  • The Influence of Ground Fly Ash on Cement Hydration and

     · In this study the ground fly ash is made of ordinary grade I fly ash by grinding. Compared with grade I fly ash the influence of ground fly ash on cement hydration and mechanical property of mortar was investigated. The results show that ground fly ash can improve the hydration of cement at all the ages compared with grade I fly ash and not only does its pozzolanic reaction start earlier
