Abstract :
The aging of hydraulic concrete construction has been surveyed in the east of Zhejiang. The chloride-induced corrosion on the concrete surface was counted and analyzed. The relationships of 28 days concrete strength, water-cement ratio, admixture, sand ratio and the 28 days electric flux ratio are compared by the Compos System. The influence of the chloride ion diffusion is studied under changing of mix proportion. It has be found that the inadequacy of concrete cover ply is quite common and leading to severe reduction for structural durability.
