本研究主要探討下列因素對於無機聚合物其工程性質之影響：(1) 燒高嶺土之煅燒溫度與持溫時間；(2) 矽、鋁離子之析出數量；(3) 矽鈉重量比；(4) 液固比；(5) 高嶺土原礦。
研究結果顯示：(1) 以熱分析與X光繞射分析可判別高嶺土有效之煅燒溫度與持溫時間，煅燒溫度須達到700℃以上並持溫3小時才可完全脫羥基而形成偏高嶺土。(2) 在相同濃度下，添加不同體積的10 N KOH鹼激發劑溶液，液固比為5：1時，鋁離子會較矽離子先達到最高析出莫耳數量。(3) 在不同矽鈉重量比條件下所製成之無機聚合物，當矽鈉重量比為0.4時，其放熱效應大且快速硬固，導致不良之工作度，易產生大量孔洞與熱裂縫，所以其工程性質較差；而當矽鈉重量比為0.7與1時，皆可改變液固比而達到最佳強度，故同時考慮配比中之矽鈉重量比及液固比而達到最佳鍵結比例時，即可獲得最佳工程性質。(4) 在相同配比下，以不同產地的偏高嶺土拌合製成無機聚合物時，其工程性質不盡相同，會依高嶺土的物理及化學性質不同而有所差異，所以不能以水泥水化中之水灰比及水膠比之觀念來套用在無機聚合反應，必須將所有反應材料之基本性質與化學分子式了解後，再依前述觀念設計配比。(5) 無機聚合物漿體擁有優良的抗壓強度及低熱傳導係數，故於防火絕熱與耐高溫等應用條件上皆具有相當的發展與研究空間。

This study explores the influences of the following factors on the engineering properties of geopolymer: (1) sintering temperature and time of kaolin, (2) amounts of silicon and aluminum ions released from kaolin, (3) weight ratio of SiO2 to Na2O (SiO2/Na2O), (4) ratio of liquid volume to solid weight (liquid/solid), and (5) raw materials.
Results are summarized as the following: (1) Effective sintering temperature and time was differentiated by thermal analysis and XRD. The dehyrdoxylation of kaolin did not occur until the heating temperature was maintained at 700 °C for 3 hours. (2) When liquid/solid=5, by adding different volumes of the alkali activation of 10 N KOH solutions, the released aluminum ions reached the maximum amounts earlier than the silicon ions. (3) When SiO2/Na2O=0.4, the geopolymer had large heat release and rapid stiffening, inducing poor workability, pores, and thermal cracks. Its engineering properties were thus bad. However, when SiO2/Na2O=0.7 or 1, compressive strength of the geopolymer was optimized by changing the liquid/solid ratios. Therefore, better engineering properties of the geopolymer can be achieved by adjusting both the SiO2/Na2O and liquid/solid in a mix design to get a better bond. (4) Engineering properties of the geopolymer varied with the physical and chemical properties of the kaolin of different origins. Therefore, the concepts of water-cement ratio or water-cementitious materials ratio are not applicable on the geopolymerization. It is suggested that the materials properties of the reactants should be determined and the chemical reactions during the geopolymerization should be clarified prior to the mix design. (5) Geopolymer had high compressive strength and low thermal conductivity, suggesting its potential use on fire-resistance and thermal insulation.
