Abstract

The industrial waste is becoming a big problem in the aspect of spatial and environmental in domestic and international. Therefore, the waste reduction and recycling policy has been being implemented as a way to solve this problem. The engineered stone sludge, which is waste, is generated duing the engineered stone production process. since engineered stone sludge is mostly treated by landfill, an increase in the amount of the sludge leads to an increase in landfill sites and treatment costs. therefore, there is a need for a method of resourcization with engineered stone sludge. So, laboratory tests (Plastic and liquid limits, compaction, unconfined compression and permeability test) were conducted to confirm the possibility of using engineered stone sludge mixed with weathered granite soil as a cover material for landfill in this study. The result shows that the mixed soil material with less that 62.5% of engineered stone sludge can be used as a cover material for landfill.

산업폐기물은 국내외적으로 공간 및 환경적 측면에서 큰 문제가 되고 있다. 따라서 이를 해결하려는 방법으로 페기물 감량화 및 재활용 정책이 실시되고 있다. 산업폐기물인 엔지니어드스톤 슬러지는 엔지니어드스톤 생산 과정에서 발생한다. 엔지니어드스톤 슬러지는 대부분 매립으로 처리되기 때문에 발생량 증가는 매립공간 및 처리비용을 증가시킨다. 그러므로 엔지니어드스톤 슬러지를 자원화 시킬 수 있는 방법이 필요하다. 이에 본 연구에서는 엔지니어드스톤 슬러지에 화강풍화토를 혼합한 혼합 복토재를 매립지의 복토재로서 활용 가능성을 확인하기 위한 목적으로 실내시험(액소성시험, 다짐시험, 일축압축시험, 투수시험)을 수행하였다. 그 결과 엔지니어드스톤 슬러지의 함유량이 62.5% 미만인 엔지니어드스톤 슬러지 혼합 복토재가 매립지의 복토재로 활용할 수 있을 것으로 판단된다.
