Abstract

The purpose of the study is to evaluate engineering properties of Ferro Nickel Slag (FNS) and to investigate the effects of FNS on potential contamination of surrounding soil and water through small and large chamber tests. Soil conditions in the chamber tests were made as closely as possibile to the field conditions. In order to simulate different types of water, we used fresh water, acidic water and seawater. Sand soils were made with relative densities of 40% and 60%, and clay with the degree of compaction of 90%. After flushing water through the FNS in the chambers was completed, the PH test was performed for the water flowing out of the chambers and the soil samples were collected for soil pollution analysis. Based on the results of the chamber tests, although the pollution level was slightly higher in the silt than in the sand, the environmental effect that FNS causes the surrounding soil was found to be very minimal. This indicates that FNS can be used as construction material in place of natural aggregates.

본 연구에서는 FNS의 공학적 특성을 평가하고, 소형 및 대형 모형토조를 통하여 원지반과 유사한 조건으로 FNS 매립시에 주변토양에 미치는 환경적 영향을 평가하고자 하였다. 주입액은 담수, 산성, 해수를 사용하였으며 모래와 실트시료를 사용하여 각각 상대밀도(40%, 60%)와 다짐도(90%) 조건을 선정하여 실험하였다. 소형 및 대형 모형토조에서 배출되는 용출액은 pH 분석을 실시하였으며, 주입이 완료된 후에 샘플을 추출하여 토양오염분석을 수행하였다. 그 결과, 모래보다 실트에서 pH의 오염도가 더 높게 나타남을 확인할 수 있었고, FNS가 주변 토양에 미치는 환경적 영향은 미미한 것으로 나타나 향후 천연골재 대체재로 활용 가능할 것으로 판단된다.
