Full Answer

Sandstone is classified as a sedimentary rock, forming gradually over time in deposits from sheets of minerals and sand. These elements compress and bind over time, forming sandstone pits. Sandstone exists in several natural colors, including brown, pink, purple and red. Sandstone's durable composition makes it valuable in the fields of construction and masonry, as it proves quite weather-resistant. Sandstone resists weathering and fading in many climates, but faces rapid deterioration upon freezing, which causes water damage. In the United States, sandstone initially formed rowhouses in the early 1800s. The 1900s saw increasing use in lighter-colored sandstone. Newly extracted sandstone with the finest grains serves primarily aesthetic purposes, appearing in luxury buildings and homes. Sandstone also forms foundations and walls, and crushes into concrete and asphalt mixtures. Sandstone also resists alkaline and acids, making it ideal for chemical uses.
