Regardless of the eventual load, it still has to cure (lots of details here: http://www.cement.org/for-concrete-books...nstruction). And curing in sub-zero temperatures is not so effective, so need to use heaters and tarps to keep the concrete warm.
they are doing that right now with the tracks at fairview mall.
