In this paper, emission and storage amount are evaluated for real RC (Reinforced Concrete) underground structure considering amount including material manufacturing, moving, and construction, repairing timing stage regarding extended service life. Four mix proportions with mineral admixtures are prepared and diffusion coefficient are obtained based on a micro modeling. Referred to carbonation durability limit state, emission and storage amount are evaluated, which shows higher initial emission is caused due to larger unit content of cement and the storage increases with more rapid carbonation velocity. Furthermore various concentration is adopted for simulation of evaluation including measured concentration (600ppm). With higher concentration of outside, carbonation velocity increases. In order to reduce emission through entire service life, reducing initial emission through mineral admixture like fly ash is more effective than increasing storage through OPC since is significantly emitted under manufacturing OPC and storage in cover concrete of RC structure is not effective considering initial concrete amount in construction.
