The study on annual evaluation of CO₂ and general economic for precast concrete without steam curing

증기양생이 불필요한 프리캐스트 콘크리트의 연간 CO₂ 저감량 및 경제성 평가

Nowadays, Precast Concrete is adopted on most of construction, because of shortening construction period and good quality. In precast concrete, steam curing is necessary for getting proper strength, but it causes much CO₂ and economc. Therefore, on this study, by using type III cement and hardening accelerator, early compressive strength was shown 13MPa for 6hr. From the result, removal form could be shorten. Furthermore, annual CO₂ was reduced as much as 24% and also annual cost was decreased as much as 12%.
