“…This is an attractive alternative to conventional concrete as water, a precious resource, is not required. Reducing troilite to elemental sulfur and using sulfur concrete on the moon has been previously discussed (Casanova, 1997;Gracia and Casanova, 1998;Leonard and Johnson, 1988;Roqueta and Casanova, 2000;Toutanji et al;Vaniman et al, 1992). For our purposes it is assumed that elemental sulfur is available on the lunar surface and sulfur concrete products such as bricks can be made.…”

Melting sulfur and mixing it with an aggregate to form ''concrete'' is commercially well established and constitutes a material that is particularly well-suited for use in corrosive environments. Discovery of the mineral troilite (FeS) on the moon poses the question of extracting the sulfur for use as a lunar construction material. This would be an attractive alternative to conventional concrete as it does not require water. However, the viability of sulfur concrete in a lunar environment, which is characterized by lack of an atmosphere and extreme temperatures, is not well understood. Here it is assumed that the lunar ore can be mined, refined, and the raw sulfur melded with appropriate lunar regolith to form, for example, bricks. This study evaluates pure sulfur and two sets of small sulfur concrete samples that have been prepared using JSC-1 lunar stimulant and SiO 2 powder as aggregate additions. Each set was subjected to extended periods in a vacuum environment to evaluate sublimation issues. Results from these experiments are presented and discussed within the context of the lunar environment. Published by Elsevier Ltd on behalf of COSPAR.
