| Abstract: | Owing to the existing bridges can not meet the needs,using of the old bridge piles foundation arising from bridge conversion has become a common problem.Combined with the Yuanze Bridge piles reconstruction project in Wuhu City,a series of durability test including carbonation depth,chloride ion content,f-CaO and reinforcement corrosion is illustrated.The aim of the test is to provide a basis for engineering design and construction,to avoid repetitive construction,to save construction cost,also to form the s... |
| Keywords: | using of old piles carbonation depth chloride ion content f-CaO reinforcement corrosion |
