Abstract:	本研究利用都市焚化爐底渣、飛灰來製作綠建材透水地磚。因社會進步垃圾也隨之增加，焚化爐燃燒後產生的底渣、飛灰造成環境問題，研究如何解決這些底渣、飛灰刻不容緩。在研究各國的論文後，發現在透水材料方面將焚化爐底渣、飛灰再利用的研究，是以將焚化爐底渣、飛灰製作成澆注型透水混凝土為研究大宗。所以此研究將方向定往以使用焚化爐底渣、飛灰用燒製法來製作綠建材透水地磚。將焚化爐底渣、飛灰拿回來進行粉碎、添加黏結劑進行攪拌，使用C型沖床進行成型將生胚燒結產生成品。完成吸水率、視氣孔率、滲透係數和抗壓強度測試。在使用配比C原料比例42%爐底渣、10%飛灰、20%黏結劑C、10%可燃物質、17%骨材與1%助熔劑的試驗結果，吸水率的平均為11.65%、視氣孔率的平均為20.84%、滲透係數的平均為0.014cm/s、抗壓強度的平均為175.99kgf/cm2，除了吸水率有些微差異外其餘都達到台灣高性能透水綠建材的單元透水磚透水鋪面標準。 This study utilizes municipal incinerator bottom ash and fly ash to create green permeable paving bricks. With societal progress, waste generation has increased, and the bottom ash and fly ash produced by incinerators pose environmental problems. Addressing these bottom ash and fly ash issues is urgent. After reviewing international research papers, it was found that most studies on reusing incinerator bottom ash and fly ash in permeable materials focus on making cast-in-place permeable concrete. Therefore, this study aims to use incinerator bottom ash and fly ash to produce green permeable paving bricks through a firing method. The process involves crushing the incinerator bottom ash and fly ash, adding a binder, and mixing. The mixture is then shaped using a C-type punch press, and the green body is sintered to produce the final product. Tests were conducted on water absorption, apparent porosity, permeability coefficient, and compressive strength. Using the mix ratio C with 42% bottom ash, 10% fly ash, 20% binder C, 10% combustible material, 17% aggregate, and 1% fluxing agent, the results showed an average water absorption of 11.65%, an average apparent porosity of 20.84%, an average permeability coefficient of 0.014 cm/s, and an average compressive strength of 175.99 kgf/cm². Except for a slight deviation in water absorption, all other results met the standards for high-performance permeable green building materials for unit permeable bricks in Taiwan
