Oven-dry (OD) is defined as the condition of an aggregate where there is no moisture within any part of the aggregate. See more 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 … See more Volumetric water content, θ, is defined mathematically as: $${\displaystyle \theta ={\frac {V_{w}}{V_{\text{wet}}}}}$$ where See more Moisture may be present as adsorbed moisture at internal surfaces and as capillary condensed water in small pores. At low relative … See more • Humidity, "water content" in air • Moisture • Viscous fingering • Moisture analysis • Soil moisture sensors 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 $${\displaystyle m_{w}}$$: 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 dry can be achieved by experiments in laboratories, while Air-dry and damp (or wet) … See more • Robinson, David A.
