中文摘要 | 本文針對國內主要水庫庫底抽砂產生之淤泥,尋求再利用之可能途徑,以解決各 水庫淤泥處理的因難。進行之方法係在實驗室內利用少量的水泥、飛灰或細砂與大量的水庫 淤泥加水拌合,製成具有良好流動性旳泥漿填料,並分別測試各不同配方泥漿之流動性凝結 時間、泌水性、單位重及強度發展等特性,以評估水庫淤泥製作流動性填料之可行性。實驗 結果顯示採用波特蘭第一型水泥配合飛灰與水庫淤泥拌合製成之流動性填料,具有良好的流 動性及合理的強度,可應用於管槽回填、擋土牆背填、及地下結構物封填等場合,研究成果 可提供國內各水庫處理淤泥及再利用之參考依據。 |
英文摘要 | Due to land use limitation and stringent environmental regulations, the disposal of reservoir sedimentation has become more and more difficult. On the other hand the supply of quality soil and aggregate materials for construction has diminished significantly in Taiwan. The utilization of reser-voir sedimentation not only solves a waste disposal problem but also provides an economic construc-tion material. The purpose of this study was to assess th epossibility of mixing reservoir sedimentat-ion with cement and/or fly ash to make a flowable material for applications in trench backfill, retaining wall backfull, and underground void filling. Laboratory investigations were conducted on the sedimentation collected from a reservoir in northern Taiwan, Physical properties included speci-fic gravity, organic consistency constants were determined. Mixtures consisting of sedimentation, cement, fly ash, and water ere tested for their setting time, bleed, flowability, unit weight, as well as strength development characteristics. |
