Today, natural finishing stones – granite, marble and others – are often replaced by artificial materials. However, you can call them analogues with a big stretch, since with the original imitators only related to the appearance. But the properties are completely different.
Take, for example, widespread and advertised today on TV, radio and in the printing house of Peter, cast stones – marble, granite, etc. D. Speaking generally, these materials are produced by kneading polymer binders and natural stone crumbs. In this case, a special technology is used, a certain temperature, pressure and other technical characteristics are withstanded. As a result, at the exit we get material, more plastic and less fragile than natural stone, which also has good operational qualities and quite attractive externally.
On the other hand, the production of cast stones is just one of the ways to simulate a natural mineral or breed. But since the development of air conditioning careers is very expensive, such technologies are very in demand in our time.
In recent years, the demand for artificial stone has increased so much that the mass distribution of enterprises has begun that do not engage in the extraction of stone and, as a result, do not produce stone crumbs. They produce artificial stone from concrete, and the appearance and fortress of the obtained building materials are absolutely not inferior in quality to other “substitutes for stone”.
“Stone” concrete finish
Thanks to the abundance of advertising products – leaflets, booklets, business cards, etc., – Not only marble and granite began to be especially popular. Today, artificial stone does not always imitate these well -known finishing rocks. Increasingly, the interior decoration uses “wild” stones with a embossed rough surface, nondescript and gray, but supposedly “close to nature”.
One of the most common technologies for the production of rough concrete “stones” is the use of rubber, silicone or polyurethane forms. In a plastic “formwork”, with a rough relief inside, a special solution of concrete with fillers is poured. After it froze, the plastic shape is neatly removed to use in the future to produce new facing products.
However, there are also other technologies with which you can establish the manufacture of “wild stone” at a faster pace. It is curious, for example, a way when not every “wild stone” is produced separately, but entire plates that simulate masonry already laid on the wall. More precisely, such a plate will be imitated only after it is fixed on the wall. In order for the “stones” to hold reliably, special metal fasteners are laid in the manufacture of plates. They are absolutely invisible outside, but reliably fix the “masonry of wild stone” on the facade.
