- Abstract
- 프리캐스트 콘크리트에서는 적정 품질과 강도를 확보하기 위하여 증기양생을 실시한다. 그러나 이는 많은 CO2 및 비용 등 많은 문제점을 일으킨다. 따라서 본 연구에서는 조기강도를 확보하여 증기양생을 생략함에 따라 감소된 CO2 및 경제성을 분석하였다. 그 결과 재령 6시간에 13.2MPa 압축강도가 발현됨으로써 증기양생 없이도 거푸집 탈형이 가능한 것을 알 수 있었으며 증기양생을 생략함으로써 CO2가 19.8% 감소되었고, 경제성 또한 12% 감소하였다.
In Precast Concrete‘s construction, steam curing is proceeded to get strength but it causes much CO2 and high cost. Therefore, early compressive strength is shown, CO2 reduction and economic can be analyzed. On the result, by getting early compressive strength with 13.2mpa for 6hr, removal form can be realized. Therefore by skipping steam curing, CO2 was reduced as much as 19.8%, and cost also was decreased as much as 12%
