Preferential Sorption of Minerals on Calcium Hydroxide of Hydration Productions of Cement

Abstract:

Forming progress of hydration productions CH are analyzed in this paper by ways of SEMs of hardened cement paste with or without ground granulated blast furnace slag and high-calcium fly ash. It presents that minerals with latently hydraulic or pozzolanic are apt to absorb CH crystal to grow around it. There are clearly hydraulic reactions in the partial surface of mineral grains connecting with CH crystal and there is little hydration in the part without CH surrounding. It indicates that increasing the absorbability of mineral grain for CH crystal is probably a useful method to advance reactivity of minerals with low activity.
