論文題目(中): UHPC水溝蓋添加垃圾焚化灰渣之初步研究
論文題目(英): The Preliminary Study of Making the UHPC Ditch Cover with Trash Ash
摘要(中):
近年來因經濟與工商業的迅速發展,同時衍生出許多問題,一方面是鋼鐵需求量逐年增加,其鋼鐵價格不斷向上攀升,使得道路上的水溝蓋也不斷地遭偷竊;另一方面為廢棄物處理的問題,預估每年平均會產生200萬噸的一般垃圾,其垃圾大部分均使用焚化爐來處理,但經焚化爐處理後仍有許多的焚化灰渣需要掩埋,所以本研究針對以上兩大問題,探討以超高性能混凝土添加水淬熔岩或垃圾焚化飛灰來取代超高性能混凝土中之水泥或石英粉,並製作水溝蓋進行相關研究。試驗項目包括:力學性質試驗、8孔水溝蓋載重試驗、TCLP溶出試驗、OM檢測,本研究所預期的水溝蓋載重強度為10 公噸。
試驗結果顯示,水淬熔岩或垃圾焚化飛灰替代水泥之抗壓強度有大幅下降,而水淬熔岩或垃圾焚化飛灰替代石英粉之抗彎強度僅稍微下降。在製作添加10%或15%水淬熔岩或垃圾焚化飛灰之UHPC水溝蓋其載重強度均可達到10公噸要求,但水溝蓋表面因添加垃圾焚化飛灰而呈現腐蝕現象。由TCLP結果顯示超高性能混凝土可以藉著材料的緻密性,有效抑止重金屬溶出,其中錳、鎘、鋅效果較為明顯。
摘要(英):
Economy and industry rapid development in recent year, it simultaneously grows many questions. On the one hand, the steel and iron of demand has increased year by year, the price of steel and iron upwardly climbs. It causes the ditch cover made by cast ton to be stolen and jeopardize passersby and traffic safety. On the other hand, it is the question of waste processing. Two minion tons of garbage had been produced under evaluation every year. The waste incinerator processed the majority of garbage, but it still had much fly ash as landfill to bury after the waste incinerator processing. Therefore, this study was included in above two major problems. Fly ash from incinerator and water-quenched slag from plasma for part replacement of cement or quartz powder was used as ultra-high performance concrete (UHPC) which might be manufacturing UHPC ditch cover being under discussion. The experimental items included mechanical properties of UHPC, ditch cover with 8 ho1es loading test, TCLP dissolve test, and etc. The standard loading test is 10 tons for the ditch cover.
The results show that the compressive strength of UHPC decreases greatly as fly ash from incinerator or water-quenched slag from plasma for part replacement of cement or quartz powder increases. However, the flexural strength of UHPC decreases a little as fly ash from incinerator or water-quenched slag from plasma for part replacement of quartz powder increases. The results have also found out the UHPC ditch cover with 10% or 15% fly ash from incinerator enough bears 1O tons loading capacity. The corrosion problem on the surface of the UHPC ditch cover was found owing to fly ash from incinerator. The toxicity character leaching experiments (TCLP)test result also indicates that the heavy metal content is under the standard of regulation while adding fly ash from waste 1ncmerator to UHPC. As a result, it is feasible under current regulation requirement to replace part cement by the fly ash from waste incinerator for the UHPC ditch cover.
