Provided is a high-specific gravity concrete composition for an offshore concrete structure, which is required for manufacturing, installing, and reinforcing an offshore concrete structure, which can be used to prepare for a rapid climate change and prevent huge damages. According to the present invention, the high-specific gravity concrete composition comprises 23.0-43.0 wt% of fine aggregate (S), 23.6-32.0 wt% of coarse aggregate (G), 15.1-17.0 wt% of mixed cement (C1), 10.0-15.0 wt% of red clay powder (C2), 4.2-7.0 wt% of water (W), and 4.1-6.0 wt% of an AD admixture (AD); and has a unit volume weight of 2,801-2,809 kg/m^3 and a compressive strength of 35-43.9 MPa.
본 발명은 해양 콘크리트 구조물 제작 설치 및 보강 작업에 필요한 고 비중 콘크리트 조성물을 제공함으로써, 급격한 기후변화에 대비하고 막대한 피해들을 예방할 수 있는 해양 콘크리트 구조물용 고비중 콘크리트 조성물로서서, 총 중량에 있어서, 잔골재(S) 23.0wt%~43.0wt%, 굵은 골재(G) 23.6wt%~32.0wt%, 혼합 시멘트(C1) 15.1wt%~17.0wt%, 황토 분말(C2) 10.0wt%~15.0wt%, 물(W) 4.2wt%~7.0wt%, AD 혼화재(AD) 4.1wt%~6.0wt%로 구성되며, 단위 용적 중량 2,801kg/m~2,809kg/m, MPa 35~43.9의 압축 강도를 이루도록 구성되는 것을 특징으로 한다.
