combined effects of chemical actions by containing chlorides and the freeze-thaw action is also a problem which has not yet been fundamentally solved. Furthermore, surface deterioration of concrete was considered as accelerate factor of concrete durability tended to decrease. This study presents the experimental results of frost durability including resistance to freezing-thawing and suface scaling of concrete. Mixing design was proportioned with the various water-binder ratio between 0.37 and 0.47 and three different binder compositions corresponding to Type Ⅰ cement without any supplementary cementitious materials(OPC), Type Ⅱ cement with 50% blast-furnace slag replacement(BFS50), and ternary cement with Type Ⅲ cement, 15% fly sah, and 35% BFS replacement (BFS 35%+FA 15%).
Test results showed that the mixing design with BFS 50% and BFS 35%+FA 15% exhibited higher durability factor than that made with OPC only. Finally, the use of blend cement containing salg can be used effectively in terms of frost durability of the concrete exposed to severe condition like as coastal environment.
