Evaluation and Application of Concrete Using Different Types of Binders for 2nd Construction in IIA

2단계 인천국제공항 건설을 위한 콘크리트 결합재 사용 조건에 따른 적용성 평가

In this Paper, concrete durability, coefficient variation of compressive strength, and hydration heat development characteristics of concrete using different types binder for 2nd Phase Construction in IIA were investigated. The experimental results show that the coefficient variation of compressive strength decreased with the slag cement when compared with the replacement of granulated blast furnace slag powder. And the diffusion coefficient of chloride ion decreased with use of a blended cement when compared with using a only portland cement. Also the type of low heat cement is very suitable to reduce the thermal crack caused by hydration heat development.
