Vapor Drive / Osmotic Action & RH

#3
(10-13-2012, 08:35 PM)CC Solutions Wrote:  The RH of a slab can lead to increased vapor drive, as vapor drive is a function of differential vapor pressures. So a wet slab will release more vapor to dry air, and a dry slab will release less, or I should say release vapor at a slower rate.


I see so high RH = higher vapor but we don't have an accurate test for vapor so our best guess is RH as a predictor. Let's leave Osmosis out of the conversation for now. How do I measure vapor if the science behind the ASTM is no good?

I can see this question happening to me and want to have my answer ready for some day...
