INERT MATERIALS

Inorganic loose stone material in the form of grains larger than 4 mm, obtained by crushing and sieving products of crushing rocks, gravel and boulders, as well as incidentally extracted rocks or substandard waste from mining enterprises processing ores and non-metallic minerals of other industries.

Inorganic loose natural stone material consisting of rounded grains larger than 4 mm.

Rocks formed as a result of the solidification of molten magma in the bowels of the earth or on its surface

Rocks formed from igneous or sedimentary rocks under the influence of geological factors (high temperature, pressure, chemical processes)

Rocks formed as a result of the destruction and weathering of igneous rocks, deposition of mineral substances from aqueous solutions, or deposition, accumulation, and compaction of waste products of plant and animal organisms

The amount of crushed stone or gravel from rocks produced during the day and/or shipped to one consumer during the day, but not more than 5,000 tons.

The mass determined by the results of successive weighing operations after drying at a temperature of (110 ±5)°C at regular intervals, but not less than 1 hour, which varies by no more than 0.1%.

Designation of the size of crushed stone or gravel grains passing through the larger of the two selected sieves and remaining on the smaller screen

Foreign bodies of organic and inorganic origin contained in crushed stone (gravel)

Natural inorganic bulk material with a grain size of up to 5 mm, formed as a result of the natural destruction of rocky rocks and obtained during the development of boulder-gravel-sand, gravel-sand and sand deposits

Natural inorganic bulk material with a grain size of up to 5 mm, with improved grain composition and a lower content of pulverized and clay particles obtained using special equipment.

Natural inorganic bulk material divided into two or more fractions using special equipment.
