TL;DR: Sulfur Concrete Casting is a main entry in the 外星矿物知识引擎 database.
Mixing molten sulfur (130-140°C) with regolith aggregate to produce structural concrete without water
Input Material
Sulfur (from troilite) + regolith aggregate
Output
Structural concrete elements
Efficiency
Rapid setting; compressive strength comparable to Portland cement
Space Viability
Excellent - no water needed; sulfur available from regolith; low temperature process
