摘　　要：研究粉煤灰的形貌、微观结构、形成机理及水化界面特性。水化后期,粉煤灰颗粒表面层已完全与水泥水化产物发生二次反应,填充水泥石的孔隙空洞,使孔结构高度细化,强度逐渐提高。The modality, micro - structure, formation mechanism and the hydration interface features of fly ash are investigated. In the later stage of hydration, the surface of the fly ash particles have a completely secondary reaction with cement hydration products, then the hydration products fill the pores in the cementing matrix, finally the pore structure get fined and intensified.
