Beschreibung
Zusammenfassung:	The present invention provides a cement slurry composition having excellent toxicity removal effects, and a barrier cement structure using the same. A cement slurry composition comprises Portland cement, nano-Mackinawite (nFeS), cyano-cobalamin (Cbl(III)) and water. A chlorinated organic compound can be reduced and decomposed by an interaction of cement and nFeS-Cbl(III). 시멘트 슬러리 조성물은 포틀랜드(Portland) 시멘트, 나노막키나와이트(nano-Mackinawite: nFeS), 시아노코발라민(cyano-cobalamin: Cbl(III)) 및 물을 포함한다. 시멘트 및 nFeS-Cbl(III)의 상호 작용에 의해 염소계 유기 화합물이 환원성 분해될 수 있다.
