A PROCESS FOR THE PRODUCTION OF REACTIVE BLAST FURNACE SLAG

摘要

The invention particularly relates to a process for increasing the reactivity of ground granulated blast furnace slag using surface activation through short mechanical activation time (10-60 min) and it starts to hydrate in short time (48 h or less) when mixed with water without any chemical additive and completely hydrates in maximum 28 days forming cementitious product. The products produced by the process of present invention may be of different particle sizes and shapes, different specific surface areas, different surface charge (Zeta potential) and different reactivity. The reactive blast furnace slag shall be useful in Portland Slag Cement (PSC), Geopolymer, immobilisation and stabilisation of toxic wastes and newer nano-composite materials.
