| 中文摘要 | 本文針對中南部所產生地磚「黑斑」問題,經由「望」「聞」「問」「切」病理診斷過程,利用科學儀器,進行病理分析,探討地磚冒「黑斑」的來龍去脈,尋求預防之道及改善策略。診斷過程配合巨微觀測定方法,分析「黑斑」成份並切入混凝土,鑽心取樣剖析材質以找出病變原因。結果指出地磚孔隙率偏高導致濕氣作用,推論係地磚冒出黑斑之主因。預防之道包括:(1)慎選施工材料,(2)採用正確施工方法,(3)研擬標準施工說明書等。 |
| 英文摘要 | Based on the black spotes problem happening in some community, this study is to inspect the reason and procedure resulting in the black spots on bricks, and find out the prevention way and solution policy through the scientific instrucments and pathological analysis. Macro/micro examining system will be applied to analyze the ingredient of spots. Simultaneously, core drill sampling method is used to analyze the material quality of concrete to figure out the reasons causing degradation. Results indicate that the high pore ratio of bricks will generate the humidity effect, and it is one of the factors to cause spots. In addition, sand used for construction containing higher alkaline substances, such as calcium and potassium, will generate the gel of alkaline-silicate reaction. This gel is inferred to be the main reason to cause the formation of spots. The suggested preventions include: (1) carefully choosing construction materials; (2) Adopting correct construction methods; (3) preparing standard construction menu, etc. |
