中文摘要 本研究探討改質後之水庫淤泥添加至水泥砂漿中,對於水泥砂漿水化速率及工程性質之影響。選擇水灰比為0.5及0.7之水泥砂漿,分別添加5%、10%、15%及20%之改質水庫淤泥,並添加木質素及消泡劑改善水泥砂漿之工程性質,試驗結果顯示改質水庫淤泥並不影響水泥砂漿之水化速率,但由於改質水庫淤泥之群聚現象,導致拌合過程中產生大量氣泡,降低水泥砂漿之抗壓強度,故利用添加木質素及消泡劑,並改變拌合順序,有效地改善改質水庫淤泥之群聚現象,進而提升水泥砂漿之抗壓強度。雖然改質水庫淤泥之群聚現象所導致大量氣泡生成,影響水泥砂漿之抗壓強度,但因改質水庫淤泥之特殊防水機制,使水泥砂漿具良好之抗滲性,因此,將添加改質水庫淤泥之水泥砂漿應用於防水水泥砂漿粉刷中,獲得良好之防水效果。
英文摘要 The effects of organo-modified reservoir sludge (OMRS) on the hydration rate and engineering properties of cement mortars are evaluated here. Various dosages of OMRS, 5%, 10%, 15% and 20%, were considered in producing cement mortar specimens with different water/cement ratios of 0.5 and 0.7. At the same time, lignin and foam-reducing agent were used to improve the engineering properties of cement mortars with OMRS. Experimental results indicate that the effect of OMRS on the hydration rate of cement mortars is insignificant. However, a large amount of foam typically formed during blending due to the clustering of OMRS is observed, leading to a decrease of the compressive strength of cement mortars. The clustering of OMRS and the compressive strength of cement mortars with OMRS can be effectively improved if lignin and foam-reducing agent are adequately added and the order of blending is properly changed. It is also found that the water-proof mechanism of cement mortars with OMRS is effective and their permeability can be significantly reduced as compared to those without OMRS. As a result, the use of OMRS to provide the water-proofing mechanism in cement mortars is promising.
