Outside corner + Masterboard

[B6304S1]

Hello!

I am going to build two walls (which will be tiled) for my new shower.

The walls are built on 45x70 studs, and the boards are made of Masterboard.

What should I do with the outside corners? Should I use corner bead, like with drywall?
Or is the Masterboard so much harder that it's not needed?

If you are going to tile, you can get outer corners (plastic) that are attached when you tile.
The masterboard can be plastered in the corners.

Ok!
