現有輕質泡沫材料大多使用卜特蘭水泥作為主要膠結材，然而，水泥生產過程高耗能且高二氧化碳排放量，對環境生態造成嚴重衝擊，鹼激發膠結材之製造過程屬低耗能與低汙染，根據鹼激發反應機制，凡富含鋁矽酸鹽之礦物材料皆可作為原料，經研磨後之廢容器玻璃粉末，即富含二氧化矽符合鹼激發膠結材原料之需求，可取代水泥製成泡沫材料。由於容器玻璃廢棄後大多採掩埋方式處理，除大量佔據埋地空間，同時造成環境生態汙染，此外近年容器玻璃回收比例雖有所提升，但缺乏材料資源化再利用管道，若能將其作為鹼激發膠結材原料，開發一具高經濟性之新型輕質泡沫材，將可達成減用卜特蘭水泥與有效消耗廢容器玻璃之雙重目的。本研究以經研磨之廢容器玻璃粉為原料，使用僅含氫氧化鈉之鹼活化液，依不同設計相對密度，於拌合時添加適量預成形泡沫於鹼激發玻璃膠結材中，選用適宜之養護製程方式，以期所製成輕質泡沫材料試體具有良好抗壓強度，同時，為降低製造成本將減低鹼活化液所需用量，並縮短製造養護時程，最終，藉由試驗結果相互比較，以獲得製作鹼激發玻璃泡沫材料之最佳配比參數與養護條件，評估所製成鹼激發玻璃泡沫材料之物理與力學性質，檢核其是否符合實務應用所需之標準，以及取代卜特蘭水泥泡沫材料之可行性。

Portland cement slurry is typically used as a binder in the production of lightweight foams. However, the manufacturing process of Portland cement is high energy consumption and results in the emission of carbon dioxide, causing a serious impact on the earth environment and ecology. The manufacturing process of alkali-activated inorganic binders, made from materials with rich aluminosilicate, is less energy consumption and more environmentally friendly. Waste container glasses are mostly disposed of by burial and thus not only occupy a lot of landfill space but also cause environmental and ecological pollution. Hence, a novel construction material made from waste container glasses should be developed to reduce their pollution and to replace Portland cement as binder in concrete. Waste container glasses powders composed of rich silica can be used as raw materials to produce alkali-activated binders and foams. In the study, waste container glass powders were mixed with the alkaline activator containing only sodium hydroxide. As a result, the cost of the resulting alkali-activated glass binders and foams is lower and can be utilized to replace cementitious ones. Different amounts of pre-formed air bubbles were weighed and then mixed completely with alkali-activated glass binders to produce slurry foams with various relative densities. The slurry foams were then cured in a suitable maintenance process to shorten their curing duration and to reach good compressive strength. The compressive strengths of alkali-activated glass foams were tested mechanically and then compared to determine the optimal proportions of constituent materials and curing process conditions. Also, the physical and mechanical properties of the alkali-activated glass foams were evaluated to check if they satisfy the required standards for practical applications and the replacement of Portland cement foams is feasible.
