本研究將還原碴與水淬爐石粉摻配作為鹼活化膠結材料，並利用氫氧化鈉溶液及矽酸鈉溶液(水玻璃)激發爐碴膠結活性，一方面探討鹼活化爐石粉膠結材料在不同含鹼當量、鹼模數比及水膠比下，對其新拌及硬固性質之影響，另一方面則利用不同比例之還原碴取代水淬爐石粉降低鹼活化膠結材料之成本，探討鹼活化混合爐碴之成本效益，以利於鹼活化技術實際應用與推廣。
試驗結果顯示：(1)含鹼當量高於3%會使凝結時間縮短，提高鹼模數比則可增加漿體之流動性；(2)鹼活化水淬爐石砂漿於含鹼當量4%及鹼模數比1.00時，抗壓強度可優於水泥砂漿之抗壓強度；而提高鹼活化劑濃度對砂漿之抗壓強度發展愈好；(3)還原碴取代水淬爐石粉20%、含鹼當量4%，鹼模數比1.00、水膠比0.5時，抗壓強度高於對照組，但取代量愈高則強度相對下降；(4)降低水膠比至0.4時，還原碴取代量35%之抗壓強度則可達到對照組之水準；(5)經由成本效益分析得知，降低水膠比或是摻配適量還原碴，將可增加鹼活化爐碴之適用性範圍，作為替代水泥之膠結材料。

This study used the mixture of EAF ladle slag and blast furnace slag (BFS) as bonding materials for concrete. Sodium hydroxide and sodium silicate were used as alkali activator to activate the blended powder of slags. First, experimental works considering different dosages of activators, moduli silicate, and water-cement ratio were conducted to investigate the effects of various combinations of parameters on the fresh and hardened properties of alkali activated paste. Then, to reduce the cost of the bonding materials, similar experimental works were conducted on blended furnace slags and the engineering performance was evaluated in detail. Finally, an assessment on the cost benefit of alkali activated blended furnace slags was presented.
Experimental results show that: (1) For the fresh properties, the initial and finial setting times of alkali activated slag paste reduce as dosages of activator increase, and increase in moduli silicate improves the flowability of the activated paste. (2) At alkali dosages of 4% or higher, alkali-activated slag as the binder of concrete shows higher compressive strength than Portland cement. (3) When the replacement ratio of BFS by ladle slag was at 20%, the blended slag can be used as binder for producing mortar with favorable 28-day compressive strength. (4) The replacement level by ladle slag in the blended slag can be increased to 35%, as the water-cement ratio is reduced to 0.4, and still exhibits beneficial properties. (5) The results of cost benefit analysis indicated that reducing the water-cement ratio or using appropriate amounts of ladle slag could increase the application of alkali activated furnace. On the other hand, it can replace cement as bonding material.
