The present invention relates to a method of constructing a space construction and product thereof, and more particularly to a method of constructing a space construction which can coagulate without a huge quantity of water and is capable of screening dwellers from gamma rays.
Concrete is a building material largely utilized on Earth to build important constructions such as buildings, roads, and bridges. With the capability to quickly harden, concrete is undoubtedly one of the most popular building materials. The hardening of concrete is caused by a chemical reaction called hydration between cement and a huge quantity of water. However, when it comes to constructions on other planets such as Mars, the technical issue such as how to obtain sufficient water to react with cement is still a critical problem left unsolved.
Moreover, gamma rays in the universe are fatal high-energy form of electromagnetic radiations to living creatures. Without the protection of the Earth's atmosphere, gamma rays would wipe out all living creatures on Earth. Therefore, how to build constructions capable of protecting dwellers from gamma rays on a planet without the atmosphere is also a crucial issue.
To overcome the shortcomings, the present invention provides a method of constructing a space construction and product thereof to mitigate or obviate the aforementioned problems.
The main objective of the present invention is to provide a space construction and a method of constructing a space construction which can coagulate without a huge quantity of water and capable of screening dwellers from gamma rays.

Each one of the multiple gamma ray screening elements comprises a glass ball and at least one kind of gas that composes the atmosphere. The at least one kind of gas composing the atmosphere is filled in the glass ball.
In the first mixing step, mix the strengthening material and the composite material with the agitator to form a first building material.

Other objectives, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
With reference to
A. A preparing step: prepare a spacecraft, an agitator, a strengthening material, a composite material, multiple three-dimensional fiber webs 10, multiple gamma ray screening elements, an absorbing board 40, and a reflective spray 50. The strengthening material is composed of water, air, and a moldable and curable material such as plaster and clay. The moldable and curable material can be molded into different shapes before coagulating. After coagulating, the moldable and curable material can be formed in a fixed shape. Water and air are mixed with the moldable and curable material before the moldable and curable material coagulates. The composite material comprises cement, a matrix material, and a reinforcement material. The matrix material is composed of 18% to 28% water, 0.1% to 1% hydrogenated light paraffin, 12% to 22% titanium dioxide, 1% to 10% amorphous silicon dioxide, 43% to 53% acrylic copolymer, 2% to 12% butyl acrylate, 2-hydroxyethyl acrylate, styrene, acrylic acid, and poly(methyl methacrylate) (PMMA) by weight.
The reinforcement material is composed of acrylic resin, Hydroxyethyl Cellulose (HEC), calcium carbonate, and water. The reinforcement material is mixed with the cement and the matrix material to form the composite material. With reference to
Each one of the multiple gamma ray screening elements comprises a glass ball and at least one kind of gas that composes the atmosphere. The glass ball is 0.5 millimeter (mm) in diameter. The at least one kind of gas that composes the atmosphere is filled in the glass ball. In the preferred embodiment, the at least one kind of gas that composes the atmosphere is ozone. Since gamma rays deplete ozone, ozone can prevent gamma rays from penetrating the gamma ray screening elements directly. Furthermore, gases that compose the atmosphere are filled in the glass ball. Because the atmosphere can absorb gamma rays, filling the glass ball with gases that compose the atmosphere is a way to screen gamma rays. The absorbing board 40 is made of lead and has a thickness. The thickness of the absorbing board 40 is 0.1 millimeter (mm). Lead can effectively attenuate gamma rays due to its high atomic number and high density. The reflective spray 50 is composed of 53% to 63% acrylic resin, 27.5% to 29.7% silicon, and 7.3% to 9.5% iron sand by weight, and the reflective spray 50 is capable of reflecting gamma rays.
B. A transportation step: Load the spacecraft with the agitator, the strengthening material, the composite material, the multiple three-dimensional fiber webs 10, the multiple gamma ray screening elements, the absorbing board 40, and the reflective spray 50. Then launch the spacecraft to a planet where people would like to construct the space construction. Preferably, the planet is Mars.
C. A first mixing step: Mix the strengthening material and the composite material with the agitator to form a first building material.
D. A second mixing step: Mix the multiple gamma ray screening elements and soil 60 on the planet with the agitator to form a second building material. Preferably, the soil 60 is Martian soil.
E. A matrix layer building step: Build at least one matrix layer 20 with the first building material in the first mixing step. Each one of the at least one matrix layer 20 has two sides.
F. A three-dimensional fiber webs paving step: Pave two of the three-dimensional fiber webs 10 on the two sides of the at least one matrix layer 20 respectively as shown in
G. A gamma ray screening layer building step: Build at least one gamma ray screening layer 30 adjacent to one of the two three-dimensional fiber webs 10 with the second building material in the second mixing step. Numbers of the matrix layers 20, the three-dimensional fiber webs 10, and the gamma ray screening layers 30 are changeable according to practical need. Numbers of the matrix layers 20, the three-dimensional fiber webs 10, and the gamma ray screening layers 30 can be increased by repeating steps E to G. In this way, an initial structure with the matrix layers 20 and the gamma ray screening layers 30 arranged in an alternate order is built as shown in
H. An absorbing board paving step: Pave the absorbing board 40 on one of the two surfaces of one of the three-dimensional fiber webs 10 away from the at least one matrix layer 20.
I. A soil paving step: Pave the soil 60 on the planet on an outer surface of the initial structure.
J. A reflective spray spraying step: Spray the reflective spray 50 on the soil 60.
By following the steps A to J, the space construction is built as shown in
With the aforementioned technical characteristics, the method of constructing the space construction and product thereof has the following advantages.
1. The titanium dioxide and the silicon dioxide of the composite material in the first building material facilitate coagulating. The method of constructing the space construction in the present invention does not require a process of injecting a huge quantity of water to harden the space construction.
2. Since the at least one gamma ray screening layer 30 contains the multiple gamma ray screening elements, gamma rays are screened outside of the space construction. With reference to
3. The absorbing board 40 can provide a last protection from the gamma rays. Since the absorbing board 40 made of lead can attenuate gamma rays, it can shield dwellers from gamma rays.
4. The reflective spray 50 sprayed on the soil 60 can reflect gamma rays. Furthermore, the soil 60 paved on the initial structure makes an outer surface of the space construction uneven. The uneven outer surface of the space construction causes the diffusion of the gamma rays as shown in
5. The two three-dimensional fiber webs 10 on the two sides of the at least one matrix layer 20 increase the structural strength of the space construction.
6. The first building material in the first mixing step is strong and airtight.
