Huh...that’s interesting.  You wouldn’t expect cams to shear out?

Concrete is strongest in compression loading and reasonably strong in shear. It has so little tension capacity that we use a value of "0" for most calculations. I would be surprised if the behavior of stone is very different. Also, use of unreinforced concrete in building applications is pretty rare.
