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?

    I’ll give that a try. Why do you mean that they are meant to break? They have lasted for 60 years now, that’s not too bad.

      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.
