Gravel and crushed stone: difference, photo

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 the manipulation of construction is simply irreplaceable. Despite the fact that the materials described have the same origin, they have many differences. Among other things, looking at them, you can immediately notice the visual difference. With a deeper study of the issue, one can not but note the scope of use.

Features of gravel

If you have a desire to understand the propertiesand the characteristics of natural material, it is possible to delve deeper into its origin. This variant is a rock that is formed by a sedimentary method. Gravel is loose enough, and also has impregnations of minerals from solid destroyed elements. There are three varieties, among them: fine, medium, and also large material. The first variety has elements that vary in size from 1 to 1.25 millimeters. Medium-sized stones do not exceed 5 millimeters, as for large inclusions, their dimensions are equal to 10 millimeters. Considering gravel and crushed stone, the differences of which will be described in the article, it is necessary to single out the first type, which can have a different nature of origin. Thus, there are lake, mountain, sea, glacial, as well as river material.

Scope of use

If there is a need for the construction processworks provide the most impressive grip, it is worthwhile preferring a mountain mineral, while river and sea have a smoother surface. This is due to all kinds of impurities such as soil, sand, etc. These features indicate that the construction of a mountain variety is most often used in construction. It is used during the construction of roads, as a filler, for backfilling sites, as well as when kneading a concrete mortar to form a foundation. If you decide to consider gravel and crushed stone (differences), photos of these materials can be found in the article.

Varieties

On sale you can find gravel of variouscolors, it can be brown, pink, yellow or blue. This characteristic allowed us to find the application of this mineral for decorative purposes. If necessary, with its use, you can equip the garden and park areas.

Features of crushed stone

It differs from the above material infirst of all by external characteristics. Thus, the crushed stone is distinguished by a rougher surface, in addition, it has sharp angles. The dimensions of this material most often exceed the dimensions of the gravel. It is mined by the method of 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 gravel, the differences of these materials are described in the article. The dimensions of the latter determine the field of application. If the elements do not exceed 5 millimeters, then it is used for the formation of sites, roads, as well as for protection from ice.

With sizes ranging from 5 to 10 millimetersThe material is used in the manufacture of concrete and the formation of slabs. If the components have a fractionality of 10 to 20 millimeters, the material can be used to form roadblocks, create foundations for buildings of different purposes, and also 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 the roadway or erect a multi-storey building, fractions in the range from 40 to 70 millimeters are used. When performing decorative works, the dimensions of crushed stone are used from 70 to 120 millimeters. Considering gravel and crushed stone, the difference between them is obvious, it is worth noting that the last mineral is characterized by excellent strength, and also resistance to low temperatures. The material can belong to different groups, which depends on the indicators of frost resistance.

Distinctions of minerals

Despite the fact that both materials have the sameorigin, they are used in different directions in the construction and finishing works. 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 and rubble difference

Gravel with the latest quality is significantlyinferior to his opponent. It is for this reason that this mineral is most often used in construction. The physical form of crushed stone can also be called practical. The planes and corners of the stone contribute to better compaction. This material is able to fill all the void spaces. If you decide to choose gravel, you can get confused between the mountain and granite varieties. To understand is rather difficult because of the external similarity of material of different kinds. However, different types of gravel have differences, which must be taken into account when buying.

Differences in production and extraction

the difference between gravel and rubble

Considering gravel and crushed stone, the difference between these twoMinerals you should notice and especially production and mining. The first natural material is loose loose fragments, which do not have clearly defined facets. Gravel can be formed exclusively in natural conditions, during the temporary natural destruction of the rock. If the gravel has a fraction that exceeds 80 millimeters, it is crushed into crushed stone. The marine 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, involving the collection of placer stones, which lies on the surface. In this case, a special technique is used. If necessary, stones are subjected to additional processing, which involves screening, calibration, and washing. Considering gravel and crushed stone, the difference of which is described in the article, you should take into account that the first material does not have extraneous impurities precisely because the mineral undergoes an artificial washing that releases it from the impurity by the type of soil, clay and sand. As a result, it is possible to obtain gravel, which is freed from sediment.

Additional differences

The difference between gravel and gravel is also inThe fact that the first type of mineral involves the presence of all kinds of rocks. For this reason, it is necessary to evaluate the strength and resistance to the effects of temperatures by making several selections, while the process involves easily destroyed and weak grains.

Features of crushed stone production

Gravel and crushed stone, differences, photos of which you canread and consider in the article, produced and extracted in different ways. For example, crushed stone is obtained by the method of stripping, after which the crushers enter the business. The type of the latter is determined by the quality of the final product. In the production process, crushed stone can be obtained, in which there is a certain number of flat grains. The smaller their volume is contained in the bulk, the more qualitative is the mineral.
