Some buyers, wanting to buy crushed stone, call this building material with gravel, others, on the contrary, gravel is called rubble. Such a confusion with the names is most likely caused by the fact that they both have natural origins. And perhaps, people confuse such a thing as gravel crusp. Both materials are mined from rocks, but at the same time they have a number of differences.

Methods for producing rubble and varieties of material

To better understand what between gravel and rubble there are differences, it is necessary to be in the essence of how these breeds are obtained. Let's start with rubble. This material may initially be a granite rock, can be gravel, limestone, secondary and slag. The process of production of granite rubbing begins with a series of explosions, during which various granite blocks are chipped from the rock. The remaining large pieces explode again. Grinding and sorting to granite fractions is carried out at the factory, where the stones are brought by special equipment.

In certain cases, primary crushing is carried out in a quarry using special techniqueAfter that, the crushing and sorting enterprise is the supply of partially crushed stone.

Gravel crushed stone is obtained as a result of sieving through a special vibration sieve of a career rock, as well as by grinding a stone cliff. Depending on the production method, this type of material is divided into crushed crushed stone and gravel. The stones found use in the production of reinforced concrete construction products and in the arrangement of roads. Both types of building materials are inferior by the strength of granite rubber. Limestone (dolomite) material is obtained in the process of chopping limestone. The stone is a mining sedimentary breed formed mainly from calcite. Dolomita found use in the construction of roads and the manufacture of the LCBC.

Secondary crushed stone is mined by recycling construction trash. For this purpose, it can be crushed and divided into brick fractions, pieces of asphalt and concrete. This process has its own standards, which are described in GOST 25137-82. The main advantage of secondary raw materials is its low cost. The material found use when arranged the bottom of the bottoms and tranches of engineering networks, in the road sphere (used as a outer) and in the manufacture of concrete (used as a large aggregate).

Slagstone is a product of grinding of the demand metallurgical slag and its treatment with fire. Slag cast rubble divide on the fraction. Depending on the brand, which is assigned to a bulk material, taking into account the level of strength, slags are used either in the construction of roads, or in the manufacture of cement concrete of various brands.

Mining sedimentary rocks and scope of their application

Gravel is the result of long-term destruction and weathering of rocks. Building material is sea, river, glacial and mountain. Such pebbles contain sand, clay and dust. They produce them in open and closed careers with the help of dredgers, bulldozers, excavators and other heavy special equipment.

Of these varieties in construction, a sedimentary breed of mountainous origin is most often used. It has a rough surface, due to which the adhesive abilities of the materials connected. The sequence of gravel stones is divided into flushing (allows you to separate the breed from foreign impurities), crushing and sorting. As for the field of application of mountain gravel, this breed is used:

• in the manufacture of heavy cement concrete;
• in the construction of roads and unscrewing congresses;
• with the arrangement of the airbag on a different kind of platforms;
• in the process of laying the foundations;
• in the manufacture of roofing products.

Sea and river sedimentary rock is cleaner, since it contains a minimum amount of impurities. But the very smooth surface of the stones does not allow them to use them for the manufacture of high-quality heavy concrete. Gravel, mined on river and sea beaches is widely used in construction. Due to rounded grain forms, he found use in landscaped work and decoration of various types of plots.

In addition, sea and river pebbles can have different colors, they are gray-blue, dark brown with a red tint, white, black, pink and even yellow. A variety of colors allows them to be used in the process of decorating gardens, ponds, when forming pedestrian tracks, playgrounds, when breakdown, flower beds and flower beds.

So what differs gravel from rubble?

After reading the methods of gravel and crushedbon production, it is safe to answer the question of what the difference between these two materials:

1. 1. The first difference - different way obtaining material. After all, as mentioned above, a strong explosion is needed for the extraction of rubble, and a special technique for collecting gravel.
2. 2. The main difference between these two types of stones consists in the form and size of grains. Gravel pebbles, compared to rubble, have small sizes and smooth faces, while rubble is larger and with sharp corners.
3. 3. Natural shade of rubbank is limited grayAnd the river and marine pebbles nature endowed with a variety of color scheme.
4. 4. The difference between gravel and crushed stone is also the fact that the first material due to its streamlined form cannot be reliably seized with other construction substances, while any rubble fraction due to its roughness has a high level of adhesive abilities. And thanks to the plane and the presence of sharp corners, it has a well-seal property.

