Today, in construction, private and industrial, gravel and crushed stone are quite common, the difference between these two materials can be seen only if we consider the features of each. The use of rocks and minerals in construction manipulations is simply irreplaceable. Despite the fact that the described materials have the same origin, they have a lot of differences. Among other things, looking at them, you can immediately notice the visual difference. With a deeper study of the issue, one cannot fail to note the area of \u200b\u200buse.
Gravel Features
If you have a desire to understand the properties and characteristics of a natural material, then you can delve into its origin. This option is a rock that is formed by a sedimentary method. The gravel is quite friable, and also has interspersed minerals from hard destroyed elements. Three varieties can be distinguished, among them: fine-grained, medium, and also large material. The first variety has elements whose size varies from 1 to 1.25millimeters. Medium-sized stones do not exceed 5 millimeters, as for large inclusions, their dimensions are 10 millimeters. Considering gravel and crushed stone, the differences of which will be described in the article, it is worth highlighting the first type, which may have a different nature of origin. Thus, there is lake, mountain, sea, glacial, and also river material.
Use area
If there is a need to provide the most impressive grip during the construction process, then you should prefer a mountain mineral, while river and sea have a smoother surface. This is due to all kinds of impurities by the type of soil, sand, etc. These features indicate that the mountain variety is most often used during construction work. It is used during the construction of roads, as a filler, for backfilling sites, as well as when mixing concrete mortar to form a foundation. If you decide to consider gravel and crushed stone (differences), you can find photos of these materials in the article.
Varieties
On sale you can find gravel of various colors, it can be brown, pink, yellow or blue. This characteristic made it possible to find the use of this mineral for decorative purposes. If necessary, it can be used to equip landscape gardening areas.
Features of crushed stone
It differs from the above material primarily in external characteristics. SoThus, crushed stone has a rougher surface, in addition, it has sharp corners. The dimensions of this material most often exceed the dimensions of the gravel. It is mined by crushing limestone, granite and boulders. Natural roughness promotes good adhesion to surfaces and other materials. This expands the possibilities of the mineral in practice. If you are considering gravel and crushed gravel, the differences between these materials are described in the article. The dimensions of the latter determine the scope. If the elements do not exceed 5 millimeters, then it is used in the formation of sites, roads, and also for protection against ice.
With sizes ranging from 5 to 10 millimeters, the material is used in the manufacture of concrete and the formation of slabs. If the components have a fractionation of 10 to 20 millimeters, then the material can be used in the formation of roadbeds, the creation of foundations for buildings for various purposes, as well as in the process of building bridges. Components from 20 to 40 millimeters are most often used in the manufacture of heavy and complex structures. If there is a need to equip a roadway or build a multi-storey building, then fractions ranging from 40 to 70 millimeters are used. When carrying out decorative work, crushed stone sizes from 70 to 120 millimeters are used. Considering gravel and crushed stone, the difference between which is obvious, it is worth noting that the latter mineral is characterized by excellent strength, as well as resistance to low temperatures. The material may bedifferent groups, which depends on the indicators of frost resistance.
Differences in minerals
Despite the fact that both materials have the same origin, they are used in different directions in construction and finishing work. The first thing you should pay attention to when comparing gravel and crushed stone is the difference in size. It is important to mention the ability to adhere to certain materials.
Gravel in terms of the latest quality is significantly inferior to its opponent. It is for this reason that this mineral is most often used in construction. The physical form of rubble can also be called practical. The planes and corners of the stone contribute to better compaction. This material is able to fill all the voids. If you decide to choose gravel, you can get confused between mountain and granite varieties. It is quite difficult to understand due to the external similarity of the material of different grades. However, different types of gravel have differences that you should definitely consider when buying.
Differences in production and mining
When considering gravel and crushed stone, you should notice the difference between these two minerals and in particular production and extraction. The first natural material is loose loose fragments that do not have clearly defined edges. Gravel can be formed exclusively in natural conditions, during the temporary natural destruction of rock. If the gravel has a fraction that exceeds 80 millimeters, then it is crushed intorubble. The sea and river type of this mineral has a more sloping surface, for this reason it is rarely used in construction. Usually, a method is used for mining, which involves the collection of a placer of stones that lies on the surface. In this case, a special technique is used. If necessary, the stones are subjected to additional processing, which includes screening, calibration, and washing. Considering gravel and crushed stone, the difference between which is described in the article, you must take into account that the first material does not have foreign impurities precisely for the reason that the mineral undergoes artificial washing, which frees it from impurities such as soil, clay and sand. As a result, it is possible to obtain gravel, which is freed from sedimentary impurities.
Additional differences
The difference between gravel and crushed stone is also that the first type of mineral suggests the presence of all kinds of rocks. For this reason, it is necessary to evaluate the strength and resistance to temperature effects by making several samples, while easily destructible and weak grains are involved in the process.
Crushed stone production features
Gravel and crushed stone, the differences, photos of which you can read and consider in the article, are produced and mined in different ways. For example, crushed stone is obtained by stripping, after which crushing machines come into play. The type of the latter is determined by the quality of the final product. During the production process, crushed stone can be obtained, in which there is a certain amount of flat grains. The smaller their volume is contained in the bulk, the morea mineral is considered to be of high quality.
