I've always been told that to 'specify' a slump is in no way related to moisture results. Heck you can use Lafarge Agila (~100% slump) and still get the same drying characteristics of other concrete.

Slump is how much a column of concrete sags when the casting mold is removed. A 6" slump is quite soupy, and would be very easy to work. Flat concrete is usually spec'd at a 4" slump, but by using water reducers contractors can use only the water required for a 3" slump and still get the consistency of a 5" slump.

Water reducers make the concrete slippery, allowing it to consolidate and flow more readily. These products dissipate rapidly and don't add excess water to the mix.
