I developed an experimental cement from made only from re-fired wood ash as its cementitious material. It was mixed with crushed terracotta as an aggregate and formed into a cube. The cement set hard after 3 days and did not dissolve in water after this period.
Process: First I burnt bark and leaves in a kiln at high temperatures to produce well burnt, mostly white wood ash. The ash was then mixed into water and stirred well. The excess water was poured off and the resulting paste was made into pellets and allowed to dry. A pellet was then re-heated in the forge until it glowed about orange hot. This was then taken out, cooled and dropped in a pot of water. The pellet dissolved and boiled due to a chemical reaction with the water. The paste was stirred and crushed terracotta (old tiles from previous projects) was added and mixed to form a mouldable mortar. This was formed into a cube and allowed to set for three days (in the video, a cube made exactly the same way 3 days previously was used due to time constraints). The resultant cube was strong and made a slight ringing sound when tapped with a finger nail. It was placed in water for 24 hours to simulate a very heavy rain event and did not dissolve or release residues into the water.
My current theory: The main component of wood ash consists of calcium in some form (e.g. calcium carbonate, calcium oxide). This can be up to 45% from my research. Calcium is in higher concentration in the bark and leaves of a tree. When the ash is mixed with water, the soluble component of wood ash (10% pot ash) dissolves into the water. But seeing that it does nothing for the cementing process, it is drained off leaving the insoluble calcium (and other components) in the paste. Doing this probably raises the relative percentage of calcium in the paste to about 50% or more. Most of the other 50 % consists of silica and alumina which are pozzolans, materials that chemically react with calcium hydroxide to increase the durability of the cement product. The paste was then made into a pellet and fired again to high temperature to convert all the calcium compounds to calcium oxide. It also reduces any charcoal in the pellet to ash if it hadn’t already been burnt the first time. This step seemed important as un-fired ash pellets only partially hardened and would fall apart in water, though retaining a weak undissolved 5mm thick crust. I can only surmise that re-firing the ash just gave a greater conversion of the calcium components to calcium oxide. The pellet is slaked in water converting the calcium oxide to calcium hydroxide. This cement was mixed with crushed terracotta which may also help in some way that I’m not aware of as I only did this one experiment and did not test other aggregates yet (e.g. sand, gravel etc.). Terracotta is porous and might hold together better than other materials. The mixture is allowed to set in air where carbon dioxide reacts with calcium hydroxide to form calcium carbonate cementing the aggregate together. After this, the cement will not dissolve in water.
Use: I think this material might have a potential use as a mortar holding rocks or bricks together in wet environments where limestone or snail shells are unavailable for making cement. Wood ash is a pretty ubiquitous material to most natural environments inhabited by people using biomass fuels. Wood ash cement turns a waste product into a valuable building material. From my research, wood ash is already being used as a partial replacement for cement in the building industry without decreases in strength of the final product. But I’ve only just started experimenting with it and don’t know its full capabilities and limitations. Calcium content of wood ash differs depending on the species of tree, the part of the tree burnt and the soil it’s grown on. Cautious experimentation is still required before committing to a hut built from this material.

I think I have the chemistry right. If any chemists are watching correct me if I'm wrong. The calcium compounds are converted to calcium oxide in the second firing, turn to calcium hydroxide in the water and then set to calcium carbonate in the air. There maybe a pozzolanic effect due to the alumina and silica in the ash too. The end product is a cube made only from wood ash (fired twice) and crushed pottery. It sets hard after 3 days and will not dissolve in water even when fully submerged for 24 hours. Thanks.

xland44 If your out in the middle of nowhere and you can make this what can you make? A hut a weapon many things.
xland44 I think he's just doing a small batch to make sure he has the mixtures and processes right. Once he gets it right I'm sure he'll start doing on a larger scale
chemist here. Spot on. The calcium hydroxide reacts with the CO2 in the air, giving calcium carbonate. Careful with both calcium oxide and calcium hydroxide, they are very aggressive, on the eyes in particular. Also, be careful on the oxide to hydroxide reaction. It produces a lot of heat and can boil the water quickly, spraying everywhere,
I'm just gonna say your right because I'm shit at chemistry
Hello, I’m chemist specialized in chemistry of construction. What you did is a pozzolanic cement. Your mix with lime react with the calcined clay (your clay certainly contained some kaolinite which was partly turned to metakaolin because your furnace not enough hot to fully burn the clay). It’s some kind of Roman cement. If you would add some clay and limestone into the wood fire, you could make some kind of hydraulic powder, just the setting and performance wouldn’t be regular as you can’t finely adjust the composition but it would be enough to make some mortar. Also congratulation for your work :) that’s very nice
I like your funny words magic man!

