In a few years, the first bases will appear on the moon, which will be built by Earthmen. Today, scientists around the world are thinking about what materials can be used to build basic objects on the surface of the moon. It is very difficult to deliver traditional building materials to the moon from Earth. It will require huge financial costs to transport them from Earth to the moon. It is unknown whether the earth's building materials will be suitable for use on the moon.
Now space agencies are busy analyzing the composition of the lunar surface. It can be used as the basis of building materials. An unusual discovery was made by scientists who said that the urine of astronauts can be used to strengthen concrete during the construction of a lunar base.
Materials scientist Ramon Pamis from the Polytechnic University of Cartagena in Spain says it will be geopolymer concrete. It is ideal for use on the moon. There is regolith on the surface of the moon, which is a light, loose material. In some areas of the moon, there are ice layers from which you can get water.
To these components, you can add waste, such as the urine of personnel working on the lunar base. Its main composition is water and urea. The urea molecule destroys the hydrogen bonds, which leads to a decrease in the viscosity of many water mixtures. On Earth, we have already conducted experiments to find out what other materials can be used to create a lunar base.
Scientists took into account various factors, including the temperature regime. The building material for the moon must withstand high thermal loads. The moon has no atmosphere of its own and is subject to radiation from space and meteor showers. The lunar base will have to withstand the blows of meteor showers.
Scientists believe that urea can cope with this. The experiments conducted using the created 3D model confirmed that its use will make the structures strong, they will be able to tolerate fluctuations in lunar temperatures.
