| Abstract: | According to foe circumstances of port reinforced concrete structures lying in wavesplashed area suffered from serious damage due to reinforcement rust after only 8 -10years operation, a few necessary technical countermeasures, such as water cement ratio ofthe concrete should not be greater than 0. 40, protective cover of reinforcement should begreater than or equal to 65 mm, and NSF admixture should be used in the concrete, areherein recommended in order to ensure 50 years over service life of the port structures insouth China. |
