SAND - The friable sedimentary rock consisting of grains of quartz, field pshat and small particles of other firm minerals.

River sand is the construction sand extracted from the bed of the rivers, differing in high extent of cleaning and lack of foreign inclusions, clay impurity and stones.

According to GOST 8736 - 93 construction sand is the inorganic bulk with fineness of grains to 5 mm formed as a result of natural destruction of rocky rocks and received when developing sandy and sand - gravel fields without use or with use of the special concentrating equipment.

It is widely used as a part of construction materials, for a namyvka of sites under construction, for sandblasting, at construction of roads, embankments, in housing construction for backfilling, at improvement of domestic territories, by production of solution for a laying, plaster and base works, used for concrete production, in road construction. By production of reinforced concrete products, concrete of high brands of durability, and also by production of paving slabs, borders, well rings use coarse - grained sand (Mk 2, 2 — 2, 5). Small construction sand is used for preparation of nakryvochny solutions. Besides sand is the main component at glass production.

Construction river sand is quite widely applicable in various decorative (mix with various dyes for receiving special structural coverings) and finishing works of the ready room. He also acts as a component of asphalt concrete mixes which are used in construction and laying of roads (including for construction of airfields), and also in processes of filtering and water purification.

In the nature there are so - called black sand which are found in the most various corners of the globe. They consist of dark - colored heavy minerals and are formed as a result of washing away of easier and light minerals. Most often their main minerals are hematite, ilmenite, magnetite. Such sand often form loose fields. For 1981 in black sand 50 minerals from 8 thousand known at that time, and also a set of rare - earth elements were found.

In some coastal areas of the globe, for example, on beaches of India, Brazil, Ukraine — on the northern coast of the Sea of Azov radioactive black sand meet. Radioactivity of such sand in Priazovye on average — from fifty to three hundred microroentgen an hour, but in certain cases can reach 1000 microroentgen an hour. Their main weight is made by not radioactive ilmenite (it contains the titan), however the main part of radiation proceeds from the monocyte which is contained in them. Black sand of Priazovye also often obogashchyona rare - earth elements. Such sand are formed as a result of natural geological processes and right after emergence have black color and shine like metals. According to researches of the MSU Azov research station, in Priazovye the most radioactive of such sand are located around the bases of braids between Mariupol and Berdyansk.
