Sandstone is a coarse grained sedimentary rock composed of small grains cemented by siliceous, felspathic, or calcareous cementing material. Sandstone is formed by the consolidation and aggregation of sand and held together by a natural cement, such as silica.
The cementing material determines the durability and color of the rock.
It is mostly available in reddish, white, grayish or yellowish colors.
Sandstone has varied applications as building stones.
