본 연구에서는 $CO_2$ 배출 저감을 위한 저탄소 콘크리트 구조물 설계 절차를 제시하였다. 전과정 $CO_2$ 평가에 기반한 저탄소 콘크리트 구조물 설계 절차는 ISO 13315-2에서 요구하는 시스템 경계를 이용하였으며 구조물의 전과정 평가를 수행하기 위한 전과정 목록(life-cycle inventory, LCI)은 기본적으로 국가에서 구축한 LCI 데이터베이스 정보망을 이용하였다. 본 연구에서 제시한 절차에 따라 전단벽 콘크리트 구조물을 대상으로 전과정 $CO_2$ 평가에 대한 사례분석을 수행하였다. 기둥부재의 경우 GGBS 25% 치환 시 재료단계, 해체 및 파쇄단계, 운송단계에서 $CO_2$ 발생량 및 탄산화에 의한 $CO_2$ 포집량은 모두 감소하는 것으로 나타났으며 OPC 대비 약 26% 감소하는 것으로 나타났다. 기둥, 벽체, 보 및 슬래브 전체의 경우 GGBS 25% 치환에 따라 전과정 $CO_2$ 발생량이 약 22% 저감하는 것으로 나타났다. The objective of this study is to present the design approach of low $CO_2$ concrete structures for reduction of $CO_2$ emissions. The design approach was implemented considering the system boundary for each processing presented in the ISO 13315-2. As for life-cycle inventory(LCI) for $CO_2$ assessment of concrete structures, data provided from domestic LCI DB was used. Based on the process presented in this study, case studies on the life-cycle $CO_2$ assessment of shear wall concrete structure was conducted. As substitution level of GGBS is 25%, the amount of $CO_2$ emissions and $CO_2$ uptake by concrete carbonation was decreased in the material, demolition and crushing, and transport phase. The amount of $CO_2$ emissions of column and total member was decreased by 26% and 22% respectively, compared to that of OPC.

As the building becomes super-higher recently, it is necessary to measure horizontal movement of building precisely. The more the altitude of the building is highly, the more method using total station is a limit of measurement. The method using total station is impossible while it rains and it is difficult to acquire the visual field for measurement if the altitude of the building is more high. Consequently research laid the plan to overcome the critical point of measurement technique using total station. It evaluated the construction application possibility in the filed with development of system to manage the horizontal movement of the formwork using GPS. Analysis result of measuring data in the filed at once is a within the error scope 10㎜ with horizontality. So it will be able to secure the reliability of the measuring coordinate point to use GPS. If reducing establishment of a measuring equipment and a data processing velocity, it will be able to secure more accurate and quick data. It is possible to apply horizontal movement management in construction building using GPS and it will be able to overcome vertical degree management limitation of construction building using total station in the case of super high-rise building project through out GPS.
