Quick-drying concrete

[Radik]

Hello. We are going to renovate the bathroom soon and will then replace the floor drain. The quick-drying concrete I found at the supermarkets only handles down to 80mm. Replacing the floor drain requires more than that. So I wonder if you can simply divide it up. So you do about 80mm then wait until it dries and add the next layer. So you might have to do it 2-3 times.
But is it okay to do so? Is there anything one should consider?

Maxit 319 you have max 100mm op.

If I were you, I would have reinforced so the reinforcement sticks up from the first layer when you are going to put the second one so you have the same reinforcement through both layers, that should be enough!!

Then you can mix the concrete with small/large stones so you don't have to use as much concrete.
