Jon, did you use that cement over a foam base? One thing I like about the ShapeCrete is that it contains fine fibers that make it quite strong. After 3 or 4 days of curing even 1/8 inch thickness is easily handled without breaking.

No Win, I poured into open forms. Each arch on the curved section was done one at a time. Rain gutter nails were used as rebar to hold them together.
I didn't do any thickness tests. Cement All has an additive to reduce water during casting.
It did suffer one cracked leg when a trailer was backed into the layout and it's section hit the ground. Otherwise it sits fine. I admit it's a tad crude, I had a vision for the curved arches, then I needed a use!
I mixed stucco color into the dry cement for a uniform tint.

I wonder if you mixed to clay like consistency, if you could push sheets of it, firmly into the mold, with a rolling action to eliminate the bubbles ...
