It is very important to understand the long-term exposed concrete durability in actual environment to conduct appropriate maintenance and long-term performance predict of concrete structure. In this study, the experiment is conducted about compressive strength, carbonation, and chloride ion penetration to research Gunkanjima shore core after long-term service. From the experiment result, it is conformed that shore core in Gunkanjima is general healthy while supersonic waves spread speed and compressive strength of shore core in the surface is slightly small. Moreover it is found that large quality deference exists in respect of carbonation and total chloride ion concentration distribution of core in both of sea side and island inside. |
