Isaac Charles Johnson
Isaac Charles Johnson (28 January 1811 – 29 November 1911) was a British cement manufacturer, and a pioneer of the Portland cement industry. Born in London, his father was a charge-hand at Francis & White's "Roman Cement" plant in Nine Elms. He himself worked there as a labourer from age 16 while studying chemistry. In 1833 he became manager of John Bazeley White's cement plant at Swanscombe on the Thames Estuary which at that time was producing "Artificial Cement" and "Roman Cement". Joseph Aspdin's product was successful but very expensive, and was later improved independently by his son William. Johnson set to work trying to discover its composition but because Aspdin's product was protected by explicit patents and extreme secrecy it was impossible to market a copy. After nearly two years' work, he succeeded and started marketing his own considerably improved version. Johnson, a highly moral man, Mayor of Gateshead and a JP, was able to claim that he was the inventor of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Portland Cement
Portland cement is the most common type of cement in general use around the world as a basic ingredient of concrete, mortar, stucco, and non-specialty grout. It was developed from other types of hydraulic lime in England in the early 19th century by Joseph Aspdin, and is usually made from limestone. It is a fine powder, produced by heating limestone and clay minerals in a kiln to form clinker, grinding the clinker, and adding 2 to 3 percent of gypsum. Several types of portland cement are available. The most common, called ordinary portland cement (OPC), is grey, but white Portland cement is also available. Its name is derived from its resemblance to Portland stone which was quarried on the Isle of Portland in Dorset, England. It was named by Joseph Aspdin who obtained a patent for it in 1824. His son William Aspdin is regarded as the inventor of "modern" portland cement due to his developments in the 1840s. The low cost and widespread availability of the limestone, shales ...

Kent
Kent is a county in South East England and one of the home counties. It borders Greater London to the north-west, Surrey to the west and East Sussex to the south-west, and Essex to the north across the estuary of the River Thames; it faces the French department of Pas-de-Calais across the Strait of Dover. The county town is Maidstone. It is the fifth most populous county in England, the most populous non-Metropolitan county and the most populous of the home counties. Kent was one of the first British territories to be settled by Germanic tribes, most notably the Jutes, following the withdrawal of the Romans. Canterbury Cathedral in Kent, the oldest cathedral in England, has been the seat of the Archbishops of Canterbury since the conversion of England to Christianity that began in the 6th century with Saint Augustine. Rochester Cathedral in Medway is England's second-oldest cathedral. Located between London and the Strait of Dover, which separates England from mainla ...

Men Centenarians
A man is an adult male human. Prior to adulthood, a male human is referred to as a boy (a male child or adolescent). Like most other male mammals, a man's genome usually inherits an X chromosome from the mother and a Y chromosome from the father. Sex differentiation of the male fetus is governed by the SRY gene on the Y chromosome. During puberty, hormones which stimulate androgen production result in the development of secondary sexual characteristics, thus exhibiting greater differences between the sexes. These include greater muscle mass, the growth of facial hair and a lower body fat composition. Male anatomy is distinguished from female anatomy by the male reproductive system, which includes the penis, testicles, sperm duct, prostate gland and the epididymis, and by secondary sex characteristics, including a narrower pelvis, narrower hips, and smaller breasts without mammary glands. Throughout human history, traditional gender roles have often defined ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Blue Circle Industries
Blue Circle Industries was a British public company manufacturing cement. It was founded in 1900 as the Associated Portland Cement Manufacturers Ltd through the fusion of 24 cement works, mostly around on the Thames and Medway estuaries, together having around a 70% market share of the British cement market. In 1911, the British Portland Cement Manufacturers Ltd was formed by the addition of a further 35 companies, creating a company with an initial 80% of the British cement market. Subsequently, the company expanded overseas, predominantly into commonwealth countries and South and Central America. The energy crisis of the 1970 caused the contraction of the company, and the sale of its overseas plants. In 1978, the company's name was changed to ''Blue Circle''. In 2001 the company was bought by Lafarge. History The company was founded in 1900 as ''Associated Portland Cement Manufacturers Ltd'' by the amalgamation of 24 cement companies, owning 35 cement plants, all but two ...

Rotary Kiln
A rotary kiln is a pyroprocessing device used to raise materials to a high temperature (calcination) in a continuous process. Materials produced using rotary kilns include: * Cement * Lime * Refractories * Metakaolin * Titanium dioxide * Alumina * Vermiculite * Iron ore pellets They are also used for roasting a wide variety of sulfide ores prior to metal extraction. Principle of operation The kiln is a cylindrical vessel, inclined slightly from the horizontal, which is rotated slowly about its longitudinal axis. The process feedstock is fed into the upper end of the cylinder. As the kiln rotates, material gradually moves down toward the lower end, and may undergo a certain amount of stirring and mixing. Hot gases pass along the kiln, sometimes in the same direction as the process material (co-current), but usually in the opposite direction (counter-current). The hot gases may be generated in an external furnace, or may be generated by a flame inside the kiln. Such a flam ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Greenhithe
Greenhithe is a village in the Borough of Dartford in Kent, England, and the civil parish of Swanscombe and Greenhithe. It is located east of Dartford and west of Gravesend. Area In the past, Greenhithe's waterfront on the estuary of the river Thames was used to build wharves for transshipping corn, wood and other commodities; its largest cargoes were of chalk and lime. This led in turn to the development of the cement industry at nearby Swanscombe. Greenhithe itself enjoyed a brief period of popularity during Victorian times as a tourist resort, with the building of Greenhithe Pier (now lost) in 1842. Its manor house has been fully restored and the village is accessible to the M25 motorway, High Speed 1's Ebbsfleet International station and, particularly relevant to its local economy, Bluewater shopping centre. History The social history of Greenhithe is bound up in terms of its rectory revenues and manors until the 20th century with its ecclesiastical parish, which is Swa ...
