Scientists have developed concrete made of potato starch, salt, and space dust, which is suitable for constructing buildings on Marsand the Moon.

Strength doubled
Dubbed "StarCrete," the new material exhibited compressive strength of 72 Megapascals (MPa), about twice more than ordinary concrete.
3
Potato-based concrete
The team estimated that about 25 kilograms of dehydrated potatoes were sufficient to produce half a ton of StarCrete, which is enough to make about 213 bricks.

StarCrete strengthenedby salt
Magnesium chloride was found to significantly improve the strength of StarCrete. This common salt is present in Martian soil.
5
Greener concrete potential
StarCrete could have potential implications on Earth as well, serving as a greener alternativeto traditional concrete.
