摘要
研究了高钙粉煤灰的本征性质与其火山灰活性之间的关系，以及高钙粉煤灰水泥的膨胀特性等。结果表明，高钙粉煤灰具有水化活性高、减水效果好、早期强度发展快等优点。采取适当的技术措施，可使之成为一种高效的水泥混合村或混凝土掺合科。
This paper introduces the intrinsic characteristics of high calcium fly ash and its relation with pozsolanicity and the expansion Property of fly ash cement thus made. The experimental results reveal that high calcium fly ash has very good activating action onhydraion;good reducing effect on water - cement ratio and rapid development of eary strength of the cement. It is a valuable materi-al for using as cement aboture or concrete additive if proper technical measares are taken.
