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]
A typical modern lime mortar mix would be 1 part lime putty to 3 parts washed, well graded, sharp sand. Other materials have been used as aggregate instead of sand. The theory is that the voids of empty space between the sand particles account for 1/3 of the volume of the sand.
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.
Louis H. Bolander, the assistant librarian at the Naval Academy, wrote an article on Wickes in 1928, entitled "A Forgotten Hero of the American Revolution."Appearing in Americana, in April 1928, the article closed with a fitting epitaph for Capt.

Children play in a communal sandbox Sandpit with toy tools used by children to play in sand. A sandpit (most Commonwealth countries) or sandbox (US and Canada) is a low, wide container or shallow depression filled with soft (beach) sand in which children can play. Sharp sand (as used in the building industry) is not suitable for such use.
