本研究提供一廢玻璃之有效再利用方式，使用素玻璃及茶色容器玻璃作為鹼激發膠結材之原料，為求改善其吸水性能，於廢玻璃鹼激發膠結材中加入添加物或改質劑。其中，對吸水性能產生正面影響之添加物及改質劑，皆造成膠結材之強度下降，鈣含量高之添加物則可有效增加膠結材強度，但吸水性能卻相對降低。當飛灰作為添加物時，其受鹼侵蝕時間越短者，越能有效保有吸水介質之特性，若採用偏高嶺土作為添加物時，則需經適量之鹼侵蝕後方能增加其吸水性能。本研究發現添加物取代之最佳配比，乃是以偏高嶺土取代25%素玻璃，於常溫拌合之素玻璃鹼激發膠結材，其抗壓強度可達26.45MPa，且飽和吸水量為自身重量之17%。
此外，本研究結果顯示，改質劑於鹼性環境中無法有效發揮吸水性能，將PEG200添加於無鹼激發茶色玻璃膠結材中，可明顯改善其吸水性能，但抗壓強度亦大幅降低。

An effective way for the reuse of waste pure glass and container glass as raw materials of alkali-activated binders is proposed here. Different types and various amounts of admixtures or modifiers were added in the production of waste glass alkali-activated binders to enhance their water absorption. From experimental results, it is found that the admixture and modifier which make a positive impact on the water absorption of waste glass alkali-activated binders reduce their compressive strengths. The addition of calcium-rich admixtures increases the compressive strength of waste glass alkali-activated binders but decreases their water absorption. When fly ash is used as a raw material and alkali-activated in a short time, the water absorption of alkali-activated waste glass binders can be enhanced. But, when meta-kaolin is used, the water absorption of waste glass alkali-activated binders can be increased only if they are activated by adequate amount of alkali. The best replacement of pure glass by meta-kaolin for waste glass binders alkali-activated at room temperature is 25%, resulting in a compressive strength of 26.45 MPa and a saturated water-absorption of 17%. In addition, experimental results indicate that the effect of modifiers on the water absorption of waste glass alkali-activated binders is insignificant. However, the water absorption of waste glass binders activated without alkalis can be improved significantly when the modifier PEG200 is used.
