When we started pouring the concrete at 7 am, the temperature was 15 degrees F. At 3:30 pm the temperature was only 30 degrees F. How did the concrete set-up in freezing cold temperatures? We use a 4000 psi concrete mix with 160 degree hot water mixed into it. Then we add an accelerator to boost the drying time. Sometimes this formula works really good, but if you're pouring on a sub-base that's extremely cold your concrete will cool down very fast and not set-up like you would expect it to. We never pour concrete on a frozen sub-base. If you do, the sub-base will settle and your concrete will have un-even areas as the hot concrete starts defrosting the sub-base. Always protect your sub-base from freezing, you can use insulating blankets like we do or you can use plastic and hay or straw. Then, after finishing the concrete, protect the concrete with the same insulating blankets or hay. Keep the concrete from freezing until it reaches 500 psi or at least 2 full days after the pour.
