Hello community, I noticed that this stair step in my european 60ies house was a bit cracked so I broke it off completely. How would you fix this? Some mortar or tile glue? Does it need some kind of rebar?

Those stairs have a bullnose that juts out and the whole thing is made from mortar. Mortar is very strong in compression but weak in tension. So a load on the tip of the stairs will put a large tension load on the top of that bullnose where it meets the stair corner. At some point it will break off.
Makes sense.
