台灣是個天然資源匱乏的小島國家，為了解決天然資源不足問題，須積極尋找及開發更好的資源回收再利用技術。目前台灣各港口地區為了港口營運與船舶航行所需，每年需固定清除百萬噸港灣淤泥，但國內尚缺乏疏浚後浚泥的更妥善處置方法，故大多以海洋棄置處置。因應未來海洋棄置法規日益趨嚴，現今國際間積極開發浚泥再利用處理技術，其中混拌技術因選擇材料大多為另一種廢棄物或工業副產物，基於資源回收再利用角度，相信是未來再利用技術應用的趨勢。然而，港灣浚泥因泥質成份較高、承載強度較低，若要再利用於工程方面，需添加其他具有高工程強度特性的材料，其中煉鋼副產物-轉爐石，因其具有高硬度且礦物組成相似於水泥膠結材料之特性，應可透過浚泥添加轉爐石混拌技術，增加浚泥的工程強度，藉此提高浚泥的再利用性，增加其市場價值，進而降低浚泥海洋棄置量。
本研究的目的是將浚泥添加轉爐石混拌製成再利用材料，並藉由工程適用性與環境相容性試驗，評估混拌材料應用於工程再利用的可能性。研究結果顯示，混拌材料中轉爐石添加量達30%以上時，其載重強度(CBR)可滿足道路鋪面工程基層級配粒料品質的需求，轉爐石添加量達70%時可滿足底層級配粒料品質的規範。另，浚泥添加轉爐石混拌後可增加其抗壓強度，轉爐石添加量超過30%時，所製作的試體抗壓強度明顯高於純水泥試體。而混拌材料應用於骨材替代品時，其轉爐石添加比例不宜超過40%，以避免試體日後發生膨脹龜裂的問題。另一方面，浚泥添加轉爐石混拌材料之重金屬溶出濃度皆低於有害事業廢棄物認定標準且符合道路鋪面級配粒料品質規定，顯示混拌材料於工程再利用上並無毒性重金屬溶出對環境造成污染之虞。

In order to maintain the depth of water channels and wharf for ship navigation, huge amounts of harbor sediments are dredged and dumped into nearby ocean disposal site annually. These dredged sediments are a valuable resource that can be sold for reuse after being processed. However, dredged sediments are difficult to be reused directly for construction because they are mostly consist of high proportion of clay with limited strength, resulting in poor bearing the capacity and easy subsidence. The objective of this study is to enhance mechanical strength and bearing capacity of dredged sediment by admixing with steelmaking byproducts - basic oxygen furnace (BOF) slag. The physical and mechanical properties of the sediment-slag mixtures were examined by Proctor compaction test, California bearing ratio (CBR) test, compressive strength test, autoclave expansion test as well as SEM-EDS and XRD determination. The environmental compatibility of the sediment-slag mixtures was also assessed by toxicity characteristic leaching procedure (TCLP) and pH evolution test.
Results showed that the admixing technique for the reuse of dredged sediments coupled with BOF slag seems to be feasible. Dredged sediments admixed with BOF slag can effectively strengthen its bearing capacity and mechanical strength. When the admixing proportion of BOF slag reaches more than 30%, the CBR and compressive strength of the sediment-slag mixtures show a significant increase that was strong enough as aggregates for construction. In order to avoid the cracking problem caused by hydration-expansion, the admixing proportion of BOF slag in the sediment-slag mixtures should be kept lower than 40%. Toxicity characteristic leaching procedure extracts heavy metals from the sediment-slag mixtures at negligible levels.
