Primitive Technology
Australia
Приєднався 1 тра 2015
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. To find specific videos, visit my playlist tab for building videos focused on pyrotechnology, shelter, weapons, food & agriculture, tools & machines, and weaving & fiber.
FAQ
Q.Where is this?
A.This is in Far North Queensland Australia.
Q.Do you live in the wild?
A.I don't live in the wild but just go into the bush to make these projects. Also I camp out here occasionally.
Q.How did you learn all this?
A.Researching books and internet plus trial and error. I'm not indigenous and have no army training.

About This Video:
I have made wood ash cement before under the assumption that it was the calcium in the ash that gave it its cementitious properties. It may however be a type of geopolymer cement, where the cement is activated by and acid or a base (in this case a base). The acronym NASH is used to remember the material needed: sodium, alumina, silica and H2O. All of these are present in the materials used here.
I did some experiments to see how to produce the cement using ash and fired clay from broken bricks. The first method was to take ash from a cold fire and form it into pellets. One pellet was left aside to dry while the others were calcined by firing them in a forge with wood. The calcined pellets were then mixed with terracotta in different proportions (ash: clay 1:0, 1:1, 1:2, 1:3). All samples survived a water test after setting for a week except for the sample made from cold ash that had not been calcined. This demonstrates the need to calcine the ash at a high temperature before use.
Next I built a furnace with a grate for calcining ash to prove it could be done with natural draft rather than the more laborious blower method. An ash brick or clinker was made from a cold fire and was placed on the grate and fired. The clinker was then taken out, mixed with terracotta and formed into various shapes. One sample was mixed with sand as an alternative to terracotta. The samples all survived the water test after 2 days of setting though the sand sample isn't as strong as the terracotta ones.
Finally, I took the ash from the furnace and used it as is without forming it into a clinker and calcining it. My theory was that ash from the furnace gets hot enough just from burning on the grate that it does not need further calcining. The ash was mixed as is with terracotta and left to set for only 6 hours. It passed the water test without dissolving suggesting a quick setting time.
These experiments have shown how it might be possible to scale up and simplify the production of ash cement. I'm considering it as an alternative to brick making as it's potentially a simpler method (no brick forming, hours stoking the kiln etc.). The structures would have to be adapted to the new material and might be insitu formed walls. More experiments need to be done.

Did he get a new pair of shorts?
Хотелось бы сказать словами классика: "Нихуя не понял, но очень интересно!"
could try to make beams out of corcrete and some type of reinforcement like tensioned fiber strings or rope, or even wood if you somehow manage to get it under tension, try to apply the principle of reinforced concrete see if you can get anything. i've heard about rubber and textile being used together, idk bout concrete tho, feel like the textiles might rot and leave holes in the concrete, worth trying tho.
Ничего не понятно. Когда уже будут технологии НЛО?
Whoever makes that camera needs to give him as ass load of money
😮😮Diese serie wird nie alt.Die muhe,die sie in diese gesteckt,ist unglaublich🙌Dangke❤️❤️😄👊💔💔
😢😢She's MIGHT just be the most humble and heartwarming person to exist❤❤❤️🥱
Plus, now with that grate, you can make a killer pizza
bro will have made transistors at age 50
Yes sir! Structure time
It must be pretty rough, for anyone who has to rebuild their home and equipment over and over just because of rain. Sturdy buildings are hard to make, but well worth it.
You might wanna watch me 🫦
John: I'll experiment scaling up to see what structures can be made. Me: He's about to build the Coliseum in the Outback.
Did I miss the Book release??
👍👍👍
You could try this ratio: 1 Ash, 1 Sand, 2 Clay
I swear I have seen you make ash bricks, and calcine ash pellets in bulk in the brick furnace. I think that was when you made the brick hut. Was there a specific reason you chose to calcine the pellets one by one this time?
😮😅Diese serie wird nie alt.Die muhe,die sie in diese gesteckt,ist unglaublich🙌Dangke❤️❤️😠🤗😘
😍🤗She's MIGHT just be the most humble and heartwarming person to exist❤❤❤️🥲😘🙂
wow did not suspect there was such a massive fascination with primitive living! peculiar
i just wanna say man, this is your BEST video yet! (imo), been watchin u since basically the beginning of the channel for so many years now. much love <3
for me this are very calming videos no voice over & music just a dude making stuff & using cc to explain things is a great touch
Primitive Technology going scientific love it!
Jeder Tag mit dir wäre ein Happy End. Es geht um die besondere Stimmung, die ich von dir bekomme.❤️❤️ 🥰
What's the point of making new things if you're just going to keep reusing your old stuff? It's actually getting really annoying to watch you make something new and then never use it.
truly amazing
soon enough this guy is going to find some villagers and build his iron farm.
Great stuff, John! Thanks for doing all this
I'm interested in seeing how every technology on this channel scales using only primitive methods. While these examples are interesting I'd like to see how far they can be taken.
Couldn't you make a crusher so you don't need to repeat some processes you've already cracked open?
John, if you end up with some sort of geodesic concrete bunker by the end of this I'll be amazed and astounded, but not surprised.
Hi, what was the grate made of?
While I appreciate all the work put into these videos, I do miss the older content where he made things like bows, arrows, slings, etc. I can only watch so many making bricks and forging videos.
Getting an ember from 30 seconds with fire sticks never ceases to amaze.
He's gotten close to the fire with the camera before, but 8:33 is next level
I swear, I'm getting welts and blisters on my hands every time I watch this guy start a fire.
You are so talented. Please take care of your health
what would happen if you added salinated water?
What conclusion do we draw from this? Which one, sir? The dude made lumps of shit. Yes, sir. It remains only to understand why he made them. ....
Thank you for interesting video!
I like how we're moving into sampling. Even the ancients were doing R&D.
There is things I am waiting for you to make.. a primitive distillery.. and some glazing paint for the pottery..
Do you have any issues with the products causing a chemical reaction with your skin/hands? chemically burning or damaging them? or is it very safe to handle?
Finally, he shows us how to make thingamabobs
I hope he discovers Roman cement, that will help him to build the monument ☝️🤓
a tame lizard
about to hit us with that cinder block..
Maybe advance to bronze age?
Can't wait for him to use this material to build his own Barbican Centre entirely by hand.
Awesome video.
