Concrete for grout
(OP)
Would you substitute concrete for grout?
The concrete would be a plant mixed f'c=3500 psi mix.
Largest aggregate size would be 1/2" diameter.
I think I need to check code requirements.

The contractor wants to use the footing concrete mix with extra water added at the site after pouring the footings.
I am going to deny the request.
1. the concrete mix has an air entraining admixture
2. no way to control the mix w/c ratio at the site.

These are about 2 or 3" in diameter and about 4 inches long
(I don't know the size exactly)
If not, what are these intended for?

This was kind of a on the fly question.

Mortar, grout, and "concrete" are all concretes with different aggregate and slump ranges.
RE: Concrete for grout
My decision to deny the request has to do with execution in the field. The contractor proposed to use leftover concrete in a truck for grout. The concrete was a 3000 psi mix with 1/2" aggregate and air entrainment admixture among other admixtures. The contractor proposed to add water to whatever unknown amount of concrete and then use as grout.
