Concrete Hood Method

RE: Concrete Hood Method
CaCl dome tests will stabilize humidity to between 20-40% dependent upon the ambient temperatures..within the protocol in ASTM F1869...the humidity under the dome attempts to stabilize at 40%, so any moisture content past 40% as free water WILL get absorbed.

No matter what kind of R.H. is used, unless the VOLUME of pore space is known...the volume of water is unknowable. The relative humidity change dramatically with temperature..even if the volume of water does NOT change...so a floor with a "safe" level within the temperature parameters set within the stated standard of F1869...could have a safe r.h. of 65% at 80oF but show over 95% r.h. at 65 degrees..even if the VOLUME of water remains unchanged.
