There will human traffickings on the way to Mars.

 

Are they telling us something we already wonder? Concrete and blood.

Blood Could Be Key Ingredient For Concrete On Mars

It would take 72 weeks for one astronaut to produce enough bodily fluid to build a small habitat.

It’s conceivable that a future American President will address the nation from the Oval Office on the day NASA successfully lands astronauts on Mars. They will likely praise the blood, sweat and tears it took to travel 140 million miles to the Martian surface. However, those same bodily fluids could be vital building materials for long-term habitation on the Red Planet.

With the vast distances involved, any manned mission to Mars won’t be able to haul substantial solid buildings to another planet. The easiest solution would be to use what’s already there. Researchers from Kharazmi University in Tehran, Iran explored several possible materials. Their findings were published in the journal Acta Astronautica. An excerpt from the report reads:

 

“Although it is a bit strange, blood can be utilized to create strong concrete or bricks for onsite construction on Mars. After the arrival of the first Martian inhabitants and their placement in primary structures, which can include inflatable structures, the combination of tears, blood, and sweat from the inhabitants, along with Martian regolith, can be used to produce a concrete known as AstroCrete. The production process is simple.”

AstroCrete, also known as blood concrete, is a mixture of Martian rocks and bodily fluid. The waterless concrete is considered an ideal solution for the extremely arid environment. Researchers estimated that it would take 72 weeks for a crew member to generate enough fluid to build a habitat. Once more astronauts arrive on Mars, there would be a steady stream of fluid. The base expansion would be self-sustaining. More habitats allow for more people. More people means more fluid.

 

The researchers note that ancient Romans used animal blood to reinforce their mortar. However, AstroCrete has some issues. Living on Mars will be a physical challenge and forcing astronauts to constantly donate blood would hamper progress on all other projects on the Martian surface. Also, the material’s low density would offer lackluster protection against cosmic radiation.

Space programs will find a long-term construction solution for Mars eventually. Considering NASA’s delays in returning to the Moon, the agency has plenty of time to brainstorm ways to build on the Red Planet without literally bleeding it’s astronauts dry.

4.2. AstroCrete or blood concrete

Ancient Romans utilized organic additives, including animal blood, primarily to improve the durability and workability of their mortar [99]. However, it is possible to create high-performance concrete using blood as a primary component. Although it is a bit strange, blood can be utilized to create strong concrete or bricks for onsite construction on Mars [100]. After the arrival of the first Martian inhabitants and their placement in primary structures, which can include inflatable structures, the combination of tears, blood, and sweat from the inhabitants, along with Martian regolith, can be used to produce a concrete known as AstroCrete (Fig. 7a) [101]. The production process is simple. Aggregates (Martian regolith) bind together through contact with human serum albumin (HAS), a protein found in blood plasma. Over a period of 72 weeks, a crew member could generate sufficient HAS to construct a small habitat for another crew member [100]. Also, it is possible to increase compressive strength, improve ductility (better plastic behavior) and decrease the brittle behavior of the AstroCrete by adding carbamide (urea), a compound that can be extracted from sweat, tears and urine [102]. This concrete could be used in 3D printers and would be cured in the atmosphere of Mars (Fig. 7b). The following pros and cons can be listed for construction on Mars using AstroCrete.

AstroCrete is a waterless concrete, making it suitable for the dry environment of Mars.

The compressive strength and Young’s modulus of the AstroCrete (using MGS-1 + HAS + urea) could reach almost 12 MPa and 1 GPa, respectively [103]. This is not suitable for structural design.

Due to its relatively low density, AstroCrete may not be effective as a cosmic ray shield.

AstroCrete requires massive imports from Earth. In other words, one of the main compositions (blood) depends on the astronauts or space travelers that should be imported from Earth.

AstroCrete is a new concrete, and its long-term behavior in harsh Martian environments is not yet well understood.

AstroCrete can be used in 3D printers, enabling remote and automated construction on Mars.

With an increasing number of inhabitants on Mars, there would be a steady supply of blood for producing AstroCrete (steady expansion), facilitating the construction of low-cost Martian bases.

Martian missions are long-term and can have adverse effects on human health, including insomnia, joint pain, and headaches [81]. These health issues could potentially impact the use of blood and blood donation for AstroCrete production. The effects of blood donation on the health of settlers on Mars should also be considered. Additionally, the amount of blood required for constructing a suitable Martian base, as well as the number of inhabitants needed, is questionable and should be studied in the future.
