Mapping Out Your RH Test

Mapping Out Your RH Test

By Jason Spangler in RH Testing Concrete Moisture & Rapid RH® | 0 Comment

In situ probes are a key element of relative humidity (RH) testing and of a contractor’s ability to accurately measure concrete slab moisture conditions because of their placement within the concrete slab. Once installed, builders must allow Wagner Meters’ Smart Sensors to equilibrate. But what is the strategy for proper sensor placement and for RH […]

Calibration for RH Testing Made Easy

By Jason Spangler in RH Testing Concrete Moisture & Rapid RH® | 0 Comment

Relative humidity (RH) moisture testing in concrete requires a properly calibrated in situ probe to ensure accuracy. Calibration certainly makes good sense for your own protection in case any moisture-related issues arise in the future. In addition, compliance with ASTM F2170 certainly requires calibration and its accompanying documentation. So any way you look at it […]

New, Eco-Friendly Concrete Shows Promise, but Still Requires Testing

By Jason Spangler in RH Testing Concrete Moisture & Rapid RH® | 0 Comment

In a 2011 global energy report, the World Wildlife Federation (WWF) declared that the concrete industry produces eight percent of the world’s annual carbon dioxide transmissions (primarily in the production process). Yet, production has quadrupled since 1970, and the WWF claims the industry can reduce its carbon footprint by 90 percent. Concrete 101 at Hyper-Speed […]

External Influences on Internal Concrete Moisture Content

By Jason Spangler in Concrete Chemistry Concrete Moisture & Rapid RH® | 3 Comments

There are several external factors that influence the moisture content in concrete. They are: Time Vapor retarders Bond breaking agents Heating, ventilation and air-conditioning (HVAC) Concrete slab construction is an exercise in convergence. Builders apply several methods of facilitating the successful curing, drying, and hydration of concrete slabs. However, those processes and building materials can […]
