Crushed stone
Crushed stone (colloquially, crushed stone) is an inorganic, uncoated, loose material with grains from 1 to 10 centimeters in diameter. It is formed in natural conditions by the natural fragmentation (for example, weathering) of larger fragments. It is artificially obtained by crushing coarse-grained rocks.

Depending on the size of the grains, the crushed stone is divided into fractions.:

Crushed stone fractions 3 to 8 and 5 to 20 are used for the production of concrete and products made from it. Fractions 20 to 40 are most often used during the laying of foundations of buildings (as part of the "cushion"), while fractions 25 to 60 and 40 to 70 are used in road construction.

Granite
Limestone
Lime is dirty
Limestone crushed stone (sometimes also called limestone or dolomite crushed stone) is one of the main types of crushed stone, which, in addition to gravel and granite crushed stone, is used in road construction, as well as in the manufacture of reinforced concrete products. It is also allowed to use it when installing drains, provided that it has a sufficiently dense structure. Limestone crushed stone is significantly cheaper than granite and is more common in our strip.
