Since we are only doing the testing and were not involved with the design, we have to be careful. I do not think we will be on the hook for problems. And we may be over stepping our bounds by officially bring up concerns about the design. We have done it informally, though.

Great comments. Thanks everyone. I had another comment from a concrete person outside this forum that says the differential temperature is the more critical in our situation. He said that we should be OK in the summer with the ambient temp being high, but could have problems in the winter...
We can add thermocouples to measure the temperature. ACI is very general, but they do say the concrete should not rise in temp more than 25 deg F above the mean annual ambient temp for mass pours. That would be about 115 deg. Does anyone have a maximum temperature before problems arise? I...
We are performing materials testing on a 4-ft thick concrete slab pour with 1500 cy. The specifications are loose and the contractor is going to do one continuous pour. The maximum specified placement temp is 95 deg and there are no specific requirements for cooling. The pour will start in...
