Tents are great if you can keep it heated all day and night, frozen ground sets you up for failure. There are a number of companies that offer heating systems that will defrost frozen ground. They use a liquid heater and tubes, and insulated blankets, that will thaw out the ground or prevent it from freezing. With concrete you have to remember to keep it from freezing during the curing time, this varies with the type of concrete and pour temperature. 35 and rising not too much trouble, 32 and falling watch for the edges to freeze first. If you have a heater and tents with the ground thawed out you should be ok as long as you pour early in the day and keep it heated or insulated or both depending on the temps.
If your doing pavers, and your base is installed with no frost in the ground your ok, you can heat your sand dumped over 12" CMP pipe with a couple of propane torches inside. Keep it warm until you compact and your set to go.
