Re: Material Choices for Mars
Mars paper
XII. Mars Minerals, Space Plants and Mars Activities
A. Mars Minerals
The composition of Mars has a diversity of mineral resources tabulated below. Based on the ease of accessibility and extraction, we can set up numerous fabrication plants on the planetary surface. Some of the accessible minerals and their applications listed below.Table 1 Mars Minerals and their Applications
S.No Minerals Applications
01. Olivine Refractory Materials
02. Marcasite Diamond and Graphite
03. Feldspar Dinnerware, Bathroom, and building tiles, Glass production, Flux
04. Ilmenite Aircraft parts, Titanium metal, Reflective pigments, Synthetic rutile
05. Akaganeite Adsorption of arsenic to prevent pollution
06. Hematite Storage Devices, Electrical components, Inorganic pigments
07. Magnetite Water purification, Biomedical, and environmental applications
08. Goethite Cleaning chemical elements in polluted water
09. Saponite Water Decontamination, Rubber, Cosmetics, and Medicine
10. Montmorillonite Nuclear applications, Cotton fiber, Adsorption in heavy metals and dyes
11. Serpentinite Architecture, Ornaments, Asbestos

Re: Material Choices for Mars
Interesting post from Low Tech magazine.
https://www.notechmagazine.com/2011/12/ … -sudu.html
'The ‘Sustainable Urban Dwelling Unit’ (SUDU) in Ethiopia demonstrates that it is possible to construct multi-story buildings using only soil and stone. By combining timbrel vaults and compressed earth blocks, there is no need for steel, reinforced concrete or even wood to support floors, ceilings and roofs. The SUDU could be a game-changer for African cities, where population grows fast and building materials are scarce.'
These structures appear to be constructed from stone, compressed soil blocks, tiles and crude mortar. A useful set of techniques for construction on early Mars. Also, from the same site:
https://www.notechmagazine.com/2013/03/ … aults.html
A type of sloped barrel vault, typically built from adobe without need for any supporting formwork. On Mars, we could substitute compressed soil blocks for sun dried adobe, or maybe even sorted natural stone and mortar made from filtered soil and water.
"Plan and prepare for every possibility, and you will never act. It is nobler to have courage as we stumble into half the things we fear than to analyse every possible obstacle and begin nothing. Great things are achieved by embracing great dangers."

Re: Material Choices for Mars
Thanks for the magazine links. The walls are quite thick and with windows. Not sure even being thick is all it take to withstand mars.