Man, being knowledgeable is always such a big advantage
@@roksy8856 🤓🤓🤓
as an additional project for anyone that wants to do this, the water that you pour of the ash can be used for other projects, it contains lye which can be mixed with fat to create soap, but is also used to preserve and even prepare food in some parts of the world.
Hominy comes to mind for the food.
@@ermakers1297 what is hominy
@@SnowyGolem hominy is corn treated with lye. Olives are also cured using lye.
Bro you ain't gotta lye to kick it, alright?
@@SnowyGolem
It's like corn nuts but if they were uncooked, and you soak it in water, it's soaked in lye to nixtamatlize the corn so that the starch is available for digestion...or soaked in lime.
It makes the kernels bigger I'm pretty sure... it's used in soups and stews and it's really good. It has another name but I can't remember. Posole, or chicos
Props for putting the crafting recipe at the end

I suffer from insomnia but watching your videos at night helps sometimes. There’s a calmness and humbleness to them. The fire cracking, water rushing, it’s the primitive things that bring me down to earth and relax my mind😉
Ah yes, the “primitive things” like watching RUclips videos
@@yauker people have insomnia. It’s not being lazy or eating too much sugar in the night. It’s literally a sleep disorder that people have trouble falling asleep.

Consistency is key for ur circadian rhythm amigo....go to bed and wake up same time for a couple months your body will develop a crazy internal clock. Youll be waking up 30 seconds before ur alarm goes off every morning.. also try not ot looking at ur phone or any blue light screens like tvs for 3 hours before bed, trust me youll be out like a light.
'I suffer from insomnia but watching your videos sends me to sleep?' Not a compliment, necessarily...! (Joking)
As someone who builds concrete walls and foundations, this really inspires me. Ive wanted to figure out an alternative for doing footings using natural materials, as well as building earthship type structures and something akin to this is what I'm leaning towards. It would take tons of prep, but I live in the wealthy side of the Appalachian mountains and the bougie hippies might be willling to foot the bill. Thank you Primitive Technology!
I just discovered your channel... and out of years skimming youtube... this is the first channel I can focus on each episode and practically write notes. I bought your book and I am hooked... this is AMAZING!

Primitive Technology, I know you've got loads of comments to read, but concrete technologist here - from a mix design perspective, as I believe I've read in another comment that you posted, you want to use very little water when hydrating the pellets. This is your water:cement (w/c) ratio, and determines your strength. You basically want to use just enough water to get cementitious material mixable - a .45 w/c is roughly equivalent to 4000 psi. However, it's based on volume, not weight, so if you have a pellet of a certain size, you'll want to use a comparable "pellet" of water that's about half of that for high strength. It is much harder to work and shape at that ratio though. If you do this, if possible, after the piece has hardened to the touch, you can get more strength by submerging the item in water for a few days to further hydrate any remaining cementitious particles.
So a water: ash pellet ratio by volume of 1:2 is recommended.Thanks, I'll give it a go. What about if I wanted to use this as a mortar for bricks, is it the same? I'm thinking of firing clay bricks then use the ash to make mortar for the them.Thanks.
+Primitive Technology OMFG
Usually mortar mixes are similar in w/c ratio and all sand. This creates less strength, but more workability. The ideal mixture for finishing comes down to particle size - ideally, the tightest finish has particles of every possible size from your largest grain of sand down to the smallest pozzoloan, as well as keeping water content low. You want just enough cement paste to cover the aggregate, no more. Rule of thumb is 1 water:2 cement:6 sand(or fines).
If you want something more porous for filter use as someone else mentioned, you'd want larger aggregate, very little sand and less cement paste with a higher w/c ratio.
For a bush concrete recipe I've seen used before, get a container and use 1 water:2 cement:5 sand:5 rock. This will produce something similar to most modern construction.
If mixing manually, I'd mix the paste first like you did, then make sure you get good coverage on your aggregates.
Thanks Jeremy. I'm writing all this down for future reference, much appreciated.
No problem. Glad I could offer some help. Great content by the way. Really enjoy what you do and the format as well.

