Literature Study on the Sustainale Performance of Concrete Focus on the Amount of Discharge and Absorption of $CO_2$ Gas

$CO_2$ 배출량 및 흡수량을 중심으로 한 콘크리트의 친환경성능 평가에 관한 문헌적 연구

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 $CO_2$ emission in progress of producing and making them. But a concrete absorbs the $CO_2$ gas in atmosphere after hydration and in its lifetime. Based on Papadakis' theses, this research is carried on calculation of the $CO_2$ absorption quantity in concrete. Also, the emission of $CO_2$ was calculated by cement manufacture. As a result, It is said that the $CO_2$ which was emitted during cement manufacturing, was absorbed the 53% of emission quantity by the carbonation of concrete.
