Water Content - Moisture Content - Soil Mechanics - Civil …
Water content or moisture content is the quantity of water contained in a material, such as soil (called soil moisture), rock, ceramics, crops, or wood. Water content is used in a wide range of scientific and technical areas, and is expressed as a ratio, which can range from 0 (completely dry) to the value of the … See more Volumetric water content, θ, is defined mathematically as: $${\displaystyle \theta ={\frac {V_{w}}{V_{\text{wet}}}}}$$ where $${\displaystyle V_{w}}$$ is the volume of water and See more Direct methods Water content can be directly measured using a drying oven. Gravimetric water content, u, is calculated via the mass of water See more Generally, an aggregate has four different moisture conditions. They are Oven-dry (OD), Air-dry (AD), Saturated surface dry (SSD) and damp (or wet). Oven-dry and Saturated surface … See more • Robinson, David A.
