2. Slag-based geopolymer cement/MK-750

Raw materials :

• MK-750 metakaolin (see [N 3 300] for chemical definitions);

• blast-furnace slag, quenched and ground to a grain size similar to that used for Portland clinker;

• alkali silicate with molar ratio SiO ₂ :M ₂ O > 1.45.

Geopolymer structure :

Si:Al = 2; crude formulation (K,Na,Ca)-poly(sialate-siloxo); actually a solid...
