    • 越南為全球重要的農業生產國之一，稻米產量長期位居世界前列，因此每年產生大量稻草、稻殼等農業副產物。然而，目前多數稻草仍以露天燃燒方式處理，不僅造成資源浪費，也對空氣品質及生態環境帶來負面影響。另一方面，傳統波特蘭水泥於生產過程中會排放大量二氧化碳，同時伴隨高能源消耗，已成為全球環境議題的重要來源之一。因此，如何開發兼具低碳排放與資源再利用特性的膠結材料，已逐漸成為土木與建築工程領域的重要研究方向。
    本研究以稻草灰（Rice Straw Ash, RSA）及還原碴（ Blast Furnace Slag）作為主要原料，探討其應用於鹼激發膠凝材料之可行性。研究中首先透過熱處理方式提升稻草灰之活性二氧化矽含量，再利用其製備矽酸鈉溶液，並藉由調整矽鈉比（Si/Na）控制鹼激發溶液之組成。此外，以富含鈣質之高爐水淬爐石粉作為前驅材料，以促進鹼激發反應並形成具膠結能力之水化產物。
    為評估材料性能，本研究進一步分析不同配比試體之工作性、凝結行為及抗壓強度發展，並比較不同養護齡期下之力學表現。試驗結果顯示，以稻草灰製備之矽酸鈉溶液搭配高爐水淬爐石粉所形成之鹼激發膠凝材料，可有效提升材料性能，同時兼具降低碳排放與資源循環利用之優勢，顯示其具備取代部分傳統水泥材料之潛力，未來於永續建築材料及綠色工程領域具有良好的應用前景。

    Vietnam is an agricultural country with one of the world's largest rice production volumes, resulting in significant amounts of agricultural by-products such as rice straw and husks. However, the handling of rice straw is not yet systematic and ecological, with a large amount still being burned and regarded as solid waste, causing severe environmental impacts. In addition, the traditional Portland cement industry is considered a significant source of greenhouse gas emissions and energy consumption, significantly affecting the environmental ecology. Therefore, research on developing environmentally friendly alternative binders is an urgent task in construction engineering.
    This study focuses on the fabrication process and properties of alkali-activated binders using rice straw ash (RSA), combined with blast furnace slag from the iron manufacturing industry as raw materials. Rice straw ash was obtained by heat-treating to increase its active silica content and then used in the process of making an activated alkaline solution. Sodium silicate (Na₂SiO₃) solution was synthesized and added to adjust the Si/Na ratio of the activator. At the same time, blast furnace slag was used as a calcium-rich aluminosilicate source to promote the activated alkaline reaction of the resulting binder. The properties of the alkali-activated binder were evaluated through a series of workability, setting time, and compressive strength measurements at different curing ages. The experimental results indicate that alkali-activated binders comprising rice straw ash, blast furnace slag, and a self-synthesized Na₂SiO₃ solution are promising, environmentally friendly alternatives to traditional cement in construction.
