Summary

This paper investigates the rheological properties and 3D printing performance of TJ-1 simulated lunar soil-based polymers. The study explores the effects of solid-liquid ratio, Ca(OH)2, and HPMC on the material's workability. The modified Bingham model is found to accurately describe the rheological behavior. The yield stress and plastic viscosity of the polymer with 0.15% HPMC are 3.577 Pa and 0.733 Pa s, respectively. The 28-day compressive and flexural strengths are 19.5 MPa and 6.9 MPa, meeting the standards for ordinary sintered bricks. The paper presents an experimental study on the development of extraterrestrial construction materials using lunar regolith simulants. The study focuses on the fabrication of lunar regolith-based concrete and its mechanical properties under different curing conditions. The results indicate that the addition of certain binders and curing conditions significantly improves the compressive strength and durability of the material. The study also discusses the potential applications of this material in future lunar construction projects.
