Abstract
The effect of amorphous Al(OH)3 on the hydration of tricalcium aluminate was investigated in pastes and in suspensions. In suspensions, it was found that amorphous Al(OH)3 started to dissolve almost immediately, and a stage was passed in which most of the anions present in the aq. phase were polymeric aluminate units. Paste hydration results could be understood by assuming that highly sol. amorphous Al(OH)3 dissolved and, by so doing, adjusted the concns. in the aq. phase so as to cause pptn. of some less sol. form of Al(OH)3, thereby retarding hydration.
