This paper describes the synthesis and characterization of a geopolymer from a new lunar regolith simulant (GVS) based on natural volcanic scoria. The simulant was compared with Apollo lunar soil samples and commercial simulants. The geopolymer's mechanical properties and microstructure were analyzed using various techniques, including XRF, XRD, FTIR, SEM-EDS, and NMR. The study highlights the potential of GVS-based geopolymer for lunar colony construction. The paper discusses the synthesis and characterization of a geopolymer-based lunar regolith simulant derived from natural volcanic scoria. The study involves material preparation, mechanical property analysis, and microscopic testing. Key methods include XRD, FTIR, 29 Si MAS-NMR, 27 Al MAS-NMR, and SEM-EDS for mineral phase, chemical bond, and microstructural analysis.
