| Abstract: | Concrete corrosion is the main failure mode to wharf.There are four main factors influencing the durability of wharf,including freeze-thaw cycles,sulfate attack,reinforcing steel bar corrosion and alkali-aggregate reaction and the failure mechanism and situation of the four effect factors are explained respectively.The way to improve the durability is proposed and the suggestion on considering the failure situation of practical engineering is proposed also. |
