Crushed stone is called material with the property of fever, granular shape and naganic origin. Receive it in the process of crushing stones or metal processing. In fact, crushed stone is just small waste. Dimensions or fractions of crushed stone vary depending on the tasks of it assigned. Fractions can be standard, t. e. such as he is defined by a person, and non -standard. Two more ways to classify crushed stone is the plane of bream and frost resistance. And finally, crushed stone in Tula with delivery can be used either for construction work, or for road.
By type, crushed stone is divided into slag, granite, limestone, gravel, secondary. Granite crushed stone is obtained from granite and it is considered the most durable of all. Such gravel is usually filled with concrete to increase the strength of the foundation, also finish the facades or use for decorative work. There is such an opportunity due to the fact that gravel of granite has a multi -colored texture and glossy surface.
Gravel crushed stone is obtained after the rocky rocks are sifted. In strength, he loses to granite, but it is cheaper and the background of radioactivity is reduced.
After the crushing of limestone, limestone crushed stone is obtained. Its composition contains calcite, and this allows you to successfully use it in the production of reinforced concrete products or on road construction.
Secondary crushed stone is a derivative of the processing and crushing of construction waste from the residues of bricks, concrete, asphalt. It is the cheapest of all and also reduces the cost of concrete to which it is added. In the parameters of strength and frost resistance, he loses to other crushed stone, but it is successfully used to decorate the territory or as fixing for the soil. Sklakock is waste of the production forces of metallurgy.
