Effect of Vacuum Environment on Micro Morphology and Porosity of Lunar Soil Concrete

Abstract: Lunar soil concrete with sulfur system was prepared. The XRD, XRF and SEM datas of lunar soil concrete under atmospheric pressure and vacuum environment after 28 days of curing were compared. The changes of composition and microstructure during solidification of sulfur lunar soil under vacuum and atmospheric pressure were studied. The changes of porosity under atmospheric pressure and vacuum environment were analyzed and compared. Semi quantitative analysis and evaluation are carried out to compare different e… Show more

“…Major aerospace countries have proposed plans for lunar base construction, and lunar regolith has developed from covering soil to various application forms such as lunar regolith blocks, lunar regolith bags, and in-situ hardened sites. The structural materials for lunar surface construction have entered a rapid development period [4][5][6][7] .…”
