| Abstract Scope |
This study investigates the carbonation behavior and binding mechanisms of regolith–magnesium oxide (MgO) composites as a low-energy construction material for Martian infrastructure. The proposed approach utilizes the chemical reactivity of MgO with CO₂ to form magnesium carbonate phases that bind regolith particles into consolidated composites without conventional cementitious binders. Particular emphasis is placed on carbonation-induced phase formation and its role in enhancing the mechanical performance of the composites. Preliminary results demonstrate that the carbonated regolith–MgO composites achieve compressive strengths exceeding those of conventional concrete, highlighting their potential for load-bearing applications in extraterrestrial environments. The influence of Martian thermal cycling and freezing conditions on carbonation kinetics, phase evolution, and microstructural development is also investigated to evaluate material performance under realistic surface conditions. Overall, the results demonstrate the feasibility of manufacturing high-strength, low-energy construction materials from in-situ Martian resources, reducing reliance on Earth-supplied materials for future planetary infrastructure. |
