[TowerTalk] Slump testing?

[J.P. Kleinhaus]

Greetings:

I am scheduled to pour concrete for my (long awaited) tower
project on Friday.  I ordered 5000 PSI mix, but realize that
short of performing a slump test on site, I have no way of knowing
if the stuff being delivered will be up to spec.

Any hints on doing this?  Has anyone actually done this before,
or should I assume that since I ordered 500 PSI, I should end
up with at least 4000 PSI ? :-)
