%X Water-quenched samples were prepared by re-melting blast furnace slag and then quenching it at different temperatures. The effects of forming process on the relationship between structure and cementitious reactivity of quenched slag were studied by XRD, DTA, TEM, SEM and EDX techniques in combination with mechanical property and alkali leaching tests. The results show that phase separation phenomena of different extents exist in samples. The samples with phase separation in completely vitreous structure possess better cementitious reactivity. Such vitreous structure consists of both Ca-rich and Si-rich phases, Rapid dissolving of Ca-rich phase and slow dissolving of Si-rich phase contribute to the cementitious reactivity of quenched slag.
