Concrete slabs appear to be solid and hard, but in reality, concrete is moist stuff. It begins as a liquid slurry of water, sand, cement, and aggregate, and even after it hardens, moisture continues to pass out of the concrete …
Most "Concrete" Moisture Meters Only Check Surface Moisture. Concrete slabs often have thicknesses measured in feet, not inches. Moisture meters can only check the moisture near the surface of a concrete slab, which is not sufficient for predicting how the slab will react to having sealant applied or other building materials installed over it.
The moisture content in the grain is a particularly important factor that determines the required particle sizes and energy during grinding because there is a direct relationship between moisture content and the grains' mechanical properties [5–7]. In addition, size reduction can generate a new surface area of a particle which will increase ...
