Stretch the concrete

I am planning to build a frame to place a tunnel greenhouse on. The greenhouse is 3x8 meters. I was thinking of building a mold 20x20 cm h/w around it. Would it work to fill this mold with, for example, 16/32 or 32/64 macadam (along with rebar) and vibrate down the concrete, alternatively layering concrete/macadam/vibrating to save work and money?

You feed in stone as you fill. You can fill in as much as you can get in without further ado.
