Service conditions…what impact do they really have?
The ASTM F2170 standard mandates measuring relative humidity (RH) at service conditions. But your project’s timeline may be such that you’d like to be able to estimate RH before reaching service conditions.
Unfortunately, especially in new construction environments, the required service conditions don’t exist early on.
Wouldn’t it be great to have a tool that allows you to estimate the RH in the concrete slab once service conditions are met, and to be able to do this quickly and easily?
Wagner Meters is proud to share the Service Temperature Adjustment Chart shown below. It’s a valuable science-based, estimation tool developed by CTLGroup, a wholly-owned subsidiary of the Portland Cement Association.
This table is quite simple to use, once you’ve obtained the RH and temperature readings of your concrete slab using your Rapid RH® kit.
Learn more by clicking on the video, then download the table and start putting this helpful tool to use.
Now you’ll be more confident about making decisions related to concrete moisture, even before you’ve reached service conditions.
