Abstract
A geopolymer cement and a method of producing the same are provided. A geopolymer cement binder may be provided including a geopolymer precursor and magnesium oxide as an alkali activator. The geopolymer cement binder may be mixed with water using high shear mixing.
Claims24
A method of producing geopolymer cement comprising:
- providing a geopolymer cement binder comprising:
- a geopolymer precursor;
- and
- magnesium oxide as an alkali activator;
- and
- mixing the geopolymer cement binder with water including mechanically breaking down one or more of the geopolymer precursor and the magnesium oxide to react and form one or more of hydrotalcite phases and magnesium-silicate-hydrate phases, wherein mixing the geopolymer cement binder with water includes using high shear mixing including one or more of:
- mixing with an overhead mixer having a toothed dispersion blade;
- mixing with a rotor-stator high shear in line mixer;
- and
- mixing with a multi-stage cylinder mixer.
