Preparation of a Lunar Regolith Simulant for In-Situ Construction Research: TC-1C

The core objective of human lunar exploration has shifted from “understanding the moon” to a dual focus on “understanding and utilization.” In order to meet the requirements for lunar in-situ construction research, a specific method for the preparation and evaluation of simulated lunar regolith was proposed. Using the Chang'e 5 lunar samples as a reference, the study developed a simulated lunar regolith, TC-1C (Tsinghua-China Building Materials Academy-type1 for Construction), and assessed its similarity in four key parameters: phase composition, particle size distribution, particle morphology, and density. The results indicated that the similarity of TC-1C to the actual Chang'e 5 lunar regolith exceeded 0.94.
