ACI Committee 436 "Suggested Design Procedures for Combined Footings", "ACI Journal Proceedings", Vol 63, No. 10, October 1966, pp1041-1058
check ACI 10.5.3 and 7.12.2 for min steel reinforcement

Less than 0.15% is a bit mean and might lead to problems as far as crack control goes.
Thick slabs can be designed using the "marzipan" technique to cut down on % but you need to know what you are doing for that.
Hope that helps.

Could you please be more specific on the meaning of 'marzipan' technique?
Thanks
