You might use the same technique as the cold-storage people. They put sloping pipes below the foundation, and keep the ground from freezing by using outside or heated air constantly circulating below the floor slab. You could use cooling coils in the upper region of the concrete to keep the concrete from getting overheated. Fountain E. Conner, P.E.
