Main Features
Fractional composition – the sizes that are acceptable for crushed stone are as follows: 0-5 mm – this is the smallest granite screening used for decorative finishing; from 5 to 20 mm - a small fraction that is used for the production of concrete and concrete structures; from 20 to 40 mm – an average fraction that is used for the production of reinforced concrete structures; from 20 to 70 mm is a large fraction that is used for the production of massive concrete structures; from 70 to 300 mm is rarely used, mainly for decorative decoration of reservoirs and pools.

Strength is the ultimate strength, wear of rock and crushed under compression – the permissible value is 800-1600 kgf/cm2, i.e. crushed stone can be strong and high–strength. Frost resistance – the number of cycles of freezing and thawing of granite rubble is 300-400.

Leshchadnost – crushed stone consists of grains of a lamellar (leshchadny) form by 5-23%.

Adhesion is determined by visual inspection of the material, the darker the color, the higher this indicator is.

Radioactivity is an important characteristic of crushed stone. It is determined by the conclusion of the sanitary and epidemiological service. The radioactivity of crushed granite is not more than 370 Bq/kg

What kind of crushed stone is needed for the foundation
When starting the construction of the foundation of an apartment building, it is necessary to take into account the strength, frost resistance, crushed stone fraction and other characteristics that are directly related to the specifics of the structure. These include the following:
If you plan to build a massive one- or two-storey building with thick walls, the foundation for it must be reliable and strong, and for this you need to choose a strong, durable granite rubble.
If a foundation is being built for light buildings such as a garage, shed, gazebo, fence or veranda, then more affordable limestone rubble will be suitable as the foundation.
But do not forget that it is recommended to place the sealing cushion in two layers of sand and crushed stone, each of which should have a thickness of 300 mm. A layer of sand will reduce vertical loads and reduce the risk of soil precipitation under the weight of the walls of the house. A layer of well-packed granite rubble of 20-40 mm fraction will become a reliable foundation for a strong foundation of the house.

How to choose crushed stone for the road
Granite crushed stone of 20-40 mm and 40-70 mm fractions is suitable for road construction and repair. This type of crushed stone is resistant to adverse weather conditions both at subzero temperatures and during precipitation, it does not lose its properties and is considered one of the most durable materials. For roads with low loads, dolomite or limestone crushed stone is used because its strength is inferior to granite.
The use of high-quality materials ensures a long service life of roads, preventing the appearance of cracks and pits. You will not have to make repairs for many years, which allows you to save a lot in the end.

How much crushed stone is in 1 m3 of concrete
Crushed stone is one of the essential components of concrete. Its use makes it possible to increase the strength and frost resistance of the monolith. The amount of crushed stone required to produce 1 m3 of concrete depends on the characteristics of the material itself – fraction, hardness, strength. For each brand, the indicators of the components per cube are given, which are entered in special tables.
In private construction, when it is not possible to ensure high accuracy while observing proportions, the rule applies: 0.8 cubic meters of gravel or granite are required per cubic meter of concrete. With a standard fraction of 5-20 mm, the bulk density of this material is 1360 kg/m3, in this case the mass is 1088 kg. The remaining components fill the voids between the elements, providing high-quality adhesion.
