CO2 배출량 및 흡수량을 중심으로 한 콘크리트의 친환경성능 평가에 관한 문헌적 연구

Abstract

본 연구에서는 시멘트 콘크리트 산업에서의 CO2 배출량과 콘크리트 탄산화에 의한 CO2 의 흡수량을 기존 문헌연구를 통하여 개산적으로 검토하는 것에 의해 시멘트?콘크리트 산업의 본질적인 CO2 배출량 및 흡수량에 대한 자료를 제공하고자 한다.

A cement which is used in construction and a concrete which is a hydration product of cement is considered anti-environmental materials because of lots of CO2 emission in progress of producing and making them. But a concrete absorbs the CO2 gas in atmosphere after hydration and in its lifetime. Based on Papadakis’ theses, this research is carried on calculation of the CO2 absorption quantity in concrete. Also, the emission of CO2 was calculated by cement manufacture. As a result, It is said that the CO2 which was emitted during cement manufacturing, was absorbed the 53% of emission quantity by the carbonation of concrete.
