Summary

This study developed a high-fidelity lunar regolith simulant (GCD-2) based on Chang'e-6 samples. A lunar regolith geopolymer (LRG) was synthesized using GCD-2 and sodium silicate. Dynamic mechanical properties were evaluated using SHPB. Ca/Si and Al/Si ratios influenced compressive strength and energy absorption. Optimal thermal curing and mixing time were identified for lunar surface applications. The provided text is a mix of metadata, content links, and references related to a scientific paper. It includes information about the paper's title, authors, publication date, license type (CC BY-NC), and links to the full text and figures. The paper appears to be about the properties of a lunar regolith simulant and its potential applications in space exploration. 1215X/gr5/DOWNSAMPLED/image/jpeg/25460732173f4c5ec8399c994b43cc2c/gr5.jpg gr5 gr5.jpg jpg 18609 266 339 IMAGE-DOWNSAMPLED https://s3-eu-west-1.amazonaws.com/prod-ucs-content-store-eu-west/content/pii:S221450952501215X/gr4/DOWNSAMPLED/image/jpeg/dc86b2c927c702cc13db51a05e1c71c8/gr4.jpg gr4 gr4.jpg jpg 95415 572 715 IMAGE-DOWNSAMPLED https://s3-eu-west-1.amazonaws.com/prod-ucs-content-store-eu-west/content/pii:S221450952501215X
