In addition, it is worth noting the environmental friendliness of limestone crushed stone, as it does not contain harmful elements or impurities, as well as its resistance to significant temperature changes. Most often, limestone crushed stone is used in the construction of roads, but much depends on its fraction, that is, the size.
Let's consider the main fractions of limestone crushed stone:
- Small fraction. The size of the pebbles in the small fraction can range from 5 to 20 mm. Most often, this rubble is used in the manufacture of concrete, the production of concrete structures and pouring the foundation;
- The middle fraction. The size of the rubble varies from 20 to 40 mm. Crushed granite is used in the production of concrete and concrete structures, as well as road construction;
- The large faction. Dimensions of stones from 40 to 70 mm. Crushed granite fraction is used quite rarely and most often it is used for the production of massive concrete structures.
It is worth noting that limestone crushed stone is almost inferior to granite in all respects, so it is used only in those cases when the quality of the object under construction does not have much significance. For example, limestone crushed stone is used in the construction of roads with a low transport load.
