Cooling history of a wet-granulated blast furnace slag ...

2018-11-1  Cooling history of a wet-granulated blast furnace slag (GBS) of >99% glass fraction is studied. • Fictive temperature of GBS is approx. 160 K higher than T g under standard cooling conditions.. Glass structure is frozen-in at a viscosity of 10 5.9 Pa s.. Cooling rate of the quench is approx. 2.6 × 10 5 K s −1.. GBS is assigned to the class of hyperquenched glasses.
