Durability evaluations to assess the deterioration of reinforced concrete structures in the present have been considered only individual deterioration factors such as salt damage and carbonation. Also, indoor accelerated experiments have not been able to realize the combined deterioration factors that actually affect real concrete structures.
Therefore, in this study, mixing design was proportioned with the various water-binder ratio 0.55 binder compositions corresponding to Type I cement without any supplementary materials(OPC), Type Ⅱ cement with 50% blast-furnace slag replacement (BFS50), TypeⅢ cement with 15% fly ash replacement (FA15), and ternary cement with TypeⅣ cement, 15% fly ash, and 35% slag replacement (BFS35+FA15).
And this study is carried out to compare individual deterioration test with combined deterioration test and to investigate the effect of the permeation of deterioration factors such as CO₂ and chloride ion under the combined deterioration environments. After setting up various deterioration factors and levels such as carbonation, salt damage, and the repetition of drying-wetting, items such as carbonation depth, chloride ion penetration depth were evaluated under the combined deterioration environments.
The results showed that carbonation depth, chloride ion penetration depth were increased according to the elapsed of ages. Also mixing design with BFS50% and BFS35%+FA15% exhibited higher durability factor than that made with OPC only.
