    摘要: 「礦尾渣」為杜邦公司工業生產衍生的副產品,與水泥拌合後凝結硬固成為「鈦鐵礦氯化爐碴」。目前鈦鐵礦氯化爐碴已再利用於道路基底層。其特性為經滾壓後有再膠結現象及含有大量氯離子,此試驗分別研究鈦鐵礦氯化爐碴再膠結的強度發展及水洗前處理礦尾渣。 試驗結果顯示,鈦鐵礦氯化爐碴經壓實後的抗壓強度或C.B.R.值,都有明顯隨齡期發展的趨勢。鈦鐵礦氯化爐碴有良好的體積穩定性,縱使在高溫狀態下或長期浸水膨脹率都符合並遠低於規範要求。 水洗前處理礦尾渣可有效降低水溶性氯離子含量。經由膠體沉降時間試驗結果發現,硫酸鋁及硫酸鐵其混凝效果較佳。添加碳酸鈉對水洗礦尾渣,能提高氯離子被溶出量,增加水洗成效。基本水洗(過濾)方式成效較佳。水洗後礦尾渣吸水率高於天然砂石甚多,所以水 泥礦尾渣砂漿流度值,會隨著高吸水率之礦尾渣用量增加而降低。 SCDS is one of the by-products produced by the DuPont Co., Ltd. After mixing with cement it is coagulated into TCS. Currently TCS is being adapted for pavement. It is re-glued and contained of a certain amount of chlorine ion. This experiment is aimed at the intensity of titanium iron chloride and the SCDS before water-wash. The result shows that the intensity and compression resisting or C.B.R. is enormously increasing with its sequence. TCS is very stable, it status is under the regulated standard even under high-temperature or after a long-time of soaking in water. Before the washing the SCDS, we can efficiently decrease the water chlorine ion. After the experiment of colloid subsiding, we found that aluminum sulfate and iron sulfate have better concrete result. Adding in calcium carbonate when washing SCDS can increase the chlorine ion’s dissolving. Basic washing (filtering) approach is more effective. After washing, the SCDS absorbs much more water than regular sand. Therefore the flowing rate of concrete SCDS is increasing when the use of SCDS with high absorbing intensity’s increasing.
