| Zusammenfassung: | The present invention relates to a composition for a mine liner, comprising: cement; fly ash of a circulating fluidized bed combustion boiler; and bottom ash, wherein the fly ash and the bottom ash are fixated with carbon dioxide. Therefore, the fly ash and the bottom ash of the circulating fluidized bed combustion boiler having relatively low commercial values due to high calcium oxides composition are used for a use of the mine liner at a very low cost.
본 발명은 시멘트, 순환유동층 보일러의 비산재(fly ash), 및 바닥재(bottom ash);를 포함하되,상기 비산재 및 바닥재는 이산화탄소가 고정화(fixation)된 것을 특징으로 하는 광산 차수재 조성물을 제공한다. 따라서 높은 산화칼슘 성분으로 상업적으로 가치가 낮은 순환유동층(circulating fluidized bed combustion) 보일러 비산재(fly ash)와 바닥재(bottom ash)를 사용하여 매우 저 비용으로 광산 차수재로 활용할 수 있는 장점이 있다. |
