Crushed stone from the ShchPS dense rocks - the inorganic granular bulk received by crushing of rocks, in passing got overburden and containing breeds or sub-standard waste of the mountain enterprises with the subsequent rassev of products of crushing.

Advantages of such breeds and consequently and the crushed stone received from them, durability, frost resistance, water resistance are. All these qualities are irreplaceable in construction.
This type of crushed stone is the most demanded in road construction, is widely applied at production of the reinforced concrete, used during the filling of the bases of responsible constructions and production of strong reinforced concrete designs.
Crushed stone from dense rocks of small fractions can be used in the decorative purposes.
The Crushed-stone-sand Mix (CSSM) is a construction material of a natural origin which turns out at aeration of rocks or when crushing breed in the industrial way.
ShchPS are applied to the device of coverings, bases and additional layers of foundations of highways and airfields, to strengthening of roadsides of highways.
Quality of crushed stone is defined by a number of its properties: durability, frost resistance, leshchadnost, radioactivity, etc.
Production meets the high quality standards on all key parameters:
1. Durability
Characterizes wear resistance of material at operation.
High rates of resistance of crushed stone to various loadings guarantee durability of pavings.
2. Frost resistance
Ability of rock in the state saturated with water to maintain repeated alternate freezing and thawing. The characteristic of frost resistance of crushed stone is defined in vitro, by crushed stone saturation by solution of sulfate sodium and the subsequent its drying. Actually frost resistance is a limit quantity of cycles of freezing and thawing for each concrete brand of crushed stone.
3. Leshchadnost
Determines degree of planeness of crushed stone in a percentage ratio depending on the content of lamellar and iglovaty grains (grain by thickness or width more than 3 times smaller than their length).
The content of inclusions of such form is lower, the laying gives big ramming and that it is stronger.
4. Radioactivity
Activity of natural radionuclides which is defined after establishment of a radiation and hygienic assessment of soil from the place of production and is confirmed by the corresponding certificates, the conclusions.
Crushed stone of the I class of radioactivity (less 370bk/kg) is suitable for any kinds of construction works, such crushed stone is radiation not dangerous.
The crushed stone made by the enterprises of LLC EvrazHolding is high-strength (M1200, M1400), possesses good indicators of frost resistance (F300), a leshchadnost (I, II group) and belongs to the I class of radioactivity.
Other goods: cement, slate, slag stones, plates, brick, electrodes, crushed stone.
