sandsized

Sandsized is an informal descriptor used to characterize materials whose particle size lies in the range commonly assigned to sand. In geology, soil science, and related disciplines, sand is defined as particles larger than silt and clay but smaller than gravel, with sandsized materials typically described as having a substantial portion of grains between about 0.0625 millimeters and 2 millimeters in diameter. Because sandsized is not a formal grade within official classification systems, its precise meaning can vary by context, region, and industry.

The term is often applied to bulk materials, substrates, or soils to indicate behavior typical of sand, such as relatively good drainage, moderate to high porosity, and limited cohesion compared with finer textures. Sandsized materials may be used to adjust texture in soil mixes, to create drainage layers, or to influence filtration and compaction properties in engineering projects.

Applications of sandsized materials span several fields. In construction and civil engineering, they can serve as fine aggregates or sub-base components. In horticulture and agriculture, sandsized substrates improve aeration and water movement around roots. In water treatment and aquaculture, sandsized media provide surface area for filtration and support biological processes.

Characterization of whether a material is sandsized is usually accomplished through particle-size analysis, such as sieve testing or laser diffraction, to determine the share of grains within the sand range. While commonly referenced in practical contexts, the term remains an informal descriptor rather than a formal taxonomic category.
