The present invention relates to a solidifying composition for improving soil on weak ground having high water contents by using reduction slag, and a method for solidifying soil by using the same and, more specifically, to a solidifying composition for improving soil on weak ground having high water contents, comprising 10-30 wt% of reduction slag; 35-50 wt% of first class general Potland cement; 20-50 wt% of a fine blast furnace slag powder; and 1-30 wt% of gypsum, and the method for solidifying soil comprising the step of solidifying soil by using the composition. The solidifying composition provided in the present invention does not cause civil engineering and environmental engineering problems and especially improves and enhances soil on weak ground having high water contents with excellent efficiency. 본 발명은 환원슬래그를 이용하여 고함수율 연약지반 토양의 개량을 위한 고화재 조성물과 이를 이용하여 토양을 고화하는 방법에 관한 것으로, 보다 구체적으로는 환원슬래그 10~30 중량%, 1종 보통 포틀랜드 시멘트 35~50 중량%, 고로슬래그 미분말 20~50 중량% 및 석고 1~30 중량%를 포함하는, 고함수율 연약지반 토양 개량용 고화재 조성물과, 상기 조성물을 이용하여 토양을 고화시키는 단계를 포함하는, 토양의 고화 방법을 제공한다. 본 발명에서 제공하는 고화재 조성물은 토목공학적 및 환경공학적 문제를 발생하지 않고, 특히 고함수율 연약지반의 토양을 우수한 효율로 개량 및 강화시킬 수 있다.
