“…These results proved that leachable metals in the contaminated sediment were effectively immobilized by the C-S-H gel and hydration products, which provided microporous structure and high surface area for metal sequestration. From the perspective of recycling, the sediment blocks were technically plausible, yet long-term leaching should be scrutinized under repeated drying-wetting cycles and increased solution acidity as highlighted in recent studies (Tsang et al, 2013;Li et al, 2014).…”

“…A new remediation strategy that utilizes agricultural/industrial by-products for soil stabilization has captured extensive interests in recent years (Moon et al, 2013;Tsang et al, 2013). This can be regarded as ''green remediation'' in a broad sense, because such approach addresses the problems of contaminated soil/sediment while enabling resource recycling and mitigating the overall environmental impact (e.g., carbon footprint and landfill disposal) associated with solid waste management (Tomasevic et al, 2013;.…”

“…AMDS는 산성이 강하고 중금속함량이 높은 산성광산배수(Acid mine drainage, AMD)를 중화제 또는 침전제를 이용하여 처리한 뒤 남은 찌꺼기(슬러지)를 의미한 다. AMDS의 특성은 AMD 원수의 특성과 그 처리과정에 의 해 결정되지만 (Sibrell et al, 2009;Kim et al, 2012), 일반 적으로 칼슘, 철, 알루미늄 등의 금속들이 거대 또는 미세한 크기의 입자로 침전되어 금속산화물(수산화물) 형태로 존재하 며 넓은 표면적과 많은 작용기를 갖는 것으로 알려져 있다 (Sibrell et al, 2009;Ruihua et al, 2011;Tsang et al, 2013). 최근 이러한 AMDS의 특성을 활용한 환경 분야에서 AMDS의 재이용에 관한 연구가 여럿 진행되고 있다.…”
