Fine particles collected from sand are known as bistay  or vibro sand. It’s typically used to give a wall a final touch of cement.

Sand is a granular material made up of rock and mineral particles that have been finely split. The composition of sand varies, but it is determined by the size of its grains. Grains of sand are smaller and coarser than those of gravel and silt. Sand can also refer to a soil type or a textural class of soil, i.e., a soil with more than 85% sand-sized particles by mass.

Sand’s composition varies depending on the rock sources and conditions, although silica (silicon dioxide, or SiO2), usually in the form of quartz, is the most prevalent ingredient of sand in inland continental and non-tropical coastal environments.

Sand has a variety of definitions. Sand is defined by the scientific Unified Soil Classification System, which corresponds to US Standard Sieves, as having a diameter of between 0.074 and 4.75 millimeters. By another definition, sand particles range in diameter from 0.0625 mm (or 16 mm), which has a volume of about 0.00012 cubic millimeters, to 2 mm, which has a volume of about 4.2 cubic millimeters, the difference in volumes being in terms of diameter.

A sand grain is any particle that falls between this range of sizes. Sand grains are in between gravel grains (the latter system has particles ranging from 2 to 64 mm in size, and the former system has particles ranging from 4.75 to 75 mm in size).

For more than a century, the size distinction between sand and gravel has remained consistent, however under the Albert Atterberg standard in use in the early twentieth century, particle diameters as small as 0.02 mm were classified sand.

The diameter of the sand grains in Archimedes’ The Sand Reckoner, written circa 240 BCE, was 0.02 mm. The Department of Agriculture of the United States set a limit of 0.05 mm in 1938. The American Association of State Highway and Transportation Officials produced an engineering standard in 1953 that stated that the minimum sand size should be 0.074 mm. When rubbed between the fingertips, sand seems grittier. Silt, on the other hand, has a flour-like odor.
