Common salt will kill moss.

Hmm...Many years ago I scattered some ordinary cooking salt onto the
concrete path around our previous house to melt ice. The concrete in
those areas then degraded quite seriously over the next few years.

Calcium chloride is water soluble and although sodium chloride is more
soluble the net result is to damage the concrete. High density paving
slabs shouldn't suffer too badly but lower grade ones literally fall
apart. There is a village not far away that used the wrong grade on
their pavements and they are crumbing to dust due to salt action.
