To develop material for lunar construction, it is significant to reduce the weight of material that has to be brought in from Earth. Also, transporting about 0.45 kg from the Earth to space costs about $10,000, which means that building a complete module on our satellite in this way would be very expensive.
That’s why space agencies are now planning to use raw materials from the moon’s surface.
Now a new study came out that suggests astronaut’s pee can be used to build some of the first moon bases. Astronaut’s pee could be used as an additive in making concrete for structures to be built on the moon.
Urea is the second most abundant component in the urine. It can break hydrogen bonds, and therefore reduces the viscosities of many aqueous mixtures.0
