To Build on Mars . . .

Save your pee. And draw some blood. Not quite as neat and simple as bees and wasps, who build using substances from their bodies, but vaguely similar.

"Scientists Develop 'AstroCrete' Concrete for Affordable Housing on Mars" | Greek Reporter

Quote
The University of Manchester has developed a “cosmic concrete” called AstroCrete to make the colonization of Mars cost effective. The material is more durable than typical concrete and can function longer in Mars’ challenging environment.

The material is composed of an unlikely and slightly unsavory combination of sweat, tears, urine and a protein from human blood. The protein works to bind the other ingredients together so that the tough material can adequately hold together on Mars’ soil.

AstroCrete has an overall strength of up to 25 Megapascals. The new material’s strength was multiplied by 300 when researchers mixed urea (contained in urine, sweat, and tears) into its recipe. Some of the AstroCrete tested was shown to be stronger than normal concrete.

Dr. Aled Roberts, a research fellow at The University of Manchester who helped create the material, said that “The new technique holds considerable advantages over many other proposed construction techniques on the moon and Mars.”

“Scientists have been trying to develop viable technologies to produce concrete-like materials on the surface of Mars, but we never stopped to think that the answer might be inside us all along.”

“It is exciting that a major challenge of the space age may have found its solution based on inspirations from medieval technology.”
