Concrete Outside Temp

They are not saying it can't be done, just that you need to take precautions (thawed soil, blankets, additives etc.) for it to be done RIGHT.

I've been doing some concrete patching in Northeast Mississippi. When I got down here in early October it was almost too hot, now it's jumped to too cold. But I can wait till March.

I'm sure the OP could pour his pad with all the right stuff at any time of year. But at what cost to do it right? Or would he be better off if he waited till spring?

There is a whole science built around concrete. ACI and the Army Corps of Engineers have been studying and experimenting with concrete mix deigns and ancillary methods since their inception. The USACE Experimental Station in Vicksburg is a fascinating place. I took a 2 week course on concrete inspection there when I was a Construction QA Specialist for the US Navy. There are many books written on the subject over the years. Most structural concrete today is totally unrecognizable from concrete cast 20-30-50 years ago. Constantly evolving. Unfortunately there are no new dams being built of the magnitude of the past. In my 65 year construction related career I have seen my share of success and failures. Most failures are due to improper methodology and refusal to embrace current technology.
