中文摘要 隨著世界能源總消耗量逐年增加,與氣候變化有關的問題亦持續增長,建築節能成為受到重視的議題。由於氣凝膠獨特的性質,是一種隔熱效果極好的材料。本研究擬將氣凝膠添加於建築材料中並進行相關試驗,以達到建築節能之目的。本研究的實驗分為氣凝膠的製備以及添加氣凝膠於水泥砂漿兩部分。在氣凝膠的製備上,使用甲基三甲氧基矽烷(MTMS)作為前驅物,透過溶膠凝膠法與常壓乾燥法製成氣凝膠,並對其進行特性實驗。之後將氣凝膠與其他輕質骨材、纖維材加入水泥砂漿中,使用不同的添加配方,觀察其密度、親疏水性、隔熱性、吸水率與抗壓強度。研究結果顯示,本研究成功將疏水性氣凝膠改性為親水性氣凝膠,並將疏水性氣凝膠加入水泥砂漿中。在氣凝膠水泥砂漿的部分,氣凝膠的添加量越多,會使氣凝膠水泥砂漿密度降低並且提升隔熱效果,但抗壓強度也隨著氣凝膠的增加而下降。與灰水泥相比,使用白水泥能提升強度,但隔熱性較差。使用粒徑較小的骨材,能提升抗壓強度,然而隔熱性會下降。添加可再分散乳膠粉1%至2%,可以提升抗壓強度,但隔熱性能依然下降。本研究表明,在水泥砂漿中添加氣凝膠能增加隔熱性能,但同時會降低抗壓強度。最後參考歐盟標準EN 998-1,本研究做出的氣凝膠水泥砂漿均符合輕質與保溫砂漿分類中,對於熱傳導係數與抗壓強度的要求。
英文摘要 With the total world energy consumption increasing year by year, the problems associate climate change continue to increase globally. Building energy saving has become an important issue. Aerogel is a superb thermal insulation material due to the unique properties of aerogel. To achieve the purpose of building energy saving, this study intends to use aerogel into construct materials and do some relation experiments. In this study, the experiments were divided into two parts: preparation of aerogel and adding aerogel to cement mortar. First, using methyltrimethoxysilane (MTMS) as a silica precursor to prepare aerogel through sol-gel method and ambient pressure drying, and the characteristics of aerogel were tested. Then, the different proportions of aerogels, lightweight aggregates and fibers were added to cement mortar. Their density, hydrophilic and hydrophobic, thermal insulation, water absorption and compressive strength were observed. The results showed that hydrophobic aerogel was successfully modified into hydrophilic aerogel, and the hydrophobic aerogel was added into cement mortar. Adding aerogel into cement mortar could improve thermal insulation performance. Nevertheless, it was also reduce compressive strength. Finally, all the mortar made in this study meet the requirements of EN 998-1 standard for thermal conductivity and compressive strength of lightweight and thermal insulation mortar.
