고강도 콘크리트 적용에 의한 철근콘크리트 구조물의 환경부하 저감에 관한 연구

Abstract

Recently, the construction of super tall buildings utilized by high strength-concrete in the whole world is tending to be on the rise. The application of high-strength concrete in buildings results in the excellent cut-down effect in construction materials due to section reduction and long-life in view of durability. Therefore, in order to investigate the LCCO2 reduction effect and economical evaluation for the reinforced concrete structures with high-strength concrete, comparisons of LCCO2 in life cycle of building structures between high-strength concrete and normal-strength concrete have been performed. As a result, It is concluded that reinforced concrete structures with high-strength concrete showed the LCCO2 reduction effect by 4.12% in construction step and by 1.12% in whole progress of 40 years, compared to RC structures with normal-strength concrete and had also the economical benefits of 2.76 million dollars during 40 year-life cycle.
