Iron bacteria lives by oxidizing dissolved iron 2 oxide in the water table, converting it to insoluble iron 3 oxide, which precipitates out of solution forming an orange slime. This material can be concentrated to a paste that can be shaped into objects. After drying out completely, the material becomes insoluble in water just as cement does. I don't know for sure why it does this but I suspect that while it's wet, there's still some dissolved iron 2 oxide in the material. When air gets to the iron 2 oxide and converts it to iron 3 oxide it precipitates out. It then becomes a solid, cementing itself to the other iron 3 already present. This is probably why iron bacteria sometimes forms solid lumps known as bog ore. Bog ore was once primarily used for smelting into iron but was also occasionally used as a building material (not as a cement but as solid building blocks). The potential use for this material could be as a cement-like material or mortar used in structures when iron bacteria can be found in large quantities. Fire is not used in the process as is the case with limestone or wood ash cement, and so reduces fuel consumption. It may be an appropriate use for iron bacteria contaminated with mud that might otherwise be unsuitable for smelting. Aggregates such as sand and gravel could also be added to bulk out the volume. More experiments need to be made. About Primitive Technology: Primitive technology is a hobby where you build things in the wild completely from scratch using no modern tools or materials. These are the strict rules: If you want a fire, use a fire stick - An axe, pick up a stone and shape it - A hut, build one from trees, mud, rocks etc. The challenge is seeing how far you can go without utilizing modern technology. I do not live in the wild, but enjoy building shelter, tools, and more, only utilizing natural materials.

к чему?
ведь железа будет полно, ржавого, но много.
может в городах будет слишком опасно, и добывать железяку будет безопаснее в диких джунглях, из бактерий?
Так же люди без телефонов..
Ну трудоёмкость добычи такого "цемента", судя по видео, очень высокая. Ни о каком строительстве из такого материала речи не идёт.
