You should do a video testing the structural integrity of both Roman and Coporal-Crete using modern concrete as a control.

Now I know how to - Make roman concrete - hard dirt brick - make rope from trees - how to make iron from beach/moutains - how to make white paiper from trees - how to make good coal

Ha! I just watched the Roman Concrete video and thought " But I don't think I live an area with readily available volcanic rock"

Chicken egg shells, as well as bone, could be used for the source of lime I believe.

You should try doing some sort of stress test

Please test the Roman Concrete and Corporal Crete's heat tolerance (after being fired)

in greece we still use lime during bonding today concrete and if we want to be super sure about the good final quality and the strength of the concrete , we add some broken bricks and the dust of them. This technique is used since i was a boy of 6, literrally all of my life, im happy to learn the reason why during watching yr videos and super happy that this science is common knowledge in my country, keepup up the good work, congrats!!!!!!!!!

I was told this method makes the strongest concrete known to mankind, and just keeps getting stronger over time! Excellent demonstration. Can’t wait to try the formula 🤙

Damn... confused the quick lime with pancake mix. Now I have some terrible tasting pancakes and bricks that aren't worth squat!

Looks like a success to me. I'm glad you're venturing out and doing new projects. They're are plenty of different shelter ideas, but your new projects are very interesting. Thank you and God bless 🙏

Thank you for this VERY informative video. To be able to do this in an emergency situation is extremely valuable. A definite thumbs up video.Thank you again.

watched two videos and i'm already completely impressed great content

Dude may God always have you in his grace peace bro be blessed

Ur only one that showed how to do limestone. I have tons on my land, and tons of wood. Thanks alot. Im starting tomorrow

Nice, I saw your other video on Roman Concrete as well. Very nice and informative,, Roman vs Corporal Crete! Yeah!

Thank you so much I have been looking for ages for this

Thank you for your service

Great video by the way. Thanks for all the information you put out!

fantastic chemistry lesson

Thank you so much for your time to research the information; this is definitely a keeper! On a side note, the Chinese added the starch water from their cooked rice when they built the Great Wall of China to make the bricks stronger. Apparently, they were having issues with crumbling and by adding the starch water to the brick recipe instead of plain water; that made the difference. I guess that's why our ancestors never throw stuff out? HA HA

Guess I 'm not so good at finding 'recipes' for things. This is the 1st time I've been able to see bricks/concrete made & whate I can use for substitutes. Thankyou!!

Great idea if you are planning to build a long term fall back camp.

VERY COOL! Stumbled upon this out of the blue and a great skill to know! Semper Fidelis Forever brother!

corporal fudge that was cool mate I like that , very educational and informative now I got the answer for the question that I've asked you when you did the romancrete video thanks mate till the next one cheers

My man you're the best greetings from Greece 👍

Excellent and helpful information. God bless.

just found your channel, your videos are a promising writing and worldbuilding reference source for ideas and testing practical things like survival skills and crafts

very well explained thanks

Corporal-Crete coming to a Home Depot near you. lol. Fantastic and very interesting project Corp. Cheers Major Moose.

Good lesson. Thank you.

You can also use snail shells for limestone and sand for the binder

Success. I was one of the ones that asked about an alternative. Good info as usual.

Excellent info

Very informative vid. Thanks for posting.

watching this again for the third time. Really awesome job!

This is very nice and informative.

Btw thank you for your time n dedication to showing this

Love it, well done and thank you! :D

Great job and great information. Big thumbs up.

I saw guys using snail shells. Works!

Would love to see you make a wall tent or give ideas on one. They are a good source of long term shelter

Traditional cobb structures were stabilized with a layer of lime plaster inside and out. There are cobb buildings in the UK that are 600 years old and still occupied. Adobe structures can be plastered in the same way. Roofs can be thatch, shingles, shakes, slate, or tiles. Low tech housing should the need arise.

Um vídeo bem completo e explicativo Obrigado 😄

I love this man

Nice. I think you've also inadvertently taught people how to make Flameless Ration Heaters. Just take a Mylar bag or other thick container and chuck the powdered CH into it with properly-packaged food.

wow.....love your videos

Cool and informative video👍👍

These are the things our Science teachers should be teaching in school!! Not only is it useful for life; it's interesting as all get out. This is the stuff that makes society able to overcome hardships; by learning from our ancestors.

Very cool, you learn something everyday.

Thank you!

Great history lesson. Great vid

How do I like this video more than once? Very informative and thank you ☺️

So in addition to your info in this great vid It might be nice to know that the chinese used clams to naturally fortify bridges in both fresh and salt water to keep them from eroding. Basically creatinh a huge shell. The romans did this too in a lesser extent but the romans used concrete whereas chinese used stone. This type of concrete you made is almost the same from what Ive read and seen. And it uses salt water to chemically strenghten it (unlike modern concrete) but romans had many different types and ratios too. The salt water type isnt very good on land for example. Interesting stuff!

Great one, Corporal. Ever heard of, or done anything with aircrete? It uses stuff like spray foam, and different foaming agents to lighten the cement.

