A report on issues at a Texas football stadium has found that cracks in the concrete slabs occurred because of excessive water, a result of re-tempering the initial concrete mixture. Is there ever a time when this practice is appropriate?

It's one thing to add water to keep mortar workable (and only within reason, at that)...but concrete? Absolutely not! You get your one shot with concrete....you load the mix and can make a little adjustment when you get to site...but if your air or slump don't meet spec, get a new batch because once it is placed, it's a heck of a lot harder and far more expensive to remove and replace if you've messed it up. Can you imagine the issues if it weren't floor slabs, but structural columns or beams that they messed up the concrete on?
