As the lunar exploration mission evolves from exploration to construction and utilization, in situ lunar construction becomes an imperative requirement. The key is regolith solidification and formation, aiming to maximize local resource utilization while minimizing transportation and maintenance costs.

Nearly 20 techniques have been employed for preparing regolith-based construction materials, each with distinct requirements and capabilities. Professor Feng from Tsinghua University has conducted a comprehensive review, precise classification, and quantitative evaluation of regolith solidification and formation techniques, shedding light on key challenges and future development directions.
