Analysis of Lunar-Habitat Structure Using Waterless Concrete and Tension Glass Fibers

Abstract

The studies reported in this paper were undertaken to evaluate the maximum use of lunar in situ resources for surface construction, such as a habitat structure for a permanent manned lunar base. This type of activity is well into the future, but there are possible near-term applications that could utilize in situ resources for protection from radiation of surface power reactors, solar flares, and micrometeorite damage. “Waterless” concrete made of sulfur, a by-product material of oxygen and carbon extractions, is a viable alternative to hydraulic cement. Sulfur–lunar regolith concrete is an ideal material for building structures on the moon. Its availability, high strength, and durability properties make it a very attractive candidate for the development of the first lunar-construction activities. Regolith-derived glass rebar and fiber can also be used with “concrete” made with in situ regolith. Development of such habitats pose tremendous challenges that can be met by the combination of innovative design with cutting-edge technologies that are appropriate for planetary surface habitats with multiple applications for Earth and beyond.
