Description of activity
The crushed-stone plant located in the Aktyubinsk region, Aytekebinsky district, the item. Komsomol
Crushed stone — inorganic, granular, the bulk with grains fineness over 5 mm (according to the European standards - more than 3 mm) received drobleniyemgorny breeds, gravel and boulders, in passing got overburden and containing breeds or sub-standard waste of the mountain enterprises for processing of ores (ferrous, non-ferrous and rare metals of metallurgical industry) and nonmetallic fossil other industries and the subsequent rassev of products of crushing
Grains of crushed stone have various form, depending on a leshchadnost. A surface their rough therefore they are well linked to cement and sand solution in the course of concrete production.
Crushed stone of fraction 3-8 and 5-20 is used for production of concrete and products from it. The fraction 20-40 is applied most often during laying of the bases of buildings (as part of "pillow"), and fractions 25-60 and 40-70 are used in road construction.
Crushed stone of fraction 25-60 can be used only for a ballast sloyazheleznodorozhny way (GOST 7392-2002). In construction, according to GOST 8267-93, other fractions of crushed stone are used.
Fractions of crushed stone
Granite crushed stone
Granite crushed stone is a crushed stone from solid rock of a granular structure which is the most widespread on Earth. Granitnayaskala represents the magma which stiffened at big depths. Consisting of well created crystals of feldspar, quartz, mica, etc. Also red, pink or gray, put in order from prevalence in it of spar and mica has color. Blocks receive usually by explosion of the monolithic rock, then they are split up in the car, and the received crushed stone is sifted on fractions. It is the last production phase of crushed stone.0-5 mm (granite elimination) — the smallest fraction of granite crushed stone, in strict understanding - do not belong to crushed stone, and is a by-product at its production. It is applied as decorative material to finishing, and also to an otsypaniye of paths and roads, nurseries and sports grounds; for production of concrete products, in particular with a surface of "the washed concrete";
5-10 mm — the smallest fraction from commercially available. It is used in production of concrete and designs from it for optimization of fractional composition of large filler, for example in production of plates of overlapping in the bezopalubochny way;
5-20 mm (mix of fractions 5-10 and 10-20) - are in the greatest demand. It is used in production of concrete and designs from it, in base works, when filling mostovykhkonstruktion, a bridge cloth, road and airfield coverings of the bases;
20-40 mm — average fraction. It is applied in production of concrete, reinforced concrete designs, in construction of highways and railroads, tram lines, at laying of the base and construction of production buildings;
20-70 mm, 40-70 mm — large fraction, are used in production of concrete, massive designs from it and for works with large volume of concrete. It is applied also in road construction within settlements, at construction of production buildings and constructions;
70-120 mm, 120-150 mm, 150-300 mm (QUARRYSTONE) — are seldom used. It is applied in the decorative purposes, usually to finishing of fences, reservoirs, pools.
