An agenda was created to build bases on the nearest stellar neighbor to assist in space expedition and to use as a possible starting point to mars, by both China National Space Administration and Nasa. The recent expense of taking just 0.45kg to space would be perhaps $10,000, making the expectation of having any kind of permanent Moonbase is an extortionate proposition. The scientists have been trying to cut this cost off by reusing or repurposing the space-bound materials as much as it is feasible.
It is brought into being, by the team of researchers from Netherlands, Spain, Norway, and Italy with collaboration with the European Space Agency that the UREA in the urine can be used as a plasticizer in the construction of concrete structures. Plasticizers are used as an additive mixture that can be added to the concrete to make the initial mixture soft and make it more flexible before it hardens. The material to make concrete can be procured from the rock matter found in the moon itself. Professor Ramon Pamies said, "To make the geopolymer concrete that will be used on the moon, the concept is to use what is already there: regolith (loose material from the moon's surface) and water from the ice-present in some areas" at the Polytechnic University of Cartagena.
The two main components of the human body fluid that can be used to break hydrogen bonds and, therefore, reduce the viscosity of many aqueous mixtures are water and urea. With this knowledge, we can conclude that a waste product of humans can also be used in construction. Using a 3D printer the team manufactured 'mud' cylinders which are similar to a material developed by moon regolith, together with urea and various plasticizers, and compared the results. The sample containing urea could support heavyweights and had a lot of stability. Experimenting with the temperatures similar to the moon condition, the sample was heated to 80-degree Celcius and resistance was tested and after that, the temperature was also raised. "We have not yet investigated how the urea would be extracted from the urine, as we are assessing whether this would be necessary because perhaps its other components could also be used to form the geopolymer concrete," said researcher Anna-Lena Kjoniksen.
The water in the urine and water found on the moon, both of the combinations can be used. The scientists need more testing to get the best building material for the moon bases. Where mass-producing can be done by the 3D printers. The UK Space agency was offering to provide important communications services between the Lunar Platform-Gateway, which is shooting something down the space station orbiting the moon, and scientists back on Earth.
