Geopolymer concrete can be prepared with approximately 70%–80% aggregates and 20%–30% geopolymer binder [47]. In fact, if lunar (or Martian) regolith is found to exhibit geopolymerization, then the raw materials needed (up to 90% of the total mass) to produce geopolymer concrete could be collected from in situ materials.
