expansion joint. Keep in mind that concrete will try to shrink to the
center of the section of slab. If constrained, it can not shrink to the
center, and it will shrink and form its own joints.
Dead ending a slab control joint will result in a stress riser at the
termination. This will become a point of generation of shrinkage cracks.
