Abstract

A series of glasses in the system CaO-Al2O3-SiO2 was synthetized and studied with respect to their hydraulic reactivity. Generally, the initial reactivity is greater but the developed maximum strength is lower in glasses yielding a hydrogarnet phase, as compared to those yielding gehlenite hydrate. Another factor that determines initial reactivity appears to be the cooling rate of the glass melt. After longer hydration times the strength of glass cement pastes starts to decline, apparently due to a recrystallization of the hydrates formed initially.
