Natural and artificial gravel

Rubble from a natural stone formed by special crushing of rocks, which are developed in quarries.By this crushing receive granite, basalt, limestone (dolomite), marble and other types of debris.Many of the properties of this material is directly dependent on the form of granules obtained by crushing.

unnatural, it is an artificial stone chips obtained during the processing of all kinds of construction debris and waste.This building material is used in the same place where its natural counterpart, only on the basis of certain features.Artificial rubble has lower strength than natural.Therefore, its application is limited and not in demand in the construction of complex structures.

On the other hand, it is indispensable for mixing concrete having a low mark, dumping at lower layers in road construction and in landscaping.In addition to its indisputable advantages include lower cost, when compared to take natural gravel from dense rocks.

Basalt crushed stone - the power of volcanoes for construction

As is known, granite rubble differs enviable strength and has excellent performance in almost all indicators.But there is one important drawback of this material - it is his natural radioactivity.Therefore, its use in the construction of residential buildings, as well as public buildings are strictly limited.However, there are enough real replacement of the building material, and it basalt rubble .

turns this material by crushing basalt - volcanic rock mountain, which has fine-grained structure, high thermal conductivity and strength.Mined gravel igneous rocks open way in special pits.

use this building material in the form krupnofraktsionnogo filler in the manufacture of heavy concrete as a facing material in construction of road surface, etc.It is extremely resistant to aggressive environment, is not radioactive, durable, has a high thermal conductivity and hygroscopic.

dolomite and marble in the service builder

There is another rock formation, used for this building material - it is dolomite.This is a sedimentary rock, which are present in admixture of calcite. Dolomite rubble is an environmentally friendly natural materials.It features low water absorption, lack of radioactivity, high frost resistance and durability.It is used not only in the construction of buildings and structures, but also in their interior decoration.

Crushed rock, through a variety of impurities, has a wide range of different colors, which is often used during finishing and facing works.

One of the most popular, environmentally friendly and beautiful views of the building material - it marble rubble .He has a long list of advantages: durability, frost resistance, water absorption, eco-friendliness;heat resistance;absence of radioactivity and amazing beauty.

Unfortunately, this natural material is extremely resistant to acids, in addition to this, quickly loses its gloss.Due to its advantages, the scope of the marble gravel is wide enough:

  • producing mosaic-concrete floors;
  • exterior and interior of buildings and structures;
  • as a primer in terrariums and aquariums;
  • in landscape design;
  • as bedding on icy sidewalks, etc.

Rubble from a natural stone is an essential component in many of the construction process, and replacement of the material in these cases to any other in the near future is not expected.
