플라이 애시와 고로슬래그 미분말의 복합사용한 콘크리트의 내구성능 향상 효과

Combined Effect of Fly Ash and Granulated Blast Furnace Slag on Durability Performance

Ternary blended concrete containing both fly ash and granulated blast furnace slag is initial cost effective, and environment friendly. Furthermore, it has many technical advantages such as improvement of long term compressive strength, rheology property, reduction of hydration heat, etc. However, use and data on the performance of ternary blended concrete are limited, and it is necessary to study on the adoption of this technology. This study examined the durability performance of ternary blended concrete comparing with binary blended concrete and ordinary portland concrete. From the results of this study, it was concluded that ternary blended concrete is very suitable to submerged zone under maine environment.
