In its most common #terrestrial 🌍 formulation, #concrete is held together with a binder made from #cement powder and water. But cement is made mostly from limestone—a mineral not present on #Mars 🔴 —and Martian water 💧 is rare and precious. An alternative is concrete bound together by #sulfur, of which #Mars has plenty. Two samples' fracture toughnesses 💪 were even higher than that of cement-based terrestrial concrete https://pubs.aip.org/physicstoday/Online/41866/Martian-concrete-could-be-tough-stuff

🏗️ #Lunar and #Martian #StarCrete achieved compressive strengths of 91.7 and 72.0 MPa, respectively, which is well within the domain of high-strength concrete (>42 MPa). Made from 🥔 starch + regolith. https://www.degruyter.com/document/doi/10.1515/eng-2022-0390/html
