RE: Acidic Soil

You can formulate a concrete mix that would resist some measure of acid, but
a barrier is more of a sure thing.  A barrier is what is used commonly in
areas like Saudia Arabia for sulfate resistance.

I would suggest:
1.  Place a heavy membrane (similar to a T-Lock) on grade
2.  Place the rebar
3.  Form the sides of the foundations
4.  Place the concrete
5.  Strip the forms
6.  Apply a liquid membrane (a polyeurethane) on all vertical and exposed
horizontal surfaces to be in contact with the soil
