concrete

amount of water that's added to the mix. The rest evaporates if it's outside - if it's inside, it condenses on surfaces like walls and ceilings.

You'll always have some moisture in the atmosphere. Local peaks can occur from diffusion up through concrete- concrete is quite permeable. Was a moisture barrier put in place under the concrete?

I'm assuming your concrete was just poured and is curing? One of the byproducts of curing concrete, both due to evaporation and the chemical process itself, is water usually in the form of vapor. This then condenses on any colder surfaces (windows, walls, etc...). So assuming your concrete is in a curing state, this should be normal. If this is concrete that has been down for a while, you may have other issues. Cheers, cc

May can try sealing it once completely cured and dry, may have to remove the moisture from the room with a de-humidifier to allow to dry out.
