When RH is read by sensors placed 40% deep into the slab, builders get a sense of how completely the concrete has dried. HC-3000 Relative Humidity Moisture Meter Kit with BluePeg Sensor. The contractor tested the relative In -situ Relative Humidity Concrete slabs on grade tend to curl up at ... of the surface concrete, or, ... in a slab are those that determine the relative humidity and moisture gradient within the When talking about moisture testing, what does equilibration mean? By measuring relative humidity using the ASTM standard F2170-09, a better view of the actual moisture content of the concrete is more accurately measured , which is not dependent on the concrete mix, thickness of the slab or surface conditions.
