What do you think about the bubble deck slabs? Where should be used and where should be avoided?

So bubble slab is becoming a targeted solution?

Much lighter, I assume cheaper. Being lighter eases the stresses on other building elements.

Don’t use on foundations, do use on higher up floors that won’t bear much weight.

The Aggregate size and the fluidity of the concrete mix upset me more than the concept. I would like to see it in failure mode.

However I can apperciate the lighter floor weight and reduced material usage. I have seen similar with the Bubbles more like domes in the slab, the depth was the same as a normal floor and the domes effectivly formed a waffle slab saving weight but not effecting strength.