Completing this material, we can conclude: there is a difference between gravel and crushed stone, and you need to say significant. Therefore, going to decorate the garden or home pond, you should not order a couple of tons of rubble on a confident voice, and even the maximum fraction. Not knowing the differences between gravel and rubble, you risk losing the presentable view of your living area.

Natural gravel is a bulk natural material that was formed as a result of the destruction of rocks.

Get it from gravel rocks by sorting and sieving through special sieves. Gravel is the stones of a rounded shape with a rough or smooth surface.

The difference of rubble from gravel

Crushed stone is obtained by fragmentation, followed by sorting by fractions, durable rocks, large butt stones, slag or concrete garbage waste.

Unlike gravel, it is a pointed form with a rough surface. In connection, the industrial production in the crushed is practically absent, therefore it is considered an ideal building material. In natural gravel may contain impurities in the form of fragments of various minerals, up to one centimeter.

The use of gravel and crushed stone in construction is regulated by GOST 8267-93 "Crushed stone and gravel from dense rocks for construction work. Technical conditions. "

Natural crushedbon, is an acute-angular fragments of rocks formed at the expense of natural erosion from wind and water, it is rare in small quantities and, as a rule, industrial value does not represent.

Natural gravel, in contrast to rubble, the first class on radioactivity is assigned, so it can be used without limitation in any areas of construction.

Types of gravel

Depending on natural origin and production method, several types of gravel distinguish:

• mountain;
• cut;
• river;
• nautical;
• glacial;
• lake.

Natural gravel has a loose structure, inhomogeneous flexible color, so the modern industry has mastered the production of natural gravel from any rocks, specified color, shape and grain, which can satisfy any requests for the modern building market.

In the form of exception, the artificial type of gravel is distinguished, obtained at factories in the furnaces by high-temperature swelling from clay, silicate raw materials or slag.

Gravel fractions

The fraction is called bulk or lump material defined by strictly dedicated properties. From here, gravel fractions are separated by particle or grain size, so exists:

• small, representing pebbles in size from 1 to 2.5 mm in diameter;
• medium, having dimensions from 2.5 to 5 mm;
• large, with stones size from 5 to 10 mm;
• very large mainly from 10 to 20 mm, less often up to 50 mm.

The larger fractions that exist in the nature of the larger fractions with a size of up to 120 mm still must be considered a butte stone.

Density

Holding the need for materials it is necessary to take into account the density and specific gravity. So claymzite gravel will have a value of 200 to 800 kg / m3, from Schingizitis from 400 to 800 kg / m3.

Keep in mind that the proportion of artificial types of gravel is lighter than water, with all the consequences arising from this and on the subference of the tracks in the low-income parts of the landscape, it is not suitable.

For sales different species And gravel varieties, as a rule, the density value is well known to the seller, and the range of values \u200b\u200blies from 1400 to 1700 kg / m3, in the enlarged construction calculations, the amount of 1560 kg / m3 is mainly used. These figures show the density of the gravel soil, without a mechanical seal and an additional traam.

Application area

Gravel is used:

• for the manufacture of light concrete;
• in the improvement of parks and stadiums;
• with roads;
• as an element of drainage systems;
• in landscape design;
• for the manufacture of decorative coating films;
• filtration clean water in springs and wells.

So, artificially made gravel sizes from 2.5 to 5 mm wake up tracks in parks and squares. Fractions with grain size from 5 to 20 mm are in great demand in the arrangement of country territories, like decorative material for dumbling tracks and creating a flower. The largest fractions of up to 120 mm magnitude, natural gravel, are used in decoration and decoration of walls, foundations, as well as in masonry of fences.

Artificial ceramzite and shingizite gravel is used in the form of a mechanically resistant heat insulator in construction work.

For gravel having a sea or river origin, a smooth surface that does not contribute to a good adhesion with sand and cement, so it is not recommended to use these species in the manufacture of heavy brands of concrete.

Gravel production

Gravel is developed in gravel and sand fields. The amount of stone in the extracted raw material does not exceed 35%, so the method of using quarries provides for the simultaneous production of construction sand and natural gravel.

At the initial stage, sand houses are used for the separation of the main masses of sand and stone, where large number Water is mixed with the extracted mass and its separation due to the gravity forces when the breed is blurred by water. Further, the separated gravel mixture enters the vibro-thread for subsequent purification from impurities and sorting in size and fractions, such a process is called screening.

