Printability and hardening performance of three-dimensionally-printed geopolymer based on lunar regolith

Frontiers of Structural and Civil Engineering doi: 10.1007/s11709-023-0003-0

Abstract: This study aims to improve the printability of a geopolymer based on a BH-1 lunar regolith simulant,Rheological parameters were used to represent printability with different water-to-binder ratios, printingshow that heating the printed filaments with a water-to-binder ratio of 0.32 at 80 °C can adjust the printabilityThe printability of the BH-1 geopolymer can also be improved by adding 0.3% Attagel-50 and 0.5% polypropylene