I bet young boys would really like this! Science project!

I know this was a long time ago, I actually subbed to you around this time, but RU-vid removed the notification... catching up on all the videos now! great quality content that is USEFUL, as opposed to tik tok nonsens the younger generations are into these days.

Yes, I also would like to see more of your test results; i.e., comparisons of breaking-strength, in various configurations, etc., of the first Roman-Crete, your Corporal-Crete and a basic concrete. Alternative materials research is very popular now, but this Roman-Crete is unique and I haven't seen much info available. Also, what might be a substitute for the volcanic ash? Great presentation; keep up the good work.

Id love to see psi stat comparrison of those blocks to thier industry counterparts! It'd make for an interesting read. Really like the sound of the Corporal-Crete

Man thank you so much!

good knowledge keep it coming bro.

Interesting and informative

Thanks Corporal!

Thanks! Very useful video. Now I know how to make my barrier wall :D

Thanks for the info ....

I love these Concepts and still wonder about water setting concrete also it would be cool to see a control testing of the Integrity of these materials

THANK YOU!

I would love for you to try the double burned wood ash concrete!!!!

We have limestone everywhere here (mammoth cave area) I will have to try this. The a lot of the limestone here has a gray/ off white area.

Great videos, thank you.

Great video man. Ive always wanted to see a tutorial on how the romans madd their concrete and suddenly your video pops up in my suggestions. Subscribed

Awesome !!!!!

I know this is a old video and you may not see my comment but thanks for the video it really helped me to make a foundry

My house was constructed pre-1860, out of bricks fired here on the place. The clay "mine" is now a pond, and has been since. I'm not sure exactly what the morder is made of, but i know it contains "cooked" limestone because I can observe bb sized pieces in the morder lines (guessing it wasn't hot enough or ground well enough, etc). That should lend some perspective on how well this stuff would last imo.

Very cool

Great video

thank you

Volcanic Ash can be bought for roughly 300usd per metric ton. Limestones are expensive , however, seashells can be bought for 50usd for 150-200kg bags .

So interesting. So thought provoking. Thought comes from ancient Egyptian "Thoth".

On the topic of finding materials for this in urban or suburban settings, you can find the calcium carbonate as well, in the form of ordinary blackboard chalk. I also wonder how this mix would do if you mixed something like charcoal ash as a substitute for the volcanic ash, since that's also readily available, and even fairly easy to make on your own. I know they're not the same, but it could make for an interesting experiment.

Very cool man good video

Would be cool to go out and make a cabin from this material provided the base materials are within reasonable walking distance.

Good to know knowledge

excellent

Nice!

Test both out to see which one is better , but over all good job sir

thanks!

first one is load bearing material and the second one is binding material for stone and brickwalls as a mortar and also can be used for wall as a plaster

Great video! However I'm still left wondering how well the material preforms as intended and under various conditions as well. I get that Roman create should be a hint but It would still be nice to see.

Had too watch this video more than once not because i am a slow learner because it was fascinating

You can also use chicken and duck shells to get CaO, if collecting a lot of seashells is illegal in your area. Bakers usually use a bucket load of eggs and get rid of loads of shells, especially the French ones.

Very good video! You made a _clinker_ brick. Not all bricks are clunkers. Clinkers are special and are rare because they are not made anymore

Just found out about your channel. Very informative! Count me in as a new subscriber!

Actually the Romans made stucco using "potshards" aka grog. This was recorded by Vitruvius, and was rediscovered in Renaisance (rebirth). The method caught on with the Venetians who used broken roofing tile. This commonly known as Venetian plaster. This was finsihed with a mixture of pigment and saponified beeswax (cera colla - wax glue - reflecting its use as a binder, for wood they used what the French call cheese glue, or milk paint) and hot iron plates. Very water resistant.

This is really interesting. I didn't know you could get lime from seashells. In the long run, how strong is this "corporalcrete"? How well does it stand up to say, a club or bat or perhaps small arms fire?

Good survivalist technology.

Hell yeah! I'm building a pool!

I found Lava Rock (your pozlan) at ACE Hardware store, a 4-5 # bag for about $15. Its used for the bottom of gas grilles, but I will use it for making a pizza stone out of your improvised Roman concrete. I also found genuine lava volcanic ash from Washington State on the web. I suppose I could drive there and fill up several cans of ash from my own sources in the woods there. Its a long drive! I baked some oyster and clam shells in my home oven on the "clean" cycle, but the shells broke down into a grey powder and rocky mixture instead. I need to make a home kiln or a gas fired smelter to get these shells to be pure white - calcium oxide. My home oven is not hot enough. If you have old rusty and crusty food coated cast iron cookery, the home oven clean cycle is adequate to burn off years of baked on crud. The rest of the rust can be taken off with vinegar (another story and another video ... but relevant in trying to use your home oven for attempting to make calcium oxide).

wow cool

Could you, please, do a weight comparison? I wonder how this would affect the weight limitations of buildings...
