Concrete and plaster mix

[Miina8]

hello! A question about the materials concrete and plaster mortar. Can these be mixed with each other?
I'm not going to build with it but make lighter pots in a material that is not as heavy/coarse as only concrete but still durable.
Or are there perhaps better materials?

Render and concrete weigh almost the same; it's the aggregate that makes the weight. Cement mix A is a slightly finer blend but still strong.

When making hypertufa pots, you can mix in perlite instead of sand to reduce the weight. Perhaps that's something to consider?

Render and concrete basically weigh the same, it's the ballast that adds the weight. Cementbruk A is a slightly finer mix but still strong.

Okay, I didn't know that
Thanks, I'll check out cemetbruk A

When making pots out of hypertufa, you can mix in perlite instead of sand to reduce the weight. Might that be something?

Oh, that's smart, I'll write that down thanks!
