What kind of rock is sandstone?
Time does not spare rocks, and they are gradually destroyed by wind, water and temperature changes. However, the smallest grains of minerals do not scatter with dust, but settle in depressions, where, cemented by the smallest fractions under the influence of atmospheric moisture, they become a natural analogue of an artificial stone - a natural stone sandstone. The grains that make up the homogeneous or layered structure of the stone usually have sizes from 0.1 to 2 millimeters, which makes the rock really look like caked sand.
The color of a stone depends not only on what kind of grains it is made of, but also on what mineral acts as a cementing agent.
The rock strength is very high, especially if there is cementing of the particles with siliceous and carbonate substances, is very appreciated because of the high physical and mechanical properties often used for finishing a layered smooth sandstone. The least durable is clay cementing of the rock. High refractoriness is possessed by a stone entirely consisting of quartz inclusions cemented with silicon.
Decorative sandstone limestone and other variants
For the revetment of buildings and landscaping uses a huge amount of materials, and among them not the last place is occupied by natural stone. Moreover, the most suitable for the decoration of walls are those rocks that already have a slab structure in their natural state, among these are the slate and decorative sandstone of the flagstones. Initially having an almost smooth surface, this stone after polishing becomes an ideal outer lining, and also suitable for paving tracks.
For the most part slate is red sandstone, however, despite the name, the breed is rich in shades. In particular, pink stone, burgundy, gray-red, and also purple are widely known and actively used. When choosing a natural cladding, you should be careful, as often the red color of the usual gray-green rock gives roasting. You can understand this by the characteristic ceramic sound when knocking on a tile.
Sandstone artificial, so similar to natural
What nature has created is quite human and human. In our case, this is not about living organisms, but only about the stone. As already mentioned, sandstone is a cemented particle of various minerals. There are monomictic rocks, in which there is only one mineral, oligomictic, from grains of two different constituents, and also polymictic rocks, when different inclusions of more than three .Create an artificial sandstone, cementing a stone crumb, will not be difficult, it can be done even at home.
Advantages of artificial material - in its durability. If a natural stone is destroyed over time, then its man-made analog becomes only stronger. In addition, unlike natural, artificial material has a homogeneous structure, without unnecessary inclusions. To make man-made material in color is also not difficult, for example, green or yellow sandstone will be obtained either by using a filler of the appropriate color, or by using pigments.
