What is crushed stone? This is just a mixture of angular fragments of stone, completely different configurations, about five to one hundred and fifty millimeters in size. They receive it by crushing rocks, such as, for example: diabase, granite and other waterproof, dense, sedimentary rocks (dolomite, limestone, sandstone), and also metamorphic rocks.
Most of all is the demand of crushed stone from solid breeds, which has a fairly high strength and frost resistance. In the event that crushed stone is used for road construction, it must be borne in mind that there is high resistance to impact and abrasion.
Brushing stone is required almost everywhere in construction, buying crushed stone is not difficult now. There are many companies that are engaged in the development and provision of this material.
Crushed stone can be divided into stamps by the limit of the strength. Real crushed stone must consist of homogeneous in the quality of the breeds of the breed. This is a fairly important requirement, it is completely impossible to allow crushed stone to be used during construction, which is obtained from fragments of completely different breeds.
This is understandable. Crushed stone exist, for example, hard, resistant to abrasion and it suddenly gets soft and easily blurred, which, accordingly, will fall apart instantly, as soon as a fairly large load begins to act on it.
As an example, imagine that in a concrete column there is crushed stone that has its own purpose, respectively, the relevant requirements are imposed on it. For example, crushed stone for road construction, it must have high resistance to abrasion, except that it should have good strength.
Very widely crushed stone are used in construction, mainly in cement-concrete, reinforced concrete details.
