摘　　要：研究了三峡工程用Ⅰ级粉煤灰效应优势及其对水泥砂浆强度的贡献。结果表明 :相比于Ⅱ级粉煤灰 ,Ⅰ级粉煤灰的火山灰活性未必更高 ,但Ⅰ级粉煤灰颗粒形态效应上的优势导致了其对水泥砂浆强度产生更明显的影响。This paper studies the effective superiority of Ⅰ grade fly ash and effects on the strength of cement sand mortar in Sanxia engineering.The results show that compared with Ⅱ grade fly ash,Ⅰ grade fly ash is not certainly good in chemical reactivity,but its advantage in shape effect is obvious to the strength of cement sand mortar.

关 键 词：粉煤灰 火山灰活性 形态效应 水泥砂浆 强度 三峡工程
