3. Slag/rock-based geopolymer cement
Raw materials :
MK-750 metakaolin or calcined clay ;
blast furnace slag ;
volcanic tuffs (calcined or uncalcined) ;
mine tailings ;
alkali silicate (user-friendly ).
Geopolymer structure :
Si:Al = 3; crude formulation (K,Na,Ca)-poly(sialate-disiloxo); actually a solid solution comprising two geopolymers:
Si:Al = 1, Ca-poly(disialate), hydrated anorthite type;
-
Si:Al = 3-5, (K,Na)-poly(sialate-multisiloxo)
with calcium disilicate hydrate CaO.2SiO 2 .2H 2 ...
