Analysis of carbonation service life prediction model of reinforced concrete structures

Carbonation of concrete is one of the important factors that affects the durability of concrete structures.According to the rule of carbonation life,the existing carbonation life prediction model of concrete structures were analyzed and compared,and were verified with experimental data or practical examples.In addition,the influencing factors of the models were analyzed and compared with eath other.It is suggested that some important factors should be emphasized on the control during the design,construction and maintenance of concrete structures.
