Composite for mine liner having accelerator and preparing method thereof
The present invention relates to an accelerating agent-containing mine liner and cover material composition, which contains 60 to 65 wt% of aggregate; 32 to 37 wt% of a binder; and 0.01 to 3 wt% of a fluidizing agent, wherein the binder contains 5 to 8 wt% of an accelerating agent based on 100 wt% of the total amount of the binder. Therefore, it is possible to prevent the movement of harmful metals and organic substances by installing a wastewater layer in an abandoned mine.
본 발명은 골재 60 내지 65 중량%; 바인더 32 내지 37 중량%; 및 유동화제 0.01 내지 3 중량%를 포함하되, 상기 바인더는 전체 100 중량%에 대하여 5 내지 8 중량%의 급결제를 함유하는 것을 특징으로 하는 급결제 함유 광산 차수재 조성물에 관한 것이다. 따라서 휴폐광산에 차수층을 설치하여 유해금속 및 유기물질의 이동을 방지할 수 있다.
