本文探讨了水泥-粉煤灰体系中水泥熟料水化度和粉煤灰火山灰反应度的测定方法。在此基础上，研究了粉煤灰的活性作用。研究结果表明，粉煤灰的活性作用主要表现在两个方面：（1）粉煤灰具有较强的火山灰活性，能与Ca（OH）2发生反应;（2）粉煤灰能促进水泥的水化。当粉煤灰掺量较少时，其火山灰活性能较好地发挥，但对水泥水化的促进作用较弱。粉煤灰掺量越大，其火山灰活性越小，但对水泥水化的促进作用越强。(C)2004年由Elsevier Ltd.出版。
This paper examines the method for determining the hydration degree of cement clinker and the pozzolanic reaction degree of fly ash in the system of cement and fly ash. In the base, the active effect of fly ash is studied. The studied results show that the active effect includes two aspects: (1) Fly ash has stronger pozzolanic activity and can react with Ca(OH)(2), and (2) it can promote the hydration of cement. When the content of fly ash is less, its pozzolanic activity can exert well, but its promoting role to the hydration of cement is weaker. When the content of fly ash is more, it is less than its pozzolanic activity can be used, but its promoting role to the hydration of cement is stronger. (C) 2004 Published by Elsevier Ltd.
