Sharp sand, also known as grit sand or river sand and as builders' sand, concrete sand, or ASTM C33 when medium or coarse grain, is a gritty sand used in concrete and potting soil mixes or to loosen clay soil [1] as well as for building projects. It is not cleaned or smoothed to the extent recreational play sand is. It is useful for drainage. [2]
Such a particle may be a grain of sand, a pebble, cobble or boulder. Although roundness can be numerically quantified, for practical reasons geologists typically use a simple visual chart with up to six categories of roundness: Very angular: corners sharp and jagged; Angular; Sub-angular; Sub-rounded; Rounded; Well-rounded: corners completely ...
Sand is a granular material composed of finely divided mineral particles. Sand has various compositions but is defined by its grain size. Sand grains are smaller than gravel and coarser than silt. Sand can also refer to a textural class of soil or soil type; i.e., a soil containing more than 85 percent sand-sized particles by mass. [2]
Grus is an accumulation of angular, coarse-grained fragments (particles of sand and gravel) resulting from the granular disintegration by the processes of chemical and mechanical weathering of crystalline rocks (most notably granitoids) generally in an arid or semiarid region. [1] Grus sand, when cemented into a sandstone, will form an arkose.
