Crushed stone is a granular and bulk material of the inorganic type, the size of large grains included in its composition exceeds 5 mm. You can get it due to crushing gravel, rocks and boulders.
If we consider the crushed stone of limestone, then these are rocks presented in the form of acute -angled debris in size up to 100 mm. They are formed in the process of weathering and are found in the form of poorly cemented or loose clusters.
In addition, this material is considered a product of crushing rocky rocks.
You can buy crushed stone in different numbers. The same criterion underlies the classification of this material in the fraction. By origin of rocks, it is also customary to distinguish:
v limestone, v granite, v gravel.
The basic properties of granite crushed stone are contained in its strength, frost resistance, density, water saturation, water collection, in grain composition and shape.
The last criterion is the main point in the qualification of granite crushed stone for the following groups:
V cube-maximum 15, V improved-15-25, V ordinary-25-25.
The dense packaging is formed due to a mixture of cuboid grains. Needle -shaped and plastic grains increase the intermediary void in the mixture. As for cube -shaped grains, they have more strength than such an analogue of plastic and needle -shaped shape.
If we talk about gravel gravel, then its strength exceeds the same indicator in its analogues. However, its radioactive background below.
As for the composition, this material consists of quartz, mica, sleeper and other breeds, which are constituent elements of solid magma. This fact explains the strength criteria, including resistance to the influence of negative atmospheric influences and temperature fluctuations.
This material in the construction market is represented in different colors: green, gray, pink and even red tint. Such an assortment of shades allowed this material to obtain widespread use in the implementation of finishing work.
Graduate graphic gravel, possibly by crushing the natural material of this type,. Indeed, in the quarry, granite is presented in the form of a monolithic solid cliff, which originally explodes, blocks are formed in the result, which are later crushed due to specialized crushing equipment, after which they are sifted and divided into fractions.
It should be noted that the cost of crushed stone depends on its faction. The smaller this indicator, the more expensive material costs.
In addition, the extraction of granite crushed stone is carried out due to the sifting of the breed. In this raw materials, the content of the plate and needle grains is normalized. The latter include grains with a width and thickness not exceeding the length of more than three times.
As for the use of crushed stone, then in this matter it also depends on the fraction. So, for example, the crushed stone of a small fraction of 5-20 mm is used for the manufacture of concrete and all types of structures used during fundamental work.
Crushed stone with a 20-40mm faction is in greatest demand.
This material is used for the same purpose as the same previous raw materials.
The largest fraction is considered crushed stone 40-70 mm. This material has been widely used in the process of manufacturing concrete, large fertiles, and in the performance of various works with a large volume of concrete.
The most scarce material is boot. These large fractions are used to perform decorative work, decoration of pools, water bodies and even river coasts. Also, granite crushed stone is used for fundamental work, in the repair of road surfaces and the manufacture of reinforced concrete.
