Uses of stone

When one thinks of stone, its use in famous buildings probably first comes to mind, but few people probably realise that stone in some form enters our lives probably a hundred times even before we leave the house each day. Five main groups of uses can be identified:

Building and decorative stone – stone used for its resistance to weather or its aesthetic appeal – walls and decorative purposes. Buildings, walls, paving slabs.

Aggregates – stone used for its strong physical properties – crushed and sorted into various sizes for use in concrete, coated with bitumen to make asphalt or used 'dry' as bulk fill in construction. Mostly used in roads, concrete and building products.

Industrial purposes – limestone can be used for its chemical (mainly alkaline) properties as calcium carbonate (CaCO3) in farming and manufacturing industry.

Lime burning (calcining) – limestone when heated to a high temperature breaks down into lime (calcium oxide) and carbon dioxide gas. It can then be used as a more powerful alkali than limestone (see above) or used as a cement with sand, to make mortar, or as a soil improver in agriculture.

Cement – if limestone (or its variety chalk) is mixed with clay or sandstone before firing, it can produce Portland cement which when mixed with aggregate makes concrete.

Stone from Mendip quarries has been employed in all of these ways (with the exception of Portland cement manufacture).

Lime-burning

Until the 1920s, lime-burning, although small scale, was widespread. The remains of hundreds of small lime-kilns can be seen scattered across Mendip. Since the 1920s, lime burning has been concentrated at larger plants. Throughout the middle of the 20th century, Callow Rock and Gurney Slade quarries were the two main producers, by the 1970s both these had closed but a major new plant was established at Batts Coombe. The main purpose of this investment was to supply the South Wales steel industry at Llanwern and Port Talbot.
