Sandstone is a sedimentary rock formed from sand. If the size of the sand is small, it is called sandstone, and if the size of sand is large, it is called conglomerate. This stone has a beautiful and extraordinary appearance. Some of these stones have a wood-like design and others have a cream color that reminds of the wave of golden deserts.
How sandstone is formed
This sedimentary rock is formed by the deposition of sand along with quartz, feldspar, clay, silica and iron oxide. Some sandstones contain more than 90% quartz, which are called quartz sandstones. Sandstone rocks are formed from the compaction of sand deposits in rivers and deserts. The minerals in each region are involved in the color of the sandstone, for example, red sandstone is formed in the American Southwest. Sandstone stone processing is sanded, leather, bush hammer and guillotine.
After cutting and processing these stones, grooves are created on the surface of the stone, which has made these stones look like wood.
Characteristics of sandstone
Since sand is made up of light-colored minerals. Sandstone stones have a light brown and tan color. Red streaks can be seen in some sandstones, which is due to the presence of iron oxide in these stones. Some sandstones also have blue and gray colors.
Among the salient features of Sandstone, the following can be mentioned:
Reasonable price considering the design and beautiful color of this stone
Very low adhesion, to solve this issue, a scoop should be used.
High resistance to cold and heat
Low sandability and polishability due to the presence of clay minerals
Low bending strength
High water absorption
Lack of resistance to acidic substances
Due to its sandy nature, sandstone has a rough texture.
The chemical properties of sandstones are different from each other. Siliceous sandstones are resistant to acid, but calcareous sandstones react in acidic environments.
Sandstone stones are hard to cut due to the presence of silica element. Many segments are used to cut this stone.
