I've mixed concrete before, but only as a labourer or kid when I had someone who knew what they were doing to say "more of this/that" or just "that looks about right".
I mixed tons of concrete for my dad as a teenager when we built a garage and concreted the driveway to it. His mate came to help once and mixed the concrete that day, the stuff he mixed degraded far quicker than the stuff I mixed. As @Colin_the_Bald says, getting the consistency right is key.
