William Aspdin
William Aspdin (23 September 1815 – 11 April 1864) was an English cement manufacturer, and a pioneer of the Portland cement industry. He is considered the inventor of "modern" Portland cement. He has also been termed "an incorrigible liar and swindler". Joseph Aspdin, his father, is proven to have patented the method of cement manufacture in 1824 which is how cement continues to be made to this day, albeit with technological advances. Biography Aspdin was born in Leeds, the second son of Joseph Aspdin, an English cement manufacturer. Joseph Aspdin obtained a patent for "Portland cement" in 1824. His product was a fast-setting material usable only in mortars and stuccos. He joined his father's cement manufacturing firm in 1829, at the age of fourteen. In July 1841, Aspdin left the firm after a major disagreement with his father. Joseph then went into partnership with his elder son, James, posting a notice that Aspdin had left, and that the company would not be responsible ...

Concrete Pioneers
Concrete is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens (cures) over time. Concrete is the second-most-used substance in the world after water, and is the most widely used building material. Its usage worldwide, ton for ton, is twice that of steel, wood, plastics, and aluminum combined. Globally, the ready-mix concrete industry, the largest segment of the concrete market, is projected to exceed $600 billion in revenue by 2025. This widespread use results in a number of environmental impacts. Most notably, the production process for cement produces large volumes of greenhouse gas emissions, leading to net 8% of global emissions. Other environmental concerns include widespread illegal sand mining, impacts on the surrounding environment such as increased surface runoff or urban heat island effect, and potential public health implications from toxic ingredients. Significant research and development is b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Alite
Alite is an impure form of tricalcium silicate, , sometimes formulated as ( in cement chemist notation), typically with 3-4% of substituent oxides. It is the major, and characteristic, phase in Portland cement. The name was given by Törnebohm in 1897 to a crystal identified in microscopic investigation of Portland cement. Hatrurite is the name of a mineral that is substituted . Composition and structure The alite found in Portland cement differs in composition from simple tricalcium silicate. It is a solid solution and contains minor amounts of other oxides besides CaO and . A typical composition is: Based on this, the formula can be expressed as . In practice, the composition varies with the bulk composition of the clinker, subject to certain limits. Substitution of calcium ions or orthosilicate ions requires that electric charges be kept in balance. For instance, a limited number of orthosilicate () ions can be replaced with sulfate () ions, provided that for each sul ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thames Tunnel
The Thames Tunnel is a tunnel beneath the River Thames in London, connecting Rotherhithe and Wapping. It measures 35 feet (11 m) wide by 20 feet (6 m) high and is 1,300 feet (396 m) long, running at a depth of 75 feet (23 m) below the river surface measured at high tide. It is the first tunnel known to have been constructed successfully underneath a navigable river and was built between 1825 and 1843 by Marc Brunel and his son Isambard using the tunnelling shield newly invented by the elder Brunel and Thomas Cochrane. The tunnel was originally designed for horse-drawn carriages, but was mainly used by pedestrians and became a tourist attraction. In 1869 it was converted into a railway tunnel for use by the East London line which, since 2010, is part of the London Overground railway network under the ownership of Transport for London. History and development Construction At the start of the 19th century, there was a pressing need ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marc Isambard Brunel
Sir Marc Isambard Brunel (, ; 25 April 1769 – 12 December 1849) was a French-British engineer who is most famous for the work he did in Britain. He constructed the Thames Tunnel and was the father of Isambard Kingdom Brunel. Born in France, Brunel fled to the United States during the French Revolution. In 1796, he was appointed Chief Engineer of New York City. He moved to London in 1799, where he married Sophia Kingdom. In addition to the construction of the Thames Tunnel, his work as a mechanical engineer included the design of machinery to automate the production of pulley blocks for the Royal Navy. Brunel preferred the given name Isambard, but is generally known to history as Marc to avoid confusion with his more famous son. Early life in France Brunel was the second son of Jean Charles Brunel and Marie-Victoire Lefebvre. Jean Charles was a prosperous farmer in Hacqueville, Normandy, and Marc was born on the family farm. It was customary for the first son to inher ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Con Man
A confidence trick is an attempt to defraud a person or group after first gaining their trust. Confidence tricks exploit victims using their credulity, naïveté, compassion, vanity, confidence, irresponsibility, and greed. Researchers have defined confidence tricks as "a distinctive species of fraudulent conduct ..intending to further voluntary exchanges that are not mutually beneficial", as they "benefit con operators ('con men') at the expense of their victims (the 'marks')". Terminology Synonyms include con, confidence game, confidence scheme, ripoff, scam, and stratagem. The perpetrator of a confidence trick (or "con trick") is often referred to as a confidence (or "con") man, con-artist, or a "grifter". The shell game dates back at least to Ancient Greece. Samuel Thompson (1821–1856) was the original "confidence man". Thompson was a clumsy swindler who asked his victims to express confidence in him by giving him money or their watch rather than gaining their confidenc ...

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 ...
