I am putting in a 4' X 4' X 6" slab to mount a mail box pedestal. I have the base dug out formed and the rebar in place and covered. We have just experienced a major snow storm and cold snap. How much above freezing will it be safe to mix and pour?

I'm a contractor, you can pore it any temp above 32 degrees. If its going to get real cold toss some hey to cover it, it a insulated blanket. if you get it delivered ask for more chlorine in the mix it will cure faster. good luck man.

By preference, because concrete needs a month to really harden and technically is not considered "set" for up to a year, I'd say if you have the option always plan your concrete work when you have at least a month of above freezing weather. They claim you can add ingredients, use a vibrator to float the water out and keep it covered to prevent frost damage, but everyone I've seen do it has had it crack and scale off at some point. Good luck.

If it doesn't go below freezing at night you should be good with any temp above 40 during the day. Pour early so it has the whole day of sun to cure.

My understanding it must be above freezing untill cured, because if the water in the cement freezes, it expands and creates weaknesses. I suspect wind chill is also a factor. Water doesn't freeze above 32 degrees F.

should be 45-50, but if you really want to pour in the cold, just pour it and then cover with insulation or hay.The concrete Will emit heat while curing and by covering you will retain that heat which in turn will help it cure

Any temperature. If its Quikrete, then it's a chemical reaction that hardens the cement. not temperature. Keeping it wet so it doesn't crack can be tricky, so just above sub-zero.

Quickcrete will set up in all weather however if you are concerned mix in two parts of calcium carbonate and you will have no problems

for mail box.
don't worry..
so small it won't matter.
mix it pour and cover.
do it early in day so it will set.
even if temp drops low it won't hurt that small amount.
