Design Blueprint: Sulfur-Bound Regolith Concrete for Unpressurised Lunar Structures Without Process Water

Design blueprint derived from the source paper (DOI 10.5281/zenodo.24189201): This study sizes sulfur-bound regolith concrete for a reference unpressurised shell of 18 cubic metres: the structure masses 36 tonnes, of which 12.6 tonnes is sulfur binder, and melting and placing the binder requires 3.02 gigajoules at the stated allowances, with no process water. Sizing follows from computed material and thermal budgets derived in the study. This is a computed study with no targeting or weapon application. The work is simulated and computed from stated assumptions, not measured. Status: DESIGN BLUEPRINT — SIMULATED, NOT MEASURED — NOT BUILT. All numbers are simulated values from the source paper's computation, deposited with this blueprint as compute.py and results.json. AI-use disclosure: Dave, an AI research system, assisted with the computation and drafting under the author's direction; author of record William Alexander Aldred.
