中文摘要 |
本研究以轉爐石及燃煤飛灰等富含矽鋁酸鹽礦物之工業副產物作為主要研究材料,透過取代水泥及天然粒料的方式,並施作工程力學、耐久性及膨脹率等試驗,開發非結構用透水混凝土磚材,配合國家標準規範檢驗轉爐石混凝土磚材應用於實務上之可行性。研究結果顯示,透水混凝土選定三種不同填漿量,並以轉爐石混拌飛灰取代水泥做為漿料,轉爐石混拌料取代水泥量越多,其抗壓強度成長率較高,根據試驗結果篩選出通過CNS 14995滲透性規範之配比,並根據規範進行強度分級,通過A級抗壓強度標準(28 MPa)者為漿骨比0.4轉爐石混拌料取代量30%;通過B級抗壓強度標準(24.5 MPa)者為漿骨比0.5轉爐石混拌料取代量50%。因此,本研究所提出的配比具有日後實際開發為透水混凝土磚之潛力。 |
英文摘要 |
This study develops a non-structure-used pervious concrete brick using the industrial by-products, such as BOF and fly ash. Experiments regarding the mechanical properties, durability, and swelling are conducted to assess the practical use of BOF based on the national regulations on the concrete bricks. Three different slurry-aggregate ratios are tested with replacing cements by the BOF-FA mixing material. Experimental results indicate that the uniaxial compressive strength growth rate increases as the increasing BOF-FA mixing material. Samples with the proportions which satisfy the permeability specification (CNS 14995) are classified base on the uniaxial compressive strength. The proportion with the slurry-aggregate ratio 0.4 and the replacement amount of BOF-FA mixing material 30% passes criteria of the A-grade (28 MPa). The proportion with the slurry-aggregate ratio 0.5 and the replacement amount of BOF-FA mixing material 50% passes the criteria of the B-grade (24.5 MPa). Therefore, the compound ratio proposed in this study has high potential to put pervious concrete bricks into practice in the future. |
