The difference is only in the type rock used and how it is finished. Plain concrete can use crushed stone or washed river rock.  In the latter case, as a last step, if you wash the "floated" concrete off and expose the rock, you have exposed aggregate concrete. 
There is another product used for patios that uses epoxy as the binder. It will not work for a foundation and is much more expensive.

Sounds like a question for the cement plant.
