We could almost always get a slab dry in 4 months by using a 3 day wet cure and keeping additional water off it. We left the surface porous and breathable.
I bet you will see a marked difference in RH on your test slabs CCR.
No it does not. There was a communication breakdown somewhere between GC, concrete contractor and who knows who else. About 60% has 6 mil, rest is 15. I am definitely anticipating lower RH in the open profile slab. It was left rough and lower to accommodate thin set and ceramic. I am anticipating also they will need to install a mitigation product to help fend off future issues where the 6 mil was used, as well as the super tight finish of those surface areas. I expect the concrete contractor will be biting the bullet on that expense.
