Abstract

The purpose of this study is to provide the ways of recycling of by-product limes as lightweight fill, backfill materials, and lightweight blocks by performing experimental study. New lightweight fill materials and blocks were devised by mixing by-product lime, weathered granite soil, small pieces of waste EPS, and Portland cement. Physical, geotechnical, and environmental properties of the lightweight mixed soils and blocks were analysed by laboratory experiments for mixed samples manufactured with various mixing ratios. KMS tests were also performed to evaluate the concentration variation of the chemical components of the light weight blocks leachates. It is expected that this study will contribute to resolving the problem of by-product lime disposal as well as to recycling the by-product limes as fill materials and blocks.

본 연구에서는 석회부산물의 재활용 방안으로 경량성토재, 뒤채움재 및 경량블록의 활용방안을 종합적인 실험연구를 통해 수행하였다. 이를 위하여 본 연구에서는, 석회부산물, 성토용 토사 및 폐 EPS 조각을 혼합한 새로운 형태의 경량성토계 및 이에 시멘트 고화제를 첨가한 경량블록을 고안하였고, 다양한 배합비로 제작된 경량혼합토 및 경량블록에 대한 시료에 대하여 종합적인 시험을 실시하여 물리적, 지반공학적 및 환경적 특성을 분석하였다. 또한 경량블록에 대하여 국내 용출시험법(KMS Method)을 실시하여 화학성분의 농도변화에 대하여 평가하였다. 본 연구는 석회부산물 처분의 문제에 대하여 해결을 기대할 수 있으며 뿐만 아니라 성토재 및 블록에 대하여 석회부산물의 재활용 방안을 기대할 수 있다.
