Concrete In-Situ Relative Humidity Testing - Friend or Foe?
The link below will display a "White Paper" focused on the use and/or misuse of Concrete In-Situ Relative Humidity test results and data. The intent of this paper is not to disparage the use of in-situ RH testing, but rather to encourage more comprehensive evaluation of concrete floor slabs intended to host floor covering or coating systems. Concrete floor slab evaluation needs to be more comprehensive than typically performed, including, but not limited to, the collection of In-situ Relative Humidity test data.
The link below will display an article co-authored by George Donnelly and Peter Craig that was published in the September 2006 issue of Concrete International
The subject deals with testing concrete dryness and the ways that calcium chloride tests may offer misleading results.
