Building a shower corner, where one wall (2 m high, 1.2 m wide, i.e., 10x6 glass blocks) is constructed with glass block concrete. The wall starts against the room wall and ends with a free edge to be covered with an aluminum strip. On the glass block manufacturers' websites (and on the package of glass block mortar), it says to have 5-10 mm of foam in the vertical joint between the fixed wall and the glass blocks. Is it supposed to be like that? I think it seems flimsy; the glass blocks will only be supported by the reinforcing bars and grout in that case. The room is in the basement, with a cast concrete floor slab, and the wall is a load-bearing outer wall. The only movement in that system should be the Earth's rotation, I think.
If you stumble in the shower or lean against the wall, it's good if it doesn't shatter into pieces.
Glass blocks are not something I would really recommend for a shower.
If you absolutely must have them, perhaps an end could be an aluminum U-channel running from wall to ceiling, covering a part of the block.
You could also consider such a channel against the wall so that the wall is essentially free-standing in these profiles. The one against the wall, you simply screw into place all the way.
