carbonation of marine engineering to prevent steel corrosion play an instructive role.
