Where does all the water go that was in the wet concrete mix bert? Its released into to the air, in Mikes case into the dome, which was my point of my post. And this lessens over time as the cured concrete dries.
Its true that concrete keeping concrete wet will make it stronger, also water can be helpful in cooling the concrete in Higher temperatures, where the exothermic reaction heats the concrete as it hardens.
I have seen the effect of condensation first hand in building where the concrete is still 'green' ie not fully cured. Even with sisalation and other methods of condensation control, ends up raining inside every morning as the concrete releases moisture. This effect leesens over the next few weeks.
