ᐅ Building Stair Railings with Aerated Concrete Blocks – Is It Stable?

I have a question... Our construction manager wants to build a railing on our 1.07m (3.5 ft) wide concrete staircase using 7cm (2.75 inches) Ytong blocks and then plaster it...
From the beginning, we wanted a masonry railing, but now the stairwell opening is quite large, so a full wall from top to bottom across the two floors is no longer possible...
But will something like this hold? Has anyone done this before?

The joint is rather brittle (in the sense of "not tough"), and especially at the base, it can break relatively easily if there is a sudden impact load on the railing.That is fundamentally correct. It depends on whether the adhesive was applied properly and on the stair construction. With a landing staircase, there is an interlocking structure that better absorbs lateral forces. For a straight staircase, I would be more critical.
A structural engineer would probably not approve such a construction. In practice, after plastering, I don’t see any problems as long as a 100kg (220 lbs) bowling ball doesn’t crash into it with full force.
