RE: Minimum Slab on Grade Steel

I don't believe that there is an accepted minimum reinforcing ratio for slabs on grade.  I have occasionally designed industrial slabs with no (zero, nil, nada) reinforcement and had good success.  Of course, this requires frequent jointing and excellent curing.

Subject: Minimum Slab on Grade Steel

It has always been my opinion that ACI 7.12.2.1 (0.0018 minimum temperature and shrinkage reinforcing) applies to elevated slabs and not slabs on grade.  I have always designed my sog reinforcing to ACI 7.12.2.1.
 
Is there a code or industry recommendation for sog minimum steel?  I find myself in a situation where a contractor has made an error and I am trying to substantiate my design/specification with code/industry reference while the contractor tries to politely challenge me.
 
Thanks in advance for your prompt response.
