Than rubble different from gravel?

Beginners builders believe that crushed stone and gravel is the same building material. However, this is not true. Both materials are actively used in the production of concrete materials, laying the roadway, repair and finishing works and garden design. Between them a lot of similarities, but at the same time, the difference is very significant.

What it is?

To begin with, we will understand what is each of these bulk materials.

Gravel

This is a rock formation of a sedimentary type formed during the natural process of destruction of large breeds. In the natural environment, this process is stretched for long millennium and is carried out continuously.

Taking into account the Gravel deposit divided into mountainous, marine, river and glacial. In construction business, the mountain varieties will mostly use – this is explained by the fact that the “water” rocks have a flat, smooth surface, so their adhesion is negligible. In the people, they got the name “pebbles”.

Depending on the size of minerals can have large, small and medium particles, they are distinguished by a rounded form. As part of Gravel, there are often some additional impurities – sand or land, which further reduces adhesion with concrete.

The main advantage of gravel consists in its decorative form, which is why he found wide use when installing garden paths, the arrangement of pools and creating artificial ponds. A variety of tint palette allows you to use sleek gravel for interior panels, artistic compositions, as well as for lining of indoor rooms.

Crusheden

Crushedbon is a product obtained during grinding and further sifting rocks of various types. It is referred to building materials of inorganic origin. Crusp particles can have a wide varied size, ranging from 5 mm and more.

Depending on the base, which is processed into crushed stone, the material is divided into 4 main groups.

Granitis

According to its technical and physical characteristics, this material gives the maximum strength parameters, frost resistance and duration of operation. It requires the maximum cost of energy resources, therefore the price of such material is steadily high.

The source material for the manufacture of this rubble is granite rocks. Crushed stone found an application in where elevated loads are expected on the object under construction or need special strength.

At the same time, granite crushed stone has a small radioactive background. In accordance with GOST, it does not go beyond safe for health. Despite this, the material is not shown for exploitation in housing housing, construction of medical and children’s institutions.

Gravine

This material is obtained by a career method or mined from the bottom of the reservoirs (rivers and lakes). It passes clean, then crushing and finishing sorting into separate fractions. In its strength parameters, it slightly inferior to granted material, respectively, and the price has an affordable.

The main advantage of this material is zero radiation background. This crushed stone is used in the construction of residential buildings, kindergartens, schools and hospitals.

Limestone

One of the cheapest types of rubble, due to this, he is in high demand in the population. Of course, its strength characteristics are far from high, but this material can be used for individual works in low-rise house-building.

By its chemical structure, this is the usual calcium carbonate, in the liquid medium it can dissolve.

Therefore, when building foundations of residential buildings, it is not used, because when in contact with the soil moisture, it will collapse.

Similar crushed stone found an application when performing yard and parking, the arrangement of secondary roads, as well as gardening and park places of recreation.

Secondary

This type of rubble is chopped construction trash.

All varieties of rubbank differ in a rough surface. This material is well adhesive in cement mortar and does not fall on the bottom. After its introduction, the mortar acquires a homogeneous consistency and a uniform density. The most demanded cuboid variants of rubble – they have the maximum density and allow you to create a strong and reliable basis of the structure, especially if granite varieties are used.

Depending on the grain size, several types of rubble are distinguished:

  • 5-10 mm – this fraction is predominantly used in the arrangement of asphalt coatings, the production of paving slabs, borders and other forms of concrete, and it is also part of drainage systems;
  • 10-20 mm – the stone of such sizes was widely used when creating foundations;
  • 20-40 mm – also applies to arrange foundations of multi-storey buildings;
  • 40-70 mm – the largest fractional crushed stone, in demand when erecting railway embankments, airfield coatings and high traffic intensity.

Due to its functional characteristics, rubbank provides the most strong adhesion, so it is indispensable when pouring the solution and the manufacture of building materials.

Comparison of external look

From the first glance to distinguish gravel and rubble not easy. And the other are formed from rocks, are inorganic materials, so they have similar composition. There is also a certain external similarity – pebbles and crushed stone may have the same color, although the surface is the surface more rough.

