Summary

This paper presents the formulation and evaluation of GCD-1 lunar regolith simulant, which mimics the Apollo 14 lunar soil. The simulant was used to prepare a geopolymer with solid sodium silicate activator and water. The geopolymer's strength was tested under simulated lunar equatorial temperature conditions. Microstructural analysis revealed the role of hydrated sodium aluminosilicate gels in enhancing compressive strength. The paper presents the development of a novel geopolymer material using lunar regolith simulant and alkali activators. The material is designed for potential use in lunar base construction. The study investigates the mechanical properties, microstructure, and thermal stability of the geopolymer. The results indicate that the geopolymer exhibits good compressive strength and thermal resistance, making it a promising candidate for lunar construction applications.
