“…Although cost is not a sensitive factor, the limitation on weight and size leads to unique challenges, e.g., the low binder content of composite lunar "cement" (CLC). A CLC is formed by bonding lunar soil grains with a small amount of polymer binder (Casanova and Aulesa 2000). It can be used for future construction and expansion of lunar bases and outposts, on-site fabrication of large-scale research and space facilities, and so on.…”

In order to minimize the binder content in composite lunar "cement," this paper uses JSC-1A lunar soil simulant and unsaturated polyester resin (UPR) to produce low-binder-content composite. Important system parameters such as compression pressure, compression duration, vibration, loading rate, loading number, and initial grain size distribution are analyzed. The most critical control variable is the compression pressure: at ∼350 MPa, the binder content is reduced to 6.5-8.7% by weight and the flexural strength is approximately 30-40 MPa. This research is important for in situ resource utilization for future lunar base construction and expansion. ASCE 06017013-1 J. Mater. Civ. Eng. J. Mater. Civ.
