Concrete and freezing temperatures
Concrete and freezing temperatures
(OP)
For three nights the temperatures under the contractors curing blankets fell below 32 degrees on several tilt wall panels. The total width of the tiltwall panel is 11" however this occurred on the exterior side which is 3" in thickness. A 3"insulation board was placed over the concrete placement except for 6" around the perimeter. The temperature monitoring device was placed within this 6"space to get the reading at the edge. The device was suspended 1 1/2" off the concrete placement to get a reading of the surrounding area. It was recorded at 29 degrees for about two hours each night and below 50 for about 12 hours each day. Does anyone know what is the likelihood of having a problem or what would be an early indication that something is likely to happen later?

If the concrete had frozen in a low strength state, you would already see evidence.

Like others have said, DO NOT LIFT these panels until you know you're good to go.
I'm guessing your Contractor is not going to be pleased about the delay. Don't let their problem become your problem.
