Re: Concrete floors ...revisited!
I think you have enough info on concrete but I didn't understand the one person's negative comment re a vapor barrier. In upstate NY good contractors put plastic sheeting down beofre the concrete is poured, not as a vapor barrier after the concrete cured but to ****** the curing process and prevent the moisture from leaching out as the concrete cures. For normal concrete (there are special mixes this doesn't apply to) the longer it takes to cure the harder it cures. The stronget concrete can be poured under water totally and will cure just fine) this is most important if you pour under hot dry conditions. in that case you want to water the concrete as it cures. I know one guy who poured his basement, plugged the drain and flooded it for a week as it cured! I know they used plastic sheeting under the floors at the Anheuser-Bush plant up here and those floors were 12 inches thick. I have to assume they know what they're doing!
