本研究採用焚化飛灰掺合水庫淤泥、廢玻璃等材料，進行造粒與燒結，探討垃圾焚化飛灰製造輕質粒料的可行性。首先進行原料的成分分析、XRD物種分析、重金屬總量與TCLP溶出分析及DTA/TGA分析等，作為造粒配方之依據，以重量比0%~50%焚化飛灰添加90%~50% 掺合料，共計超過40組配方，進行造粒及燒結，採用可程式高溫爐、電熱式旋窯與瓦斯燃燒式旋窯三種燒結儀器，溫度控制在1000℃~1150℃間。燒結後粒料即進行比重、吸水率、粒徑變化、重金屬總量與TCLP溶出、鬆容重、點壓強度、筒壓強度、成分分析、XRD分析與SEM/EDS等定性定量分析。結果顯示，各種配方在溫度超過1100℃後，粒料之重金屬溶出值均符合法規值。高溫爐在1130℃~1140℃所燒結之粒料，可獲得良好的工程性質，而旋窯所燒結之粒料品質變異較大，而(10%~30%)低比例焚化飛灰使用量之粒料有良好的工程特性質。輕質混凝土採用三種水膠比進行新拌、硬固與耐久性質等檢測，建立輕質粒料混凝土之資料庫。結果顯示，10~30%比例焚化飛灰輕質粒料，所製輕質混凝土的工程性質較常重混凝土佳，同時也顯示焚化飛灰輕質粒料可製成良好的耐火材料。

The municipal waste incinerator fly ash is mixed with sediments from reservoir and waste glass to study the possiblity of producing lightweight aggregate (LWA). After carried out XRF and XRD analysis, total heavy metal content and dissolve TCLP analysis, and DTA/TGA analysis of each individual material, ingredient formula can then be selected for pelletizing and at least 40 mixes are obtained with 10~50 wt% trash fly ash and 90~50 wt% additive material. After pelletized, the LWA is sintered under temperature of 1070~1150℃ by electric furnace, the electric rotary kiln and the gas rotary kiln. The produced LWA is then proceeded to check the properties of specific gravity, the water absorption capacity, the diameter change, the total heavy metal content and dissolve TCLP, the dry loose density, the point load, the tube pressure, the chemical analysis, the XRD analysis and the SEM/EDS observation. The result showes once the sintering temperature above 1100℃ the heavy metal dissolve content of LWA is lower than the regulation. The LWA produced by electric muffle furnace with temperature of 1130℃~1140℃ has good engineering property, and LWA sintered by rotary kiln has large variation except that with low ash content (10%~30%) has good engineering property. The lightweight concretes (LWC) with LWA and three kind of water-to-binder ratio are mixed to build the data bank of fresh, harden and durability. It also shows that LWC with 10~30% ash LWA performs better than normal concrete, and ash LWA can be used to produce high quality fireproofing material.