Fascinating use of ash which made me think of other uses such as lye soap. Then that made think of an episode you might consider on primitive hygiene. How to make soaps, tooth paste equivalent, tooth brush, wound dressings, antiseptics, etc. just a thought. :)
Jonathan Landwer yeh our pampered asses wont survive in the wild all dirty n stinky . Need that luxury bathroom .
Most of those require some animal products. Soap needs fat and lye. Toothpaste needs charcoal and powdered bone or shell. Toothbrush needs hair/bristles. It would be interesting to see some trapping/hunting though! But likely that's not legal where he is.
He's up in Queensland - so maybe pest species that shouldn't be in the bush. Cane Toads maybe?
How to make the most important medicine humans have ever created. Antibiotics.
A lot of those would be incredibly location-specific. Useless to anyone outside of Australia. Soap and toothpaste? Yeah, those have equivalent ingredients just about anywhere..... but wound dressings and antiseptics are likely to be herbal. Tea Tree oil is a hell of an antifungal, but you really don't find it outside of Australia. (I think it's been transplanted to Southern California among other places? But not many.)
I’ve been watching this guy for eight years since his sling video and I’m happy. He’s keeping up the work one video every month.😁

I think primitive technology is one of the most advanced. The reason is you can access it everywhere and always utilize it. It is easy to maintain and repair when needed. It provides the means to live somewhat comfortably in times of dire need. Knowledge everyone should know for the time you may find yourself unexpectedly stranded. You might be able to survive depending on the climate.
Sleep or watch this. I think that's been the easiest decision I've ever made.

This is not real cement. This is more like mortar. Real, industrial cement is a lot more complicated.
@@MagnificentXXBastard this is just like the cement the romans made so yeah, it will only last a couple thousand years or so.
god bless you for showing this, I don't know about a hut, but it looks like it would be a good primative caulk to seeal up some thing already built and it looks to be a fairly heat resistant substance for fire places.

Your videos are so entertaining. I can't stop watching.
Don't forget the captions, everyone!
I find his videos more enjoyable without them. He tells you everything you need to know though the visuals.
I’ve heard of and used “survival cement”. It’s basically a blend of mud, clay, grass, and pine needles for building. But never wood ash cement! Pretty interesting stuff. Thanks for posting.
Yes I've heard of it too. This stuff is superior as it won't dissolve in the rain. Better to burn the pine needles and grass to ash and then mix them in. One study in northern Europe showed the composition of pine ash was almost identical to Portland cement. Thanks.
You've so much improved on the air blower! Practice makes art!
That's amazing - theoritically, this method could be used to make cement 6k years ago, and even earlier!
Pyramids are also ancient geopolymer casing stones....
This method was mentioned in the Holy Quran 1400 years ago
I get so tired of other channels putting "Primitive Technology" in their video titles. I agree it is primitive technology but they can just put it in the description and not in the title because they are intentionally doing it to trick people into clicking their videos so in a way it is misleading. I automatically click the 3 dots and say not interested in this channel every time i see that shit. Their channel will still come up in searches without having to put that in the title so they should really stop that. There is only 1 Primitive Technology channel and no one compares to you my friend. :-)
T. Price finally, a smart human
Yeah. Or maybe people don’t check desc. I don’t know.
other primitive channels are OK but they shouldn't put Primitive Technology in title
exactly. they have good content so people will still find them and watch the videos so no need to use his channel name in their title. description is fine but title is a nono in my opinion
Wouldnt it also be possible that such channels existed before this channel and just named it as the content it was providing. Yes such channels as the one u mentioned exist but some just name the channel primitive technology so people like u and me can find them easier and more accesible. ( typed this on my phone and my god was it alot of work so read it till the end)
Im a simple human, i see primitive technology videos, i click.
