Crushed stone is secondary. Characteristics, scope

Crushed secondary is produced artificiallywith the help of crushing buildings and structures, namely brick, concrete and asphalt. Then there is grinding into fractions and purification from unnecessary debris, metal and foreign inclusions. The main advantages of this building material are a relatively low cost and a wide range of applications. Also, this rubble is an excellent way to recycle building waste and reuse it. This article will provide information on the main properties of this material and the areas of its application. Also here you can look at the secondary crushed stone, the photos are presented.

Basic properties of crushed stone

Secondary crushed stone is a construction product made by grinding and crushing concrete slabs, buildings, bricks and asphalt. Its main characteristics are:

low cost. The price for this rubble is almost 2 times less, it is natural;
multifunctionality;
large area of application;
increased water resistance.

Other qualities of rubble, such as strength,frost resistance, durability - somewhat lower than that of the natural. However, due to proper and correct application in the right areas and because of the low price, these properties are not of great importance. The most common rubble is secondary with an unsorted fraction, with a size of up to 6 cm or 60 mm. However, the sorted material with fractions from 2 to 4 cm, 4 to 7 cm and 7 to 10 cm is of great popularity.

Crushed stone is secondary. Areas of use

Due to the low price, the rubble of secondary processing is used for the following purposes:

preparation of the foundation for the foundation of buildings and under the floors;
as a filler for concrete;
for the manufacture of concrete and reinforced concrete structures;
for padding in the arrangement of sidewalks and for paths prepared for laying paving slabs;
when constructing temporary and dirt roads, when the price is in priority before qualities;
for padding under parking lots and asphalted platforms for various purposes;
as a replacement of soil during backfilling;
in the fight against landslides;
as a base for water structures;
for the sprinkling of roads and sidewalks during the ice. Here, fine crumb with a fraction up to 10 mm is used;
in the decorative purposes of arrangement of landscape design.

Crushed stone is secondary. Value for construction companies

In the aspirations of entrepreneurs significantlyReduce the cost of production is greatly helped by this kind of rubble. This material makes it possible to reduce costs, while maintaining a decent quality. It is an excellent alternative to materials with a high price and reduces the cost of construction.

Ecology support

Thanks to the utilization of construction debris andthe receipt of secondary material from it, which is then safely used, not only reduces the cost of the facilities received from it, but also preserves and maintains the country's ecology. Therefore, in the modern world, the overproduction of any non-metallic building materials from the resulting waste is increasing.
