The very first one mentioned one of reasons right off the bat that I listed in the previous post.

"We try to pour and place and finish concrete when it's below 90 degrees," says Daniel Ward, the construction company's project director.
From inside an air-conditioned trailer, he says there are things you can do to modify the concrete, like adding ice to cool it down. But it's just best to work when it's not as hot.
There are two reasons for working such strange hours. One is the concrete itself.
"It sets up too quick in the day with the sun on it," says general superintendent Mike Wigness. "Here it's a little bit slower and manageable."
The other reason is making sure the workers don't overheat.
"Everything out here is metal," Wigness says. "I mean, the rebar, a lot of the forms — it gets hot. I mean, it burns your hands."

Not only do the metal forms and rebar get hot from the sunlight, the cement truck mixer drum which is made of steel also transfers heat into the mix. Lots and lots of heat.
Nobody wants to fail inspection and or testing. Then have to do it over again.
Phoenix is a extreme example and not indicative of most places.
Nice try though...
