Overview

Experimental analysis demonstrates mechanical properties of lunar regolith geopolymer for structural use, indicating promising applications for lunar construction.

Key Points

  • This research aims to evaluate the stress-strain behavior and mechanical properties of lunar regolith-based geopolymer.
  • Prepared forty-eight cylindrical specimens of CQU-1 lunar regolith simulant geopolymer.
  • Tested under axial compression with variations in curing temperature and time.
  • Analyzed the effects of water-binder ratios on performance.
  • Achieved maximum compressive strength of 33.89 MPa under optimal conditions.
  • Increased curing temperatures and times improved stiffness while reducing strains.
  • Higher water-binder ratios decreased peak stress and increased ultimate strains.
