The Background of Limestone and Its Various Uses

Limestone is a type of rock that is formed from the various amount of clay, sand flint and calcite. The calcite generally originates from marine organism and are also present in ground-water that precipitates the material. Limestone therefore is made up of 10% of the total volume of sedimentary rock all over the world.

Limestone is hypersensitive to erosion and there are a lot of eroded land forms such as pot holes ,caves and gorges that comprise a limestone. Limestone therefore are more resistant than any other sedimentary rocks and it is usually found among hills and down lands and typically among clay soils.

This kind of stone can form prominent outcrops by the earth's artefacts and islands. One example of limestone formation can be seen at Clare in Ireland. Limestone rocks are also dominant in Sweden, United States and Australia.

Limestone is also very popular in the realm of architecture as many building manufacturers use limestone for the fact that this type of stone is durable compared to other building materials that are available today. is readily obtainable and relatively easy to cut into blocks and are also good for a more complicated carving. This stone is  long-lasting and can stand up well to any exposure.

In fact, a cement is produced by roasting a powdered limestone added with a powdered clay in a rotary kiln. When the cement is combined with water, sand and crushed rock, a  chemical reaction will then produce a hard stone-like building material that is called concrete.

Limestone is further used as a frontage for most skyscrapers in a way of thin plates for covering than using solid blocks. Bruhn Limestone is the source of high-class quarried limestone that is recognised in Australia.

Pure limestone appear to be more or less white in colour. This is due to its impurities such as clay, organic remains, sand and few other materials that contribute and affect  its colour. Much novel limestone come in various colours, particularly on a weathered surface. Limestone might be crystalline, clastic, granular or hug or one in all depending on its class.
