Paper Title:
Survey and Evaluation of Concrete Durability for 40 Sluices in Coastal Area, East China
  Abstract

Total 40 sluices which are all front-line facing the seas have been surveyed, for the hydraulic concrete durability research in the coastal area. The corrosion and damage of concrete, including cracking, carbonization, chloride-induced corrosion and abrasion have all be counted and analysed. It has been found that the inadequacy of concrete cover ply is quite common and leading to severe reduction for structural durability. The carbonation depth of concrete in coastal area, especially impacted by wind and rain directly, is apparently larger than others. The correlativity between carbonation depth and age of concrete has also been analysed, involved the influence of concrete compressive strength. The chemical attack and biological erosion, according to the survey result, led to relatively light damage to the sluice concrete. In the end of this paper, a fuzzy comprehensive evaluation(FCE) method has been adopted, for the quality evaluation of sluices concrete structure.
