The concrete structure's problems are known to all. The Assessment on the remaining life of the concrete structure can be used to a timely manner for maintenance,which could reduce the costs of building maintenance and reveal potentially dangerous. The carbonized concrete's remaining life was revised,which was based on the research of limit state of concrete's durability.%混凝土结构存在使用寿命的问题.对结构进行剩余使用年限的评定可及时对结构进行维护,减少维护的费用,揭示潜在的危险.在混凝土碳化的耐久性极限状态的研究基础上,对混凝土构件经过一定碳化损伤后,对剩余使用年限进行研究.
