Dolomite rubble
Crushed stone is produced from dolomite, a sedimentary rock. The main component is calcium carbonate, the content of which varies depending on the place of extraction of the stone. Iron hydroxide and clay give it a yellowish tint. And oxides of manganese, barium, and strontium make it bluish-gray. At the break, the surface of the stone is either matte, mother-of-pearl, or glass.
Production begins with the extraction of minerals. It is mined in quarries using the explosive method. The resulting large fragments are loaded into dump trucks and delivered to the processing plant. Here, the stone is crushed in special crushers until the desired particle size is reached, and then sieved through sieves. This is how the grains are divided by size. Additionally, the granules are treated with chemicals to increase their resistance to temperature changes. This significantly increases the service life of products and bases created using such crushed stone.
