Will corporal-creet crack in a fire ?

[@KissingEmbers]

Just clay will make brick which hi works great, I have had home made clay bricks for 2 years in weather no crumbling (major)

[@mister3722]

Thank you for your consistently exceptional content Sir. Do you ever teach this in person? Thanks again Corporal

[@r3gr3tfulfly3r5]

@corporals corner where did you buy the volcanic ash? Walmart sells the volcanic rocks, and limestone in the fish department. Where do I get the ash?

[@davidsherman6398]

Any news on the hydraulic concrete? I tried searching your channel but couldn't find it.

[@HiveQu33n]

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

[@RBOzark]

I agree, that would be useful.

[@just82much72]

HiveQu33n : That would be interesting. Good idea Queen! -Mark

[@richardhawkins2248]

No need to run that test. Read Vitruvius. He explains much of this and gives ratios. He was a Roman engineer and builder. Modern concrete begins to breakdown after I think it's about 100 years. Roman buildings are still standing.

[@vg2b713]

Would love to know the formula that the Army used for concrete (eg. bunkers) in WWII. It seems indestructible. Is the formula classified? Is it available?

[@super66craig]

@@richardhawkins2248 Exactly so!

[@dansw0rkshop]

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

[@wolfgangouille]

Bones have calcium phosphate and not calcium carbonate so I'm not sure.

[@brineoconnor7491]

@@wolfgangouille what about egg shells

[@driopas]

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!!!!!!!!!

[@jurieccilliers]

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

[@cadepope4093]

[@ryanwhiddon6918]

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 🤙

[@user-wy4mp9ts3u]

If the concrete keeps getting stronger that implies that it is not fully cured and may take months to cure enough to be strong s even portland cement takes 28 days to gain its full strength

[@nismo4857]

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

[@unknowndeviceconnected]

go build an empire my dude.

[@smac3662]

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.

[@austinmenezes8074]

You should try doing some sort of stress test

[@barry6541]

He should wait a year or two then make a second batch with the same process and do a stress test, as the concrete gets stronger with time.

[@afri-can7739]

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

[@recall5811]

film it

[@JeremyDavidLewis]

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

[@aprildamski8365]

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

[@damonwalker2495]

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

[@smac3662]

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

[@fearlyenrage]

intention to inform: it was the rice husk ash that made the bricks better not only or just the starch. Starch delivers not to much of potassium or silica and that, both makes a better and stronger brick or concret. Checkout geopolymer. Fantastic stuff.

[@tooterplumber1128]

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.

[@recall5811]

Thank you for watching, please share my channel with others

[@alnoso]

is it really an emergency if you can afford to make concrete?

[@keonihillier981]

alnoso you can make this stuff anywhere.

[@SapioiT]

Yes: if you're lost in a forest, or on an island without, the help of the society (so no internet or phone). If you can make concrete, building a permanent shelter will be easier, so even if it takes some time, it's worth the work, more so if it's winter or winter is approaching.

[@MetaJamm]

In emergenecy you probably you die from hunger before (or after) you make these daim brick.

[@PsychoStueyHappyKittens]

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

[@rayswoodshop4467]

On the bright side, you have a meal that will stick to your ribs :)

[@valynazvalkynaz5375]

Edible bricks?

[@almirria6753]

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

[@jaramywarren6192]

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

[@simon4187]

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

[@greggsenne1268]

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.

[@patrickharmon9459]

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 🙏

[@dustyroads5753]

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.

[@TsetsiStoyanova]

Excellent info

[@partyinthecloudkingdom]

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

[@partyinthecloudkingdom]

"crafts" just means handmade things here, not specifically "arts and crafts" like it usually means

[@keithmorse9716]

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

[@Crosshatch1212]

This is how they built the big huge sculptures we see and sarcophagus along with other tech we lost .but no they have to come up with aliens and strange laser tools etc ,When in all honesty over 150 yr you cld lose this way off making anything as the younger generation come up with quicker cheaper ways off doing buildings etc etc .I sculpt and I do my own way that other sculptors are very amused at but it’s how it works and it’s difficult to them but it’s second nature to me now . Peace

[@dvdinjp]

Excellent and helpful information. God bless.

[@baron8107]

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.

[@recall5811]

Whatever works, lol. Thanks for the comments and for watching

[@brickw8599]

I was thinking the exact same thing.. For survival in the wildenes next to a river or seabed where there are sea shells you could make a heater!

[@nachtkind46]

muriatic acid is actually a name for it from the late 1500s to 1600s, but it is called that in the USA in diluted form (used for balancing ph in pools and cleaning the surrounding concrete)

[@timothyruffle4777]

The logic of having a heater made from sea shells to keep you warm is half flawed.... if you have a fire it’s what you need.... you would need to burn the sea shells for some time ... your wasting more energy then gaining at that point! A pre made one however would be cool I guess

[@deathharpproductions3094]

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!!

