    Abstract: 本研究在發展膠結材料固化污泥以低用水量條件下拌合成塑性漿體再壓製成型的模具及工法研發,並選擇以孔隙率作為製作塑性漿體的控制參數,經相同配比及壓力的30次重覆性試驗進行試體一致性及再現性的檢驗,再進行製磚研究,已證實模具及工法的合適性。研究顯示,發現同一次壓製過程,不同空格位置的試體性質具有一致性;但在不同次壓製時,次別間試體再現性不佳;塑性漿體的上層及下層的試體品質並未顯示一致。以控制孔隙率的概念進行漿體的設計,則所有製成試體的初始孔隙率均會相同,可由孔隙率管制品質。塑性漿體的試驗與設計孔隙率比值及試驗與設計高度比值具有線性關係,實務上可以利用高度作為孔隙率是否符合要求的檢測參數。製磚的壓力需求大於塑性漿體的需要,壓製出磚試驗與設計高度比及試驗與設計孔隙率比之間呈現正相關。利用空隙填漿的概念,可以設計磚的孔隙率,利用孔隙率也可以控制磚的品質,因漿體孔隙率較粒料大,所以設計空隙填漿比增加時,整體磚的設計孔隙率就會隨之增加。;This research is to develop a mold and the making procedures of mixing the plastic paste and making the solidified products by compression for sludge solidified by cementing material at a low water condition. The porosity of plastic paste is choosing as a controlled parameter, after the repetitive tests of 30 with the same mixing proportion and compressing pressure, examine the consistency and reproducibility of the specimen properties, and then making brick. The results have demonstrated the suitability of the mold and the making procedures. The research indicates that the specimen at different position of the mold have the consistent properties for the same compressing process. It is not good for the reproducibility of the pecimen properties between the different compressing processes. And the specimen quality of the upper and lower is not consistent. Using the concept of controlled porosity make the mixing design of plastic paste, the initial porosity of the specimens will be the same. The quality of specimen can be controlled by the porosity. There is a linear relationship between the ratio of the experimental and designed porosities and the ratio of the experimental and designed heights. In practical application, the height of specimen can be an examining parameter to judge whether the porosity meeting the requirements. The demanded pressure for making brick is higher than that of making plastic paste solid. There is also a positive relationship between the ratio of the experimental and designed porosities and the ratio of the experimental and designed heights. Using the concept of voids filling by paste can design the porosity of brick.
