| Abstract: | Based on the concrete degradation situation investigation and analysis for 13 coastal sluices,the causes which leading to concrete degradation have been summarized.The concrete covering layer burst and peels off,which leading to the steel bars pocking and rotting,is the major expression of concrete degradation.The fundamental measure for raising the structure durability is enhancing the concrete material＇s ageing resistance,and the favorable construction quality is also important for ensuring concrete durability. |
