摘　　要：研究了经电收尘及分选的Ⅰ级粉煤灰火山灰反应性 ,探讨了其对水泥基材料强度的影响。结果表明 :相比于Ⅱ级粉煤灰 ,Ⅰ级粉煤灰火山灰活性未必更高 ;The chemical reactivity of grade Ⅰ fly ash and its influence on strength of cement matrix were studied. The results showed that, compared with grade Ⅱ fly ash, grade Ⅰ fly ash was not certainly good in pozzolanic reactivity. And the difference of pozzolanic reactivity of each fly ash does not obviously imfluence the strength of cement mortar.

关 键 词：I级粉煤灰 火山灰活性 水泥砂浆 强度
