Measuring Relative Humidity With Embedded BlueRock Sensors In Concrete
During construction, the internal relative humidity (RH) of concrete plays a significant role in the progression of work. Especially in slabs-on-ground or suspended slabs that are to receive moisture-sensitive flooring materials, professionals often rely on experience to understand the drying time of field concrete. Flooring materials such as sheet rubber, epoxy coatings, vinyl composition tile, sheet vinyl, carpet, athletic flooring, laminates, and hardwood can suffer issues such as delamination, blistering, mold growth, and other similar problems due to exposure to moisture and high RH conditions in the concrete (ACI 302.2R-4). Issues like these are responsible for millions of dollars spent on litigation costs per year in affected construction projects. Over the years, the difficulties associated with achieving precise measurements of moisture content in concrete, have been quite a challenge for professionals. The heterogeneous nature of concrete and its physical properties doesn’t…
