In this study, 25 bridges which material-age was from 10 years to 30 years in Chonnam province were examined for neutralization test in order to obtain durability by examining neutralization. The mechanism of carbonation and influencing factors to the carbonation by considering the depth and the speed of carbonation are compared with data measured from field tests.
Based on the analysis and comparison, the range of carbonation speed coefficient is proposed and the relationship between carbonation depth and remaining lifetime is predicted.
This study aims to provide the reference data, which will calculate lifetime of Reinforced concrete bridge and utilization of carbonation factors.