Vibrothots are special devices where workers are consisting of one or more lattices.

If the grille is one, then the size of the holes in the lattice in the direction of the movement of the raw material changes from the largest at the beginning to the smallest at the end of the design. If the lattices are several, then they are located in a vertical projection over each other or sequentially one after the other in a rigidly reinforced vibrating box, which, in turn, is mounted in suspended form to mounted springs or springs. On each grille, the size of the holes is made so that it makes it possible to comply with only the grains of strictly defined values, which must be isolated from the rock at this stage. Different crashes on the method of creating a vibration pulse and transfer it to sorting lattices. So, there are machines on the inertial, electromagnetic and eccentric principle of mechanical transmission of energy to sorting sits.

Walkways from gravel with their own hands

Recently, the main sphere where gravel is still widely used is the arrangement of territories country houses And cottages or how fashionable it is now called - in landscape design. Everyone can show their designer talent using a diverse view, size and color of gravel. Construction alpine hill Or the previously unprecedented construction of the stone is as easy as to write a picture of oil, but make a decorative platform or pour over the adjacent territory dacha house Convenient tracks are not as simple as it may seem, at first glance, but forces everyone would be desire.

An independent device of tracks from gravel stone or pebbles can be divided into several stages, compliance with which will allow you in series and without excess costs to embody their ideas and surprise those around their talent. And so, proceed:

• The first stage or preparation. Here it is necessary to perform a sketch of future decorative sites on paper, tracks and other planned elements of the landscape.
• At the second stage, using a roulette, pegs and ropes, we make markup of the location of future construction objects in strict accordance with the designed sketch, well, or if necessary, we make adjustments to the improvement plan of your territory.
• In the third stage, after all the boundaries are defined and outlined, all pegs are placed and all ropes are stretched directly to the implementation of the plan. Under all future tracks and platforms with the help of shovels, we remove the fertile layer of land, which, as a rule, is no more than 15 cm. It will save you on a certain time From weeds and grass. The resulting primer can simply be evenly scattered according to the existing lawns or save somewhere for future flower beds.
• At the next stage, on the bottom of the resulting trenches and deepends we fall asleep and thoroughly trambling a large gravel or rubbank, you can also use a solid construction trash from bricks and concrete debris. The volume of filling should be about half to two third depths of the dug deepening. After the tucking to increase the strength, shed the resulting base with water. It is not recommended for the device bases of tracks and sites to wake up their clay, it is worth eliminating the possibility of a cluster of large mass of water during the rain or abundant melting of snow.
• Further, a layer of purchased or prepared decorative gravel is poured on the prepared base. MUST when dripping tracks, use gravel or pebbles of different colors, which is much diverse general form Landscape. And it is also necessary to align and moderate tamping of the surfaces of the surfaces.
• The final conclusion will be required designer decoration Total landscape design. Here you can use various stones, flower beds and other decorative trifles or copyrighted fakes.

Everyone can now enjoy the results of your work and rejoice for beautiful decoration adjacent territory of your country lady.

And in conclusion, we suggest watching video from original ideas Registration of pebbles:

Before listed the differences between rubble and gravel, it is necessary to define gravel.

What is gravel?

Gravel- These are returned (rounded shape, with fuzzy faces) of rock fragments formed as a result of natural (natural) destruction of solid rocks. Those. Gravel is the material, created by nature .

Gravel can have different sizes (fractions): from small, slightly larger grain (5 mm), to very large, more than 70 mm (so-called boulders).

What is a PGS?

In nature, gravel lies along with sand. Such a mixture of sand and gravel is called a sandy gravel mixture, or PGS.

Sand-gravel mixture (PGS)

Mountain breed, depending on the content of gravel and boulders (in% by weight), is divided into 3 types:
1) sand breed (gravel - up to 10%, boulders - 0%);
2) sand-gravel breed (gravel - more than 10%, boulders - up to 5%);
3) Voonno-gravel-sand breed (gravel - more than 10%, boulders - more than 5%).

To obtain gravel from such a rock, it is necessary to separate it from the sand. Next, gravel can be sorted by the necessary fractions using the screening process (dispersion through a set of SIT).

