Is there a way to measure moisture plus cold temperatures sort of like a heat index b

#1
Sad 
I know that heat plus humidity equals the heat index, but is there a cold temperature plus humidity measure. I know the wind chill measurement but is there a way to measure the feels like temp of cold plus humidity.

Wet Bulb?

But I don't know how it relates to concrete floor testing.

Also if you Google "damp cold" there is some talk but not so much a technical definition.

What are ya asking about?

Yes, where are you going with this Ronald?
Heat indexes and wind chills are numbers made up to illustrate the perceived effects of multiple factors such as cold and wind. These perceptions apply to items like people that produce heat or cool themselves. A very dry atmosphere and high heat will cause a person to sweat and that sweat will evaporate readily because the air is dry. The net effect is the air feels cooler than very hot and humid air that does not promote the cooling effect of sweat evaporation.
This effect is only for sweating items.... A rock in 100 degrees and 10% RH with a 50 mph wind is the same temperature as a rock in 100 degrees and 100% Rh with no wind at all, but a person would feel much cooler in the dry air with the breeze.
For concrete RH correlation with temperature, this has not been proven as of yet. We are still working on determining what a 90% RH slab at 60 degrees will be if the slab is warmed to 70 degrees.

there is no index that I am aware of. My experience with moisture testing is when the slab temperature goes down the moisture percedntage increases. Any time the slab temperature is higher than the ambient temperature the moisture will diffuse back into the slab.
