鹼質粒料反應為一長期的混凝土劣化問題，由過去的研究結果發現，台灣東部地區所產砂石的鹼反應潛能相當的高，用做混凝土粒料將有相當大的機會發生鹼質粒料反應。因此本研究針對蘇澳、花蓮地區中各主要砂石供應河川所產砂石進行鹼質粒料反應潛能試驗並進行評估，以供未來施工時粒料選擇的參考；另外，針對鹼質粒料反應的抑制策略研究上，本研究以添加爐石作為抑制策略，以期找出最佳的添加方式。 The Alkali-aggregate reaction (AAR) is a kind of concrete deleterious problem. From past investigations, it was found that aggregates quarried from the east area of Taiwan could be highly reactive. AAR will occur when using these aggregates for concrete. For these reasons, several tests which can judge the potential of aggregates will be carried out by using the rocks from the main aggregate-producing rivers between Suao and Hualien as aggregates to calculate the potential of aggregates. Results gained from these tests would be an important reference of aggregate choosing in practice. Besides, in the investigations of AAR mitigation counterplot, our research use slag powder as mitigation admixture and try to find best mixture. 研究期間：9408 ~ 9509