[@kenlieberman4215]

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.

[@johnschmidt2123]

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

[@tannerpetersen3744]

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

[@SapioiT]

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

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.

[@20p65s]

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

[@SciHeartJourney]

Thank you for showing us how to rebuild a landscape from the existing materials. I wonder if there's a substitute for vinegar?

[@SimonHaestoe]

Milk.

[@Strange-Viking]

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!

[@GreatSmithanon]

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?

[@hanha2374]

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

[@shanek6582]

Wonder if you could use it for mortar between bricks, if it would bond them together? Because busting up bricks, to make bricks, just seems like work.

[@anotherblonde]

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

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 .

[@dloc116]

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

[@aaronchambers9888]

I love this man

[@JasonStanturf]

There are other uses for lime u can make a fire with it as well the other is mineral oil but not to positive I'll look it again 🤔 u can use lime still an Ash like from almost every tier's a the second best but if u r trying to keep low u will have to look around or burn a lot of wood lol sand is a nother part u can add fresh water mussels an clams and oysters as well an the thing about lime it can repair the cracks it's self in concrete if saltwater was used in the beginning of mixing the concrete it's amazing stuff love your show corporal Kelly keep up the good work

[@Just1Spark]

Have you done any destructive testing of this?

[@Craftsman1984]

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.

[@rivahkillah]

Could you compare the densities of both bricks?

[@BlazingSun39]

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.

[@tcgreen7304]

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.

[@3000gtwelder]

Hell yeah! I'm building a pool!

[@whitegod8755]

They recently had articles about roman concrete and some university has done studies on it and I think they said they used quicklime directly and this was the magic bullet likely also with the seawater you mentioned that allowed the microcracks to heal in the rain and the reason why roman concrete stands today. I think the latest move should be UHPC Roman Concrete......

[@tommaika9121]

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).

[@BODE318]

Very cool, you learn something everyday.

[@Franklinveterinarycenter1of4]

I have used type S mortar mix with wonderful results. I could not find hydrated lime in my HomeDepot or Lowes. Hydrated Lime is available in Texas.

[@kynchan3332]

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.

[@diegomer]

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

[@JustOneAsbesto]

I just found the channel tonight. Looks interesting. I'll have to check it out some more. But I'd call this a success. That second concrete block you made in the Roman concrete video clearly had some pitting issues. I'd guess the problem was a combination of the aggregate size, and trapped air, probably also due to the aggregate size, though maybe you could compensate for that with extra layers and tamping or vibration to get the air out. Although that would decrease the insulative properties of the material. Materials science is always a balancing act.

[@johnmoore5293]

If you add enough water and vibrant / tamp you can get rid of more voids. Cement in a concrete truck has enough water that it can be poured. They set up sprinklers on cement bridges ( after it sets up) to accelerate the cure as water is part of the cure. On a hot day I had extra cement on a tarp in my drive that was hard to break with a sledge hammer by the time I leveled my cement side walk.

[@SC-zq6cu]

This is very nice and informative.

[@99tombstone]

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

[@haxonprime1243]

If something horrible ever did happen, and knocked humanity back to the stone age, knowing how to make concrete is good, but first learning how to make clay and clay bricks would be more beneficial I think. Takes less time and resources to make and you can build strong structures from it that last. Clay can also be made just about anywhere on earth. Only then would I start experimenting with concrete. Also it is worth noting that there are concretes through history that work with fire ash in place of volcanic ash that are pretty darn strong. However, for a true concrete the limestone is always a must. Great video and very informative!!

[@LeatherNeck-0331]

Outstanding Corporal,thanks for the heads up on other options to use for building materials. How about adobe,would those items be readily avaliable? Maybe a video on making some? For instructional purposes only of course, Semper Fi

Question: If you soak the brick in salt water like you do the Roman concrete does it get stronger like the roman concrete or no?

[@mrpix3011]

Man thank you so much!

[@ejorgensen9586]

Another way to test limestone without access to vinegar is by rubbing it against a hard surface like a different-looking rock face. If it leaves a white chalk mark, it is limestone (or at least contains calcium carbonate, which is why limestone is used here.)

[@necipfazlcoskunsu8330]

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

[@petrus4]

I just discovered this second video. Great to see it. :) This second batch didn't have quite the same plasticity as the first one, I don't think; it looked more crumbly. I could see the first batch being used more for load bearing applications, and this one being for a fire hearth; especially if a bit of sand was added to it to make it a little more specifically fireproof.

[@necipfazlcoskunsu8330]

second one is mortar to use as a binding material for stone or brick wals

[@necipfazlcoskunsu8330]

and as a plaster for wall is perfect

[@rosalee33]

I wonder where your research took you, in regards to similar building styles in China and India... I also wonder what they called this style of building there.. I'm trying to research traditional water cisterns so I can try to make one for access to water, with local materials in my bioregion.
