The LCCO2 REDUCTION EFFECT AND ECONOMICAL EVALUATION OF THE REINFORCED CONCRETE STRUCTURE USING HIGH-STRENGTH CONCRETE

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(RC) 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 RC structures with high-strength concrete showed the LCCO2 reduction effect by 4.12% in construction step and by 1.12% in whole progress of 60 years, compared to RC structures with normal-strength concrete and had also the economical benefits of 2,760 thousand dollars during 60 year-life cycle.
