The vendor says the concrete must have room to expand.
This sounds exactly like what you don't have with a
tower base poured in undisturbed earth.  Your concrete
has no rebar, but in the general case with rebar, this
magic stuff would certainly help, but it is unclear
how you would get the broken pieces (still attached by
rebar) out of the hole.  Even without rebar, I don't
see how you get a hold of the pieces to lift them out.
Good luck.
