Scientists test method to produce low-grade concrete from Martian sand
Researchers developed a method using yeast and gelatin to make concrete on Mars, CNET reports.
The short version
- A study published in Chem Circularity outlines a technique to convert Martian sand into low-grade concrete using gelatin, yeast, and local environmental conditions.[CNET]
- Senior author Jishen Qiu said the material achieves 10 to 12 megapascals of strength, comparable to low-grade terrestrial concrete.[CNET]
- The research team validated the process by 3D printing two small cork-sized structures within a simulated Martian environment.[CNET]
Key facts
- A study in Chem Circularity reports that Martian sand can be converted into low-grade concrete using gelatin, yeast, and Martian environmental factors.[CNET]
- The resulting material measures 10 to 12 megapascals, placing it on par with low-grade concrete on Earth, according to senior author Jishen Qiu.[CNET]
- Researchers demonstrated the approach by 3D printing two small beehive-shaped models roughly the size of a wine cork in a simulated Martian setting.[CNET]
What remains uncertain
- Whether the technique can successfully scale from cork-sized test prints to full-scale habitable structures on Mars remains untested.[CNET]