In fact, the main difference between the materials is their origin. Crushed stone is obtained using explosive work with subsequent processing. Gravel is formed in the process of natural aging rocks under the action of sun, wind, water and other external factors. With all this, crushed stone has larger sizes and provides better grip, so the domestic market has gained more distribution.

Frame form

To obtain rubble, resort to crushing of durable rocks. In the manufacture of gravel, this is not necessary, since it is a finished product of natural origin, formed under the influence of natural processes. Therefore, gravel and looks more accurate, there are no sharp edges in it.

The crushed stone obtained by the crushing method is always angular and it looks less neat compared to pebbles.

The difference between rubble and gravel is also available in terms of parameters of individual fractions. So, for rubble, the dimensions of the particles from 5 to 20 mm are considered small, while for grain gravel 5-10 mm – this is already a big fraction.

Colour

Gravel is presented in a wide variety of color options. It is brown, white, blue and even pink. Such a palette in combination with a rounded shape of grain causes the widespread use of gravel to arrange stylish landscape designs.

Crushed stone – monochrome material. It does not represent any decorative value, its use is limited by construction work.

Other differences

The difference in the origin of both materials predetermines the differences in the clutch parameters for the operational characteristics of gravel and rubble. If we talk about the price, then the cost of tons of gravel and rubble is approximately the same. However, rounded grains gravel quickly fill all empties, so its flow rate on the same area is much higher than rubble. Accordingly, when using pebbles, the total cost of work increases in comparison with crushed stone.

What to choose what is better?

A unambiguous answer to the question of what material is better – rubble or gravel, you can not give. Differences of forms and appearance explain the operational features of these materials.

When using rubbank and pebbles in construction, the difference is reduced to the fact that it is possible to obtain the maximum adhesion with concrete composition only when adding rubble. That is why when building a foundation only he is used. At the same time, the use of crushed stone in garden design is very difficult – this is a technical material, so it does not represent any aesthetic value.

Gravel differs in a rounded form, it is visually more aesthetic and attractive, especially in the river and sea species of pebbles.

Besides Gravel smooth – it looks very beautiful, but does not give the necessary adhesion of sand-cement mass. Finding into the solution, pebbles immediately settles on the bottom – thus, the density and stability of the concrete mass is broken. The basis of such a structure may not withstand intense loads and is pretty quickly starting to crack and collapse.

Due to rounded edges and a flat shape, pebbles has an increased negative impact. When performing road swelling between stones, many free space is formed, so the bulk density of such building materials is very low. This adversely affects the total strength of the canvas.

The benefits of gravel include its aesthetic appearance. It is a unique and original material, but in technical terms will be far from the most successful decision. Although in some cases it can be used to make drainage and concrete mixes with an average degree of strength – in this case, it is possible to achieve a significant reduction in the total value of the solution. But for the manufacture of heavy solutions, as well as products with high strength requirements in the role of filler, it is desirable to use crushed stone.

Gravel crusp

It should be noted that the difference existing between crushed stone and gravel still involves the existence of such a material as gravel crushed stone. It is obtained artificially when the monolithic rock. Gravel crushed stone is characterized by increased strength, while the cost of its production is much lower than during the extraction of granite rubble.

Material features exceptional resistance to critical temperatures and temperature differences.

That is why it is widely in demand when preparing construction foundations. Alternative to him protrudes from the granite, the addition of large gravel is allowed.

conclusions

  • Both building materials have an inorganic origin, but rubbing is obtained due to the mechanical destruction of solid rocks, and gravel is formed when they are naturally destruction.
  • Pebbles has a streamlined shape with a rounded smooth surface. Crusp shape arbitrary and necessarily acute-angled, rough rough grain surface.
  • Crushed stone found its application when solving construction tasks. Gravel applied mainly for the purposes of landscape decor.
  • The main advantage of rubble is reduced to its high adhesion and technical parameters. Gravel advantage – its aesthetic appearance.

During the main differences between the two minerals, it is possible to choose the optimal option for a specific type of work.
