摘要:	本研究係以陶瓷業無機性污泥為主要研究對象，進行相關資源化運用之研究，其資源化方向分為兩大部分：製成人工細粒料及作為自充填混凝土之礦物摻料。研究結果顯示，陶瓷業無機性污泥基本特性符合工程規範之基本要求，因此陶瓷業無機性污泥在資源化上運用應是可行無虞。在製成人工細粒料方面，本研究採用自行改良之冷結法進行造粒，且成功生產出人工細粒料，若將人工細粒料取代10 %的天然細粒料拌製砂漿試體，其新拌漿體之流度值、硬固試體抗壓強度、單位重和吸水率，與完全未添加人工細粒料之砂漿試體結果較相近。在自充填混凝土方面，陶瓷業無機性污泥具備比重輕、比表面積大與高吸附水等特性，對工作性有負面影響，但發現添加量佔全礦物摻料20 %時，對水泥漿及水泥砂漿工作性影響較小，故運用此比例拌製成自充填混凝土，以滿足新拌性質之要求。使用本研究之資源化處理方法能大量減少污泥數量，解決污泥造成之環境污染，達成資源利用與廢棄物減量之目標。 This study focuses on the utilization of waste from the ceramic industry to demonstrate their resource optimization application. Its utilization are on two different aspects, as a component in man-made fine aggregates and as material admixture for self-compacting concrete.With regards to its utilization as man-made fine aggregates, cold-bonding method is adopted to produce and process these products. Its use as 10% replacement to natural fine aggregates in mortar has produced flow value, compressive strength, unit weight and moisture absorption similar to those from natural aggregates.When used as material for self-compacting concrete, the light specific gravity, large specific surface area will cause high moisture absorption in cement paste and mortars. However, the influence is reduced by increasing the admixture content up to 20%. The 20% mixture satisfy the fresh concrete application.The utilization for the mentioned application will contribute in decreasing waste and solving environmental contamination. Eventually the goal of resource optimization and waste reduction will be reached.
