Abstract:
The construction of the lunar base is a key step for the deep space exploration in the future. Based on a review of literature at home and abroad, the feasibility of developing the geopolymer concrete from the in-situ lunar resources is discussed, together with the possibility of the geopolymer used as the lunar base construction material. It is shown that 90% of the raw material for preparing the geopolymer concrete can be obtained from lunar resources, and the geopolymer can withstand the compound lunar environment. The printability of the geopolymer by the extrusion printing and the powder printing is also discussed, which validates the feasibility of the 3D printed geopolymer. It is shown that the geopolymer concrete can meet the construction requirements and has adequate environmental adaptability under the lunar environment. The use of the geopolymer material for the in-situ construction of the lunar base is conceptually feasible, while further theoretical analyses and experimental assessments are still needed.
