| Summary: | 碩士 === 國立臺北科技大學 === 資源工程研究所 === 97 === In Taiwan, a large number of reservoir sludge is an imperative problem that causes reservoir capacity decreasing. Landfill and ocean dumping, and recycling is generally used for treating reservoir sludge at present. For example, the application of bricks, lightweight aggregates and controlled low strength materials. This study evaluated the feasibility of building bricks produced from reservoir sludge using geopolymeric technology. A series of brick green bodies were manufactured by mixing reservoir sludge, glass powder, amorphous metakaolinite powder, alkali silicate solution and alkal hydroxide solution with a certain wt.%. The results show that building bricks made by geopolymeric technology at a thermal treatment range of 300 - 500℃ for 2 hours which conform with Taiwan building bricks criteria. Thus, a large amount of sintering energy can be saved. The mechanical property and water absorption of building bricks can be improved by addition 10 - 20 wt.% glasses or metakaolinite powders. It represents that the production of building bricks can be replaced clay by reservoir sludge and provided a feasible program of recycling management.
