I am not a structural engineer just studied architecture, and structure was my favorite subject.
you cannot equate earthbag construction with concrete. its more like adobe. Except it has less structural integraty because the units are divided by plastic bags instead of mortared together.
How old is the oldest earthbag structure? I am not at all convinced of this technique and will never use it. If you decide to use it, at least have some serious builder with structural knowledge look at your design to ensure you don't build something that's going to fall on your family's heads, please. especially domes !
here is a definition of monolithic:
1. formed of a single large block of stone
(this post is in response to all the recommendations to use earth bag construction instead of a monolithic concrete dome)
