Concrete mix recommendation for filling out slab voids

Door framing was embedded into the slab and rotted out.

Thank you!

Get rid of the black stuff and any crap out of the void.  Slather the areas that will abutt the new filler with concrete glue.  I'd probably use sand mix, concrete with some small stones......should be available by the name.
