Process for the production of geopolymer or geopolymer composite

Process for the production of a geopolymer or geopolymer composite, comprising

• a) mixing of precursor for aluminate and silicate in alkaline solution, to form a sol-gel,
• b) optionally adding of one or more additives to the sol-gel, to form a filled sol-gel,
• c) adding water to the sol-gel or filled sol-gel, to form a diluted sol-gel or diluted filled sol-gel,
• d) mixing of the diluted sol-gel or diluted filled sol-gel, to form geopolymer or geopolymer composite,
• e) obtaining a suspension of geopolymer or of geopolymer composite,
• f) optional reduction of the content of alkali metal cation within the structure of the geopolymer or geopolymer composite, and
• g) obtaining the geopolymer or geopolymer composite,
• wherein step e) comprises
• e1) decantation,
• or
• e2) adding of an organic phase, emulsifying, and stripping of the organic phase.
