Vicat
Vicat SA is a French company manufacturing cement, aggregates and ready-mix concrete in four continents. Its activity has developed in France by vertical integration and abroad by acquisitions and, more recently by building Greenfield factories. It is now present in 12 countries: in France (number three in the market behind Lafarge and Ciments Calcia/Italcementi), in Switzerland (number two in the market), in the United States, in Turkey, in Italy, in Egypt, in Senegal, Mali, Mauritania, Kazakhstan, India and since 2018 in Brazil. History The company was established in 1853 by Joseph Vicat (1821–1902), son of Louis Vicat, who invented artificial cement in 1817. His cement plant was at Genevrey-de-Vif south of Grenoble ( Isère). It used an argillaceous limestone that Joseph Vicat had established as suitable by chemical analysis. The company expanded in 1922 with the construction of a plant at Montalieu nearby. In 1968, HeidelbergCement bought a stake in the compan ...

Louis Vicat
Louis Vicat (31 March 1786, Nevers – 10 April 1861, Grenoble) was a French engineer. He graduated from the École Polytechnique in 1804 and the École des Ponts et Chaussées in 1806. Vicat studied the setting of mortars and developed his own. The first building using it is the bridge at Souillac (Dordogne), erected in 1818. The material was popular but was superseded by Portland cement. He also invented the Vicat needle that is still in use for determining the setting time of concretes and cements. His son Joseph Vicat founded Vicat Cement, which is today a large international cement manufacturing company. He was a member of the French Academy of Sciences and his name is one of the 72 names inscribed on the Eiffel Tower. Vicat was elected a Foreign Honorary Member of the American Academy of Arts and Sciences The American Academy of Arts and Sciences (abbreviation: AAA&S) is one of the oldest learned societies in the United States. It was founded in 1780 during the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Public Company
A public company is a company whose ownership is organized via shares of stock which are intended to be freely traded on a stock exchange or in over-the-counter markets. A public (publicly traded) company can be listed on a stock exchange (listed company), which facilitates the trade of shares, or not ( unlisted public company). In some jurisdictions, public companies over a certain size must be listed on an exchange. In most cases, public companies are ''private'' enterprises in the ''private'' sector, and "public" emphasizes their reporting and trading on the public markets. Public companies are formed within the legal systems of particular states, and therefore have associations and formal designations which are distinct and separate in the polity in which they reside. In the United States, for example, a public company is usually a type of corporation (though a corporation need not be a public company), in the United Kingdom it is usually a public limited company (plc ...

Argillaceous Minerals
Clay minerals are hydrous aluminium phyllosilicates (e.g. kaolin, Al2 Si2 O5( OH)4), sometimes with variable amounts of iron, magnesium, alkali metals, alkaline earths, and other cations found on or near some planetary surfaces. Clay minerals form in the presence of water and have been important to life, and many theories of abiogenesis involve them. They are important constituents of soils, and have been useful to humans since ancient times in agriculture and manufacturing. Properties Clay is a very fine-grained geologic material that develops plasticity when wet, but becomes hard, brittle and non–plastic upon drying or firing. It is a very common material, and is the oldest known ceramic. Prehistoric humans discovered the useful properties of clay and used it for making pottery. The chemistry of clay, including its capacity to retain nutrient cations such as potassium and ammonium, is important to soil fertility. Because the individual particles in clay are l ...
