    What indicators tell you when the limestone is not fully cooked?
    How long did you initially cook it for?
    What consistency temperature?

    • @PaddysBushcraft

      Cook for approx 1.5 hrs
      When you put it into water it starts to slake (deslove) only the outer layer desloved I could not get it hot enough to cook through ..I can't get pine to burn hot enough need a hard wood like oak or maybe charcoal

    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

    Awesome Content!🎉
    1. Can xpats buy land in Ireland?
    2. Where’d you get your pants and does it clean out well?
    3. What parts per ingredient did you use for the kiln?
    4. Isn’t limestone corrosive to bare skin?

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

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

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

      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?

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

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

      They air dry it takes a few days

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

      They did. This man just created basically a plaster soluable in water not a concrete. Roman concrete has a complex reaction and need correct ingridients not just limestone.

    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
      @PaddysBushcraft  ปีที่แล้ว +1

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

    • @formallydehyde
      @formallydehyde ปีที่แล้ว

      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.
