What are the worked out building materials can be used
secondary? This is a brick fight, asphalt crumb, reinforced concrete battle and
crushed crushed stone. These materials remain as a result of dismantling
surviving structures, dismantling the roadway of the one who came to
unusable and other similar events.
The use of secondary building material allows
significantly reduce the costs of construction organizations.
processing, these secondary raw materials are becoming affordable and inexpensive
resources in the production of crushed stone, and road pollination during
road works. So this material has become popular as firms of students
its sale and delivering it,
but and the organizations carrying out construction, because at the expense of
use, brick or concrete battle, you can actively save money
for other investments. For considerations of savings, not only the region, but also
Large cities use secondary building materials.
The most popular is the use of processed concrete, its
processed with greater activity than other materials. And this is quite
justified, at almost any construction site, there is
reinforced concrete battle, which, as a result of processing, is divided into
Production of sand and secondary crushed stone. Crushed stone, and broken brick,
use in road construction, when laying the foundation, raising
level of plots and in the manufacture of heavy concrete.
It is important that the secondary construction material is environmentally friendly
safe, that is, when using there was no highlighting harmful substances.
Therefore, when using secondary raw materials, there are special
norms and quality requirements, even such materials obtained during
processing. There is such a thing as equivalent of materials. That
there is, if the secondary material will fulfill the same requirements,
which are applied to breeds received by extraction, only in this
case we can talk about their equivalent. By the way, the use of secondary ones
building materials helps to contribute to environmental protection
and the preservation of existing natural fossils. Therefore, firms
engaged in the implementation of secondary construction materials, must prove
the safety of its use in the future, this applies to
potential influence for the environment.
