초록

본 연구는 국내에서 다량 발생하는 제지회사 슬러지의 처리 및 처분을 효율적으로 처리함과 동시에 recycling 하기 위하여 제지회사에서 발생하는 제지슬러지를 소각하여 paper sludge ash를 건설자재 재료로의 재활용 가능성을 파악하여 기존의 건설자재인 시멘트 및 고령토등과 혼합하여 성형 제작후 양생 과정 등의 공정과정(mixing, moulding, drying, demoulding, curing) 을 거쳐 무소성 블록으로 제작한 결과 PSA 첨가율 20%까지 첨가 가능한 것으로 나타났다. 건설 자재화로 재활용함으로써 환경적으로는 폐기물처리 및 재활용, 경제적으로는 처리비용 및 건설자재비용 절감효과, 기술적으로 개발에 의한 해외기술 이전을 가능하게 하여 환경기술개발을 통한 경제적 이익 창출이 가능한 연구결과로 나타났다.

영어초록

The method of recycling through the application of the paper manufacturing sludge generated in our country is to be utilized at non-incinerated recycling. Most of the paper manufacturing sludge is comprised of inorganic material with high content of moisture, and if this is transformed into the form of ash through incineration, the reduction of volume and uniformity of particle can be secured. The study was progressed by forming the shape of block with the application of cement in which incinerated material of paper manufacturing sludge is utilized as general architectural and construction material. In addition, the ratio of optimum addition quantity of incinerated material(Ash) of paper manufacturing sludge for each kinds of binder was compared by applying special cements, i.e., Ultra High-Early-Strength Cement and Micro-Cement rather than using Ordinary Potland Cement only, and the physical property in the case of mixing and using the cement binder only after mixing, forming, and curing time the standard sand, one of the kinds of aggregate, was compared and analyzed.
In addition, the ratio of optimum addition quantity of incinerated material(Ash) of paper manufacturing sludge for each kinds of binder was compared by applying special cements, i.e., Ultra High-Early-Strength Cement and Micro-Cement rather than using Ordinary Potland Cement only.
More over, the study was also compare and analysed by the physical property. The addition rate of PSA results added up to 20~30% was found to be reusable.
