Roman concrete made from limestone

ancient method of making cement like the egyptians and the roman empire did to build roads and structures using mud kiln and limestone rocks

[@utubeape]

Very interesting. Could the rings be for a chimney? Either that or toilet seats, and you have made a few to see which is most comfortable

[@PaddysBushcraft]

🤣🤣🤣

[@funkycup3900]

In my opinion, you are very underrated

[@PaddysBushcraft]

Thanks pal 😊

He must be making a Fred Flintstone car with all those spare wheels could last a while. :D

[@jimflask1164]

I thought the romans used pyroclastic ash also.

[@thomasjmeade]

My guess is they’re either for a chimney or for making a well

[@PaddysBushcraft]

[@robertharvey2716]

Your going to build a car.

[@PaddysBushcraft]

@@robertharvey2716 😂 a 6 wheeler why not

[@briansmith9669]

Very cool and I can’t wait to see what it is👍🏻✝️

[@PaddysBushcraft]

👍me too ..I hope it works 🤣

[@AndreaVon769]

Chimney seems the most reasonable, but I have no idea.

[@phnix6242]

Could it work also for stabilizing walls of a well? Looks like the ready made concrete prts just smaller. Maybe too small but wirh good digging/boring tools?

[@RobertsBulgaria]

Admit it, you're making Irish Polo Mints. 😉🤦‍🤷 Actually, when you got to the Quicklime part, I thought, oh, he is going to do a Crippen and dispose of his Wife's body in the bath or something. 😏👍‍

[@PaddysBushcraft]

🤣🤣🤣 funniest guess yet Robert

[@Afro408]

They're concrete rings. Cement is the stuff that holds the sand and gravel together.

[@PaddysBushcraft]

Correct

[@garruling]

Very cleaver . Just round you today not sure if there is limestone here in nc where I am but maybe I can make something similar

[@PaddysBushcraft]

Thanks 👍👍

[@funkycup3900]

By the way, you can also use sea shells or snail shells as limestone

[@PaddysBushcraft]

@@funkycup3900 yep I seen that primitive technology video he's amazing

[@AndreaVon769]

Could they possibly be for laying a pipeline of some sort?

[@PaddysBushcraft]

No .but you gave me a good idea 😉..thanks

[@JanTrewhitt]

Do the stones just dry out in the open and become hard? Do you have to bake them somehow?

[@PaddysBushcraft]

They air dry it takes a few days

[@dallyh.2960]

They react with carbon dioxide in the air to form calcium carbonate.

[@moniquedelatour3502]

You havent shown what you did with the limestone after you put ithem in the water. Can you explain the orocess in detail please?

[@PaddysBushcraft]

It dissolves into a sloppy paste know as lime putty ready to add to the sand

[@keithhowell4138]

Well then ,it looks like I will have to watch the next video

[@PaddysBushcraft]

👍👍

[@harrydrury4734]

making a chimney ? - making a single pillar ? or ..... ?

[@OldNavajoTricks]

Pipework or chimney?

[@PaddysBushcraft]

90% correct .video here. Already built and dismantled this shelter kzbin.info/www/bejne/rpy8k6iFmpytoLc

[@swissmilitischristilxxii3691]

Didn't romans put volcanic ashes (puzzolane) in their cement/beton. That's what gave the strength and durability for their constructions. Nice job.

[@PaddysBushcraft]

They done something different cause mine was not strong 😔 I here the use salt water also

[@formallydehyde]

The ratio of quicklime was like 1 part quicklime to 2 or 3 parts pozzolana (presumably by volume?) depending on if the structure was underwater or not, according to the wiki article. So there might not be enough lime here. Not sure what the typical ratio for normal cement is. Some other side notes: I think they used something called "tuff" as aggregate, which is basically a type of pumice so it's really porous and lightweight. In more urban dwellings they sometimes used broken pottery shards as aggregate, which is kind of cool looking. Also for longevity you can't reinforce concrete that's mixed with seawater using iron or steel because the salt will rust it badly, and that tends to mess up the surrounding concrete because iron expands as it rusts. Essentially the same thing that happens to steel reinforced concrete on salted roads or that contact the sea.
