dc.description.abstract | 國內建築與公共工程建設多以預拌混凝土為主要材料,使用量非常龐大,然而在混凝土材料的生產與使用過程中也同時生成許多的溫室氣體與當今環保減碳永續發展的觀念背道而馳。近年來工業廢棄物如煉鋼後所產生的爐石,與燃煤發電後產生的飛灰等都可以作為混凝土組成的相關材料。將這些材料適當加入後,除可以減少混凝土中水泥的使用量外,並可減少二氧化碳產生量與提升混凝土耐久性質,並在增加工業廢棄物的附加價值與再利用性,以達到環保減碳永續發展之目標,減少自然生態環境上之衝擊。 本試驗嘗試將CFB水化灰、脫硫碴、煤灰粒料、廢棄混凝土,四種再生粒料依不同比例搭配並用於CLSM中,將再生粒料取代天然之粗細粒料。粉體部分則是使用CFB灰,水泥,爐石三種互相組合搭配。組合後本試驗設計了64組不同CLSM之配比,其水膠比均為0.69,而各組配比則有不同之粒料及膠結材之比例,並觀察各組配比是否符合施工綱要規範之要求。 試驗部分各組配比之試驗有:坍流度試驗、落沉試驗、氯離子含量試驗、各齡期之抗壓強度(7、14、28、56天)以及各齡期(1~7、14、28、56天)收縮膨脹試驗。藉此觀察各組配比與控制組之差別及各組配比之間互相的差異,並看各組配比是否符合施工綱要規範對於CLSM之要求。希望能夠由本研究進而觀察再生粒料用於CLSM上之可行性,以達到回收再利用,永續發展之目標。 | zh_TW |
dc.description.abstract | Domestic construction and public works mostly use concrete as the main material, however many of the greenhouse gases generated in the production process of the concrete materialt. In recent years, industrial waste such as the slag, fly ash can be used as the composition of the concrete relevant material to reduce carbon dioxide production and reuse of industrial waste, in order to achieve environmental protection and carbon reduction. This research uses CFB hydration ash, desulfurization slag, coal ash aggregates and waste concrete four different aggregates with different ratios used to produce CLSM. Cementitious materials is made form CFB ash, cement, slag three combinations with each other. 64 different sets of CLSM mix design more tested, water-cement ratio 0.69. Each proportion was tested for complace with the construction specifications. Tests performed for each proportion are: Slump flow test, Ball Drop test, Method of test for the water soluble chloride ion content of fresh concrete, the compressive strength of each age (7,14,28,56 days) and strain test of each age (1 to 7, 14,28,56 days). | en_US |
