| Abstract: | The durability of concrete in ocean environment is studied.Reasons and mechanism which cause rusty of reinforced bars are also presented.Test data are introduced to explain the effect of SO 2- 4?Cl - in seawater on concrete and bars.In the meantime,reasons which affect durability of concrete are considered to be results of several factors working together.Measures to improve the durabiltiy of concrete structures in ocean environment are presented. |