Since gravel is formed in nature as a result of the natural and long destruction of rocks, it has many extraneous inclusions, such as clay, grain, particles, particles organic substances et al. Therefore, to obtain a cleaner material of gravel, it is necessary to rinse with water. After that, it turns out the pure washed gravel.

Myoye Gravel

Now we turn to the differences between rubble and gravel.

What is rubble?

Crusheden - This is a bulk material with grains of greater than 5 mm, derived by crushing Mountain breeds, gravel or boulders.

To get crushed stone from gravel or boulders, the starting material is delivered to crushing and sorting machines (mills, crushers and screens), where gravel (boulders) are crushed. After that, the crushed stone resulting as a result of crushing with the help of screens dispel on the desired fractions.

We get the first difference of rubble from gravel: Crushed stone is a crushing product. Those. Crushed stone, unlike gravel, is not produced in nature in the finished form, and is performed using crushing equipment.

According to GOST 8267-93 "Crushed stone and gravel from dense rocks for construction work", which is the main document regulating the requirements for the quality of these materials, crushed stone from gravel and boulders must contain crushed grains in an amount of at least 80% by weight . At the same time, the grain is considered crushed if its surface of the slope is more than half.

The second difference of rubble from gravel It is that crushed stone can be a product of crushing not only gravel or boulders, but also other rocks, such as granite, diabase, limestone, etc. From gravel and boulders, gravel crushed stone produced, from other rocks crushed stone, which His physical I. chemical properties May differ significantly from gravel.

Third differenceIt should be noted - this is the difference in the cost of materials. Because The production technology of gravel rubble compared with the production of gravel additionally requires the use of crushing equipment, this is reflected in the rise in price of rubble. In this regard, Gravel, as a rule, is cheaper than rubble. There may be unscrupulous suppliers on this, which under the guise of rubble will bring gravel, i.e. Not crushed material, trying to get additional income on the price difference. Therefore, if you order crushed stone, be sure to check that the amount of crushed grains in it corresponds to GOST.

Another difference - this is different sphere Applications of these materials. Since gravel has a more rounded shape, it is inferior to rubble according to the characteristics of the clutch with other materials. The crushed stone due to its angular and rough surface is used as a filler in concrete and asphalt concrete mixtures (fixed in them), as well as during road construction (it is better to be rambling). Gravel is most often used in the construction of drainage systems, as well as as decorative material In landscape design.

For a non-specialist, the difference between these terms is missing, because crushed stone, and gravel - inorganic materials, and the scope of application is the same. But there are still differences.

Both materials of natural origin and are most often used in construction as a coarse aggregate concrete mixture or with a roadbed device. In the question, what is the difference between gravel from rubble, it is necessary to highlight:

1. Method of production - if crushed stone is obtained on a stone-friendly plant (granite, limestone, dolomite act as a raw material, and its competitor has a natural origin;

2. The difference in adhesion with a concrete mixture is noticeable. Roughness and cuboid form provides a stronger connection;

3. When crushing granite at the factory, the raw materials are repeatedly washed, therefore the content of clay particles in it is less;

4. The listed differences affect the application. The smooth surface does not allow to use it for heavy concrete.

If the bulk of the rubble has a cuboid form, then its analog is rounded, the river has a smooth surface. In construction, the application found gravel crushed stone - it costs less than the usual, and has a slightly lower strength and roughness.

Scope and basic requirements

Standards put forward a number of requirements:

1. The compressive strength is established when testing with the press;

2. The resistance to abrasion in the cylindrical drum is checked, the crushed stone, unlike gravel, is better resisting such a load;

3. The presence of body grains is normal;

4. Depending on the fraction, the size of the main part of the grains is set;

5. Frost resistance takes into account the number of alternate freezing cycles in freezer and subsequent thawing, which withstands the sample without destruction. In hard climatic conditions A concrete containing only granite crushed stone is used;

6. The content of clay inclusions is normalized.

You can select such use options as:

• component in a concrete / asphalt mixture;
• in construction road roads For the device of the pavement layers, as well as on the Lower categories, where, instead of asphalt concrete, mineral material is used fortified by organic binders;
• the differences in gravel from rubble are also in the fact that it can be used in decorative purposes, for example, in the device of artificial reservoirs. Another option is the dumping of garden tracks;
• it is possible to use as a coarser-grained filter;
• when the foundations are found at the bottom of the pit, a pillow of a large fraction is pillyled. Thanks to her, water is not stuffed under the sole.

