    I looked it up and an 80 pound bag of concrete needs about 3L of water. That all seems doable.

    Anyone know how long it would take to set?

      Make sure you get fast-setting concrete. It’s the difference between the time being about an hour vs about a day.

      I would expect it to be set enough that you could remove the form after a half hour to an hour
