One of the reasons is that most of blended cement is blast furnace slag cement type B. Blast furnace slag cement type B is available in a variety of situations, however it have not been able to use effectively characteristics of ground granulated blast furnace slag. In this research, it will be intended to improve the performance of cement was mixed blast furnace slag with fly ash and limestone powder. And various durability tests and hydration analysis were conducted. As a result, in carbonation, the amount of additional is dominant. On the other hand, in alkali-silica reaction, a small amount of fly ash was affected. However, limestone powder has not affected. Moreover, in penetrating chloride ion, resistance was higher in amount of blast furnace slag. However, increasing the amount of limestone powder mixture has been confirmed to obtain a higher resistance to penetrate chloride ion. As a reason, it is cleared that the amounts of mono carbonate hydrate and monosulfate hydrate can significantly affect.