The river and sea type differs in a smooth surface (due to the continuous influence of water), it does not apply in construction. After crushing on the stone-class factory (KDZ), it can be used as a placeholder, but this will reduce the strength of concrete, but the cost will be less. The difference in the cost of the purchase of large filler can be up to 20-30% depending on the type.

Of the total volume of CDZ products per granite accounts for approximately 25%, limestones, dolomite rocks are spent as raw materials for the remaining 75%. Gravel, with the exception of mountain, is more often used in decorative purposes, but after crushing on the KDP, it can be part of low-grade concrete concrete.

Cost comparison

The difference in price often acts as a determining criterion when choosing. The cost of products KDZ is higher, so sometimes it makes sense to choose a cheaper option. On the final price tag influences:

• fraction - the greater the size of the grain, the less time and resources will have to spend on crushing, respectively, the cost will be lower;
• the type of rock than it is harder, the more time it takes her grinding.

A type	Fraction, mm.	Cost, rub / m3
Gravel crusp	0-10	800
	5-20	720
	10-15	750
	20-40	750
Limestone	10-40	770
	40-70	800
	20-40	850
	5-20	870
Granitis	5-10	1700
	5-20	1200
	20-40	900
	25-60	900
	40-70	900
Gravel	5-20	550
	0-80	560
	5-80	580
	20-70	700

These numbers are approximate and may differ by 10-20% largely depending on the manufacturer and the remoteness of the KDZ from the career. Gravel crushed stone by about 15-20% cheaper than the limestone the same fraction, and compared with the granite price difference is 25-35%. This dependence remains for any manufacturer, and the difference in value may even increase.

Both materials have a lot in common, but there are enough differences. They can be used in construction, but the scope differs depending on the physico-mechanical characteristics. In order to save it, you can buy a stone material obtained by fragmentation of river or mountain gravel, it will have less strength compared to granite, but also the cost of acquiring will be reduced.

Along with other sought-after building materials, our company offers its customers gravel crushed stone to buy cheaply. Such a kind of rubble is very popular and uses well-deserved demand from various construction enterprises and private clients. Gravel crushed stone, the price with delivery to which can hesitate depending on the remoteness of the object from the sandy-gravel career is significantly lower than say, the granite rubble.

What is gravel crushed stone and how does it differ from gravel?

The word "gravel" occurred from the French Gravier, which means large sand. This is a mining sedimentary breed, which in its main part consists of rounded shape stones, in contrast to the acute-coronal and cubic granite. By crushing, gravel is obtained gravel crushed stone. This material is one of the most durable, eco-friendly, and the least radioactive. And he has the price with all this lower than the granite of any fraction. These are these reasons and determine the sufficiently wide use of this rock in construction - mainly in the production of concrete and concrete products as a placeholder, as well as in road construction.

Production

Equipment for the production of gravel crushed stone is, as a rule, rotary crushers that crude large rocks In crushed stone with a powerful motor, followed by sorting it according to fractions. The cost of such crushing plants begins from 4 million rubles. The stupor of strength can be in the range of 800-1200 and is determined by GOST 8267-93. This material is produced in almost all regions of Russia, and in particular in our central region, the production and production of gravel crushed stone is mainly located in the Moscow region and the Moscow region. In such settlements, like: der. Nuts, (Ruzsky district), der. Podgorny and Nikolskoye (Dmitrovsky District), Sychevo (Volokolamsky District) and other areas of the Moscow region.

Properties of gravel rubble

Before you buy a gravel crushed stone, it is necessary to determine with the choice of a fraction that you need. In size it is divided into three main fractions:

The first is 5-20 mm, used in the production of concrete and designs from it, repair and construction of roads, where there are no high loads, powder on the roads ...

The second fraction is 20-40 mm. Most in demand. It is used when filling the foundations, concrete production, products from it. Also used in drainage and drainage facilities.

The third fraction is 40-70 mm applied in the same place where the first two. Plus is additionally used in decorating and landscape design.
Radioactive gravel background is significantly lower than granite. Therefore, on the construction of orphanages and structures, the use of such rubble is welcomed. Frost resistance to F400 - a number means the number of freezing and thawing cycles that can withstand a stone without losing its basic properties.
