Crushed stone is produced artificially by crushing buildings and structures, namely brick, concrete and asph alt. Then there is grinding into fractions and purification from unnecessary debris, metal and foreign inclusions. The main advantages of this building material are relatively low cost and a wide range of applications. Also, this crushed stone is an excellent way to dispose of construction waste and reuse it. This article will provide information about the main properties of this material and its applications. Also here you can look at the secondary crushed stone, photos are presented.
Basic properties of crushed stone
Recycled crushed stone is a construction product made by grinding and crushing concrete slabs, buildings, bricks and asph alt. Its main characteristics are:
- low cost. The price of this gravel is almost 2times less, it is natural;
- multifunctionality;
- large scope;
- increased water resistance.
The other qualities of crushed stone, such as strength, frost resistance, durability, are somewhat lower than those of natural. However, due to competent and correct application in the right areas and because of the low price, these properties are not of great importance. The most common crushed stone is secondary with an unsorted fraction, with a size of up to 6 cm or 60 mm. However, sorted material with fractions from 2 to 4 cm, 4 to 7 cm and 7 to 10 cm is very popular.
Crushed secondary. Applications
Due to its low price, secondary processing crushed stone is used for the following purposes:
- preparing the base for the foundation of buildings and floors;
- as aggregate for concrete;
- for the manufacture of concrete and reinforced concrete structures;
- for backfilling when arranging sidewalks and for paths prepared for laying paving slabs;
- in the construction of temporary and dirt roads, when price is a priority over quality;
- for filling under parking lots and paved areas for various purposes;
- as a replacement for soil when backfilling;
- in the fight against landslides;
- as a base for water structures;
- for powdering roads and sidewalks during ice. It uses fine crumbs with a fraction of up to 10 mm;
- for decorative landscaping purposes.
Crushed secondary. Value for construction companies
In the desire of entrepreneurs to significantly reduce the cost of production, this type of crushed stone greatly helps. This material makes it possible to reduce costs while maintaining decent quality. It is an excellent alternative to high-priced materials and reduces the cost of structures.
Supporting the environment
Thanks to the disposal of construction waste and the production of secondary material from it, which is subsequently safely used, not only the cost of structures obtained from it is significantly reduced, but the country's ecology is also preserved and supported. Therefore, in the modern world, the overproduction of any non-metallic building materials from the resulting waste is increasing.
