摘要

目前在結構修復補強中，經常使用環氧樹脂作為粘接或修補材料。環氧樹脂屬於有機質材料，其粘接補強之效果雖尚佳，但不耐高溫之性質，所造成之後果就可能十分嚴重。前期研究已顯示混凝土試體所包覆之CFRP若以環氧樹脂作為黏接劑，在溫度達250℃~300℃時將失去圍束效果。近年來國外正逐步開發一種「矽鋁無機聚合物」材料，應用於包括混凝土及防火隔熱等方面，而國內除了材料科學領域稍有涉及之外，在其他應用方面之發展尚有限。本研究則嘗試開發相關之粘接材料，定名為「無機聚合樹脂」，以一系列的實驗研究探討其替代環氧樹脂的可行性。首先以強度、粘接性、耐高溫性、及低施工敏感性之角度，開發調製聚合樹脂之配比。其次則進行包覆CFRP混凝土試體之強度及高溫性能實驗研究。結果顯示無機聚合樹脂對於CFRP之粘接性能雖未及環氧樹脂，但確可發揮圍束補強效果。而其在耐高溫方面之性能則遠超過環氧樹脂，初步顯示在溫度達到800℃時仍未失去圍束效果，充分展現了潛能。此外，由於無機聚合樹脂之配方可包含飛灰或玻璃粉等環保材料，使其在經濟性方面較其他傳統粘接材料更具有競爭力。

So far, epoxy has been massively used during structure retrofit. Epoxy is an organic material, the properties of poor temperature would cause serious problems. The result of preceding research revealed that for concrete cylinders covered by CFRP using epoxy as bonding material, and lost completely when the temperature reached 250~300℃. Presently, a new material, namely geopolymer is under development worldwide for making concrete and isolation products. In Taiwan, such materials have only been studied in material science. The proposed research was tried to develop boned material, called 「geopolymer」, aimed at this direction doing experimental study to replace epoxy. First, the geopolymer will be developed in views of strength, durability, bonding property, error sensitivity, as well as cost. Secondly, it is using geopolymer applied between concrete cylinder, CFRP jacket and the high temperature study. The result was poor than epoxy on boned properties, but it is better than epoxy on the resisting high temperature properties, and the result revealed that geopolymer is not abolish on 800℃. Besides, the formula of geopolymer can comprise green materials like fly ash or glass dust, and it will become better than conventional materials in economic.
