Rugby Cement
Rugby Cement was the common name for a company based principally in Rugby, Warwickshire, which produced portland cement. With its origins in the early 19th century, the company was founded in 1862 as the Rugby Lias Lime & Cement Company Ltd before being renamed the Rugby Portland Cement Company Ltd in 1872, in 1979 it was renamed the Rugby Group plc. In 2000 Rugby Cement was taken over by the RMC Group, which was itself taken over by the Mexican firm Cemex in 2005. Cement production still continues at the New Bilton site in Rugby under Cemex ownership. History The business was first started in 1825 as a small family business by two local businessmen Thomas Walker and his son George Walker when they started producing lime mortar at a site on their land at New Bilton and nearby Newbold-on-Avon, exploiting locally available deposits of what Professor H.B. Woodward described in 1898 as "the finest inland section of lower lias limestone in the country". The first public company th ...

Cement
A cement is a binder, a chemical substance used for construction that sets, hardens, and adheres to other materials to bind them together. Cement is seldom used on its own, but rather to bind sand and gravel ( aggregate) together. Cement mixed with fine aggregate produces mortar for masonry, or with sand and gravel, produces concrete. Concrete is the most widely used material in existence and is behind only water as the planet's most-consumed resource. Cements used in construction are usually inorganic, often lime or calcium silicate based, which can be characterized as hydraulic or the less common non-hydraulic, depending on the ability of the cement to set in the presence of water (see hydraulic and non-hydraulic lime plaster). Hydraulic cements (e.g., Portland cement) set and become adhesive through a chemical reaction between the dry ingredients and water. The chemical reaction results in mineral hydrates that are not very water-soluble and so are quite durable i ...

Blue Lias
The Blue Lias is a geological formation in southern, eastern and western England and parts of South Wales, part of the Lias Group. The Blue Lias consists of a sequence of limestone and shale layers, laid down in latest Triassic and early Jurassic times, between 195 and 200 million years ago. The Blue Lias is famous for its fossils, especially ammonites. Its age corresponds to the Rhaetian to lower Sinemurian stages of the geological timescale, thus fully including the Hettangian stage. It is the lowest of the three divisions of the Lower Jurassic period and, as such, is also given the name ''Lower Lias''. Stratigraphically it can be subdivided into three members: the Wilmcote Limestone, Saltford Shale and Rugby Limestone. Lithology and facies The Blue Lias comprises decimetre scale alternations of argillaceous limestone and mudstone. These alternations are caused by short-term climatic variations during the Early Jurassic attributed to orbital forcing ( Milankovitch cycles). T ...

Bedfordshire
Bedfordshire (; abbreviated Beds) is a ceremonial county in the East of England. The county has been administered by three unitary authorities, Borough of Bedford, Central Bedfordshire and Borough of Luton, since Bedfordshire County Council was abolished in 2009. Bedfordshire is bordered by Cambridgeshire to the east and north-east, Northamptonshire to the north, Buckinghamshire to the west and Hertfordshire to the south-east and south. It is the fourteenth most densely populated county of England, with over half the population of the county living in the two largest built-up areas: Luton (258,018) and Bedford (106,940). The highest elevation point is on Dunstable Downs in the Chilterns. History The first recorded use of the name in 1011 was "Bedanfordscir," meaning the shire or county of Bedford, which itself means "Beda's ford" (river crossing). Bedfordshire was historically divided into nine hundreds: Barford, Biggleswade, Clifton, Flitt, Manshead, Redbo ...

Chalk
Chalk is a soft, white, porous, sedimentary carbonate rock. It is a form of limestone composed of the mineral calcite and originally formed deep under the sea by the compression of microscopic plankton that had settled to the sea floor. Chalk is common throughout Western Europe, where deposits underlie parts of France, and steep cliffs are often seen where they meet the sea in places such as the Dover cliffs on the Kent coast of the English Channel. Chalk is mined for use in industry, such as for quicklime, bricks and builder's putty, and in agriculture, for raising pH in soils with high acidity. It is also used for " blackboard chalk" for writing and drawing on various types of surfaces, although these can also be manufactured from other carbonate-based minerals, or gypsum. Description Chalk is a fine-textured, earthy type of limestone distinguished by its light color, softness, and high porosity. It is composed mostly of tiny fragments of the calcite shells ...
