- Abstract:
- To reveal the influence of crack on durability of reinforced concrete structure under chloride environment, authors analyzed the change rules about durability of concrete with load cracks, nonload cracks and artificial cracks by combining the existed references. The effects of crack type (artificial or natural crack), width, depth and distance on concrete durability which contains penetrability, chloride ingression and steel corrosion were pointed out. The models about chloride ion transportation in cracked concrete under saturated and unsaturated state were also introduced. The basic conclusions and key points needed in further study were finally put forward. The obtained results can be served as references for the future research on durability of cracked concretes under chloride environment.
