Mix Design and Physical Properties of Concrete Used in Seongdeok Multi-purpose Dam
성덕 다목적댐 콘크리트의 배합설계 및 역학적 특성
Abstract
Gravity dam use self weight to stand external force like hydraulic pressure. In general, gravity dam concrete is divided into internal and external concrete. Seongdeok dam is gravity dam which is being constructed in Cheongsong-gun, Gyeonsangbuk-do. And upstream cofferdam was constructed to examine the temperature crack due to hydration heat and to decide the height of placement. In this study, we examined the mix design of internal/external concrete and physical properties(compressive strength, adiabatic temperature rise). And we also performed laboratory tests to verify exothermic properties. Lastly, we measured the hydration heat and thermal stress of upstream cofferdam.
중력식 콘크리트 댐은 댐의 자중에 의해 수압 등의 외력에 저항하여 역학적인 안정을 유지하는 댐으로 크게 내부콘크리트와 외부콘크리트로 분류되어 시공된다. 성덕 다목적댐은 경북내륙지역의 안정적 용수공급 및 보현천, 길안천유역의 홍수피해 경감을 위해 경상북도 청송군에 건설 중인 댐으로, 댐길이 274m 댐높이 58.5m 총 저수용량 27.9
