You might as well ask why the sun rises and sets.

Concrete cracks, its a fact of life. That's why roads that are paved with it aren't one continuous road, they're a bunch of panels.

The difference in the time it takes can be based on many factors (quality of mix, placement method, even the weather when it was placed). The point is, just because the concrete cracks, it doesn't mean its a bad mix.
