Zollverein Coal Mine Industrial Complex
The Zollverein Coal Mine Industrial Complex (German Zeche Zollverein) is a large former industrial site in the city of Essen, North Rhine-Westphalia, Germany. The first coal mine on the premises was founded in 1847, and mining activities took place from 1851 until December 23, 1986. For decades, starting in the late 1950s, the two parts of the site, ''Zollverein Coal Mine'' and ''Zollverein Coking Plant'' (erected 1957–1961, closed on June 30, 1993), ranked among the largest of their kinds in Europe. Shaft 12, built in the New Objectivity style, was opened in 1932 and is considered an architectural and technical masterpiece, earning it a reputation as the "most beautiful coal mine in the world". Because of its architecture and testimony to the development of heavy industry in Europe, the industrial complex was inscribed on the UNESCO World Heritage List on December 14, 2001, and is one of the anchor points of the European Route of Industrial Heritage.

Essen
Essen () is the central and, after Dortmund, second-largest city of the Ruhr, the largest urban area in Germany. Its population of makes it the fourth-largest city of North Rhine-Westphalia after Cologne, Düsseldorf and Dortmund, as well as the List of cities in Germany by population, tenth-largest city of Germany. Essen lies in the larger Rhine-Ruhr metropolitan region, List of EU metropolitan regions by GDP#2021 ranking of top 4 German metropolitan regions, second largest by GDP in the EU, and is part of the cultural area of Rhineland. Because of its central location in the Ruhr, Essen is often regarded as the Ruhr's "secret capital". Two rivers flow through the city: the Emscher in the north, and in the south the Ruhr (river), Ruhr River, which is dammed in Essen to form the and reservoirs. The central and northern boroughs of Essen historically belong to the Low German Westphalian dialects area, and the south of the city to the Low Franconian Bergish dialects, Bergish ar ...

Ruhr Area
The Ruhr ( ; , also ''Ruhrpott'' ), also referred to as the Ruhr Area, sometimes Ruhr District, Ruhr Region, or Ruhr Valley, is a polycentric urban area in North Rhine-Westphalia, Germany. With a population density of 1,160/km2 and a population of over 5 million (2017), it is the largest urban area in Germany and the third of the European Union. It consists of several large cities bordered by the rivers Ruhr to the south, Rhine to the west, and Lippe to the north. In the southwest it borders the Bergisches Land. It is considered part of the larger Rhine-Ruhr metropolitan region of more than 10 million people, which is the third largest in Western Europe, behind only London and Paris. The Ruhr cities are, from west to east: Duisburg, Oberhausen, Bottrop, Mülheim an der Ruhr, Essen, Gelsenkirchen, Bochum, Herne, Hagen, Dortmund, Hamm and the districts of Wesel, Recklinghausen, Unna and Ennepe-Ruhr-Kreis.

Reinforced Concrete
Reinforced concrete, also called ferroconcrete or ferro-concrete, is a composite material in which concrete's relatively low tensile strength and ductility are compensated for by the inclusion of reinforcement having higher tensile strength or ductility. The reinforcement is usually, though not necessarily, steel reinforcing bars (known as rebar) and is usually embedded passively in the concrete before the concrete sets. However, post-tensioning is also employed as a technique to reinforce the concrete. In terms of volume used annually, it is one of the most common engineering materials. In corrosion engineering terms, when designed correctly, the alkalinity of the concrete protects the steel rebar from corrosion. Description Reinforcing schemes are generally designed to resist tensile stresses in particular regions of the concrete that might cause unacceptable cracking and/or structural failure. Modern reinforced concrete can contain varied reinforcing materials made o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cube
A cube or regular hexahedron is a three-dimensional space, three-dimensional solid object in geometry, which is bounded by six congruent square (geometry), square faces, a type of polyhedron. It has twelve congruent edges and eight vertices. It is a type of parallelepiped, with pairs of parallel opposite faces, and more specifically a rhombohedron, with congruent edges, and a rectangular cuboid, with right angles between pairs of intersecting faces and pairs of intersecting edges. It is an example of many classes of polyhedra: Platonic solid, regular polyhedron, parallelohedron, zonohedron, and plesiohedron. The dual polyhedron of a cube is the regular octahedron. The cube can be represented in many ways, one of which is the graph known as the cubical graph. It can be constructed by using the Cartesian product of graphs. The cube is the three-dimensional hypercube, a family of polytopes also including the two-dimensional square and four-dimensional tesseract. A cube with 1, unit s ...

Bauhaus
The Staatliches Bauhaus (), commonly known as the , was a German art school operational from 1919 to 1933 that combined Decorative arts, crafts and the fine arts.Oxford Dictionary of Art and Artists (Oxford: Oxford University Press, 4th edn., 2009), , pp. 64–66 The school became famous for its approach to design, which attempted to unify individual artistic vision with the principles of mass production and emphasis on form follows function, function. The Bauhaus was founded by architect Walter Gropius in Weimar. It was grounded in the idea of creating a ''Gesamtkunstwerk'' ("comprehensive artwork") in which all the arts would eventually be brought together. The Bauhaus style later became one of the most influential currents in modern design, Modern architecture, modernist architecture, and architectural education. The Bauhaus movement had a profound influence on subsequent developments in art, architecture, graphic design, interior design, industrial design, and typography. ...

Fritz Schupp
Fritz Schupp (22 December 1896 in Uerdingen – 1 August 1974 in Essen) was a German architect. He was educated from 1914 to 1917 at the Universities of Karlsruhe, München and Stuttgart. Despite mostly working alone, he formed a partnership based in Essen and Berlin with Martin Kremmer. From 1949, Schupp was a lecturer at the Technical University in Hannover. Between 1920 and 1974, he built 69 factories and plants. In the Bergbauarchiv (Bochum), 17500 sketches are at the disposal of researchers.

Coke (fuel)
Coke is a grey, hard, and porous coal-based fuel with a high carbon content. It is made by heating coal or petroleum in the absence of air. Coke is an important industrial product, used mainly in iron ore smelting, but also as a fuel in stoves and forges. The unqualified term "coke" usually refers to the product derived from low-ash and low-sulphur bituminous coal by a process called coking. A similar product called petroleum coke, or pet coke, is obtained from crude petroleum in oil refinery, petroleum refineries. Coke may also be formed naturally by geology, geologic processes.B. Kwiecińska and H. I. Petersen (2004): "Graphite, semi-graphite, natural coke, and natural char classification — ICCP system". ''International Journal of Coal Geology'', volume 57, issue 2, pages 99-116. It is the residue of a destructive distillation process. Production Industrial coke furnaces The industrial production of coke from coal is called coking. The coal is baked in an airless k ...
