混凝土的抗碳化性能及对钢筋的保护作用在混凝土耐久性研究中占有重要位置,因此,目前致力于混凝土碳化及钢锈试验的人日益增多。多年来,我国混凝土碳化及钢筋锈蚀方面一直没有统一的试验方法,各单位各行其是,给实际应用带来诸多不便,试验结果缺乏可比性。近三年来,我所通过大量的试验与研究,摸索了 The carbonation resistance of concrete and its protective effect on reinforcing steel occupies an important position in the study of the durability of concrete. Therefore, there are increasing numbers of people who are currently working on concrete carbonization and steel rust testing. For many years, there has been no unified test method for concrete carbonization and corrosion of steel bars in China. Each unit has its own way, which brings a lot of inconvenience to practical application and lacks comparability of test results. In the past three years, we have explored a large number of experiments and studies.
