Glass Brick
Glass brick, also known as glass block, is an architectural element made from glass. The appearance of glass blocks can vary in color, size, texture and form. Glass bricks provide visual obscuration while admitting light. The modern glass block was developed from pre-existing prism lighting principles in the early 1900s to provide natural light in manufacturing plants. Today glass blocks are used in walls, skylights, and sidewalk lights. Attributes Appearance The texture and color of glass blocks can vary in order to provide a range of transparency. Patterns can be pressed into either the inner void or the outside surface of the glass when it is cooling in order to provide differing effects. Glazes or inserts may also be added in order to create a desired private or decorative effect. Standards and grading Glass blocks in Europe are manufactured in accordance with the European Standard EN1052-2. The International Standard is ISO TC 160/SG1. The Standards allow for vari ...

Portland Cement
Portland cement is the most common type of cement in general use around the world as a basic ingredient of concrete, mortar (masonry), 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 (substance), powder, produced by heating limestone and clay minerals in a kiln to form Clinker (cement), clinker, and then #Cement grinding, grinding the clinker with the addition of several percent (often around 5%) gypsum. Several types of portland cement are available. The most common, historically called ordinary portland cement (OPC), is grey, but white portland cement is also available. The cement was so named by Joseph Aspdin, who obtained a patent for it in 1824, because, once hardened, it resembled the fine, pale limestone known as Portland stone, quarried from the windswept cliffs of the Isle of Portland in Dorset. Portland stone was p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Maison De Verre
The Maison de Verre ( French for House of Glass) was built from 1928 to 1932 in Paris, France. Constructed in the early modern style of architecture, the house's design emphasized three primary traits: honesty of materials, variable transparency of forms, and juxtaposition of "industrial" materials and fixtures with a more traditional style of home décor. The primary materials used were steel, glass, and glass block. Some of the notable "industrial" elements included rubberized floor tiles, bare steel beams, perforated metal sheet, heavy industrial light fixtures, and mechanical fixtures. Design Designers The design was a collaboration among Pierre Chareau (a furniture and interiors designer), (a Dutch architect working in Paris since 1927) and Louis Dalbet (craftsman metalworker). Much of the intricate moving scenery of the house was designed on site as the project developed. The historian Henry-Russell Hitchcock as well as the designer Eileen Gray have declared ...

Crown Fountain
''Crown Fountain'' (sometimes known as the "Squirting Faces") is an interactive work of public art and video sculpture featured in Chicago's Millennium Park, which is located in the Chicago Loop, Loop Community areas of Chicago, community area. Designed by Spanish artist Jaume Plensa and executed by Krueck and Sexton Architects, it opened in July 2004. The fountain is composed of a black granite reflecting pool placed between a pair of glass brick towers. The towers are tall, and they use light-emitting diodes (LEDs) to display digital videos on their inward faces. Construction and design of the ''Crown Fountain'' cost $17 million. The water operates from May to October, intermittently cascading down the two towers and spouting through a nozzle on each tower's front face. Residents and critics have praised the fountain for its artistic and entertainment features. It highlights Plensa's Theme (visual arts), themes of dualism, light, and water, extending the use of vid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Edmonton
Edmonton is the capital city of the Provinces and territories of Canada, Canadian province of Alberta. It is situated on the North Saskatchewan River and is the centre of the Edmonton Metropolitan Region, which is surrounded by Central Alberta, Alberta's central region, and is in Treaty 6, Treaty 6 territory. It anchors the northern end of what Statistics Canada defines as the "Calgary–Edmonton Corridor". The area that later became the city of Edmonton was first inhabited by First Nations in Alberta, First Nations peoples and was also a historic site for the Métis in Alberta, Métis. By 1795, many trading posts had been established around the area that later became the Edmonton census metropolitan area. "Fort Edmonton", as it was known, became the main centre for trade in the area after the 1821 merger of the Hudson's Bay Company and the North West Company. It remained sparsely populated until the Canadian acquisition of Rupert's Land in 1870, followed eventually by the arri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oil Lamp
An oil lamp is a lamp used to produce light continuously for a period of time using an oil-based fuel source. The use of oil lamps began thousands of years ago and continues to this day, although their use is less common in modern times. They work in the same way as a candle but with fuel that is liquid at room temperature, so that a container for the oil is required. A textile wick drops down into the oil, and is lit at the end, burning the oil as it is drawn up the wick. Oil lamps are a form of lighting, and were used as an alternative to candles before the use of electric lights. Starting in 1780, the Argand lamp quickly replaced other oil lamps still in their basic ancient form. These in turn were replaced by the kerosene lamp in about 1850. In small towns and rural areas the latter continued in use well into the 20th century, until such areas were finally Electrification, electrified and light bulbs could be used. Sources of fuel for oil lamps include a wide variety of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Porosity
Porosity or void fraction is a measure of the void (i.e. "empty") spaces in a material, and is a fraction of the volume of voids over the total volume, between 0 and 1, or as a percentage between 0% and 100%. Strictly speaking, some tests measure the "accessible void", the total amount of void space accessible from the surface (cf. closed-cell foam). There are many ways to test porosity in a substance or part, such as industrial CT scanning. The term porosity is used in multiple fields including pharmaceutics, ceramics, metallurgy, materials, manufacturing, petrophysics, hydrology, earth sciences, soil mechanics, rock mechanics, and engineering. Void fraction in two-phase flow In gas-liquid two-phase flow, the void fraction is defined as the fraction of the flow-channel volume that is occupied by the gas phase or, alternatively, as the fraction of the cross-sectional area of the channel that is occupied by the gas phase. Void fraction usually varies from location to l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thermal Insulation
Thermal insulation is the reduction of heat transfer (i.e., the transfer of thermal energy between objects of differing temperature) between objects in thermal contact or in range of radiative influence. Thermal insulation can be achieved with specially engineered methods or processes, as well as with suitable object shapes and materials. Heat flow is an inevitable consequence of contact between objects of different temperature. Thermal insulation provides a region of insulation in which thermal conduction is reduced, creating a thermal break or thermal barrier, or thermal radiation is reflected rather than absorbed by the lower-temperature body. The insulating capability of a material is measured as the inverse of thermal conductivity, thermal conductivity (k). Low thermal conductivity is equivalent to high insulating capability (R-value (insulation), resistance value). In thermal engineering, other important properties of insulating materials are product density, density (ρ) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Argon
Argon is a chemical element; it has symbol Ar and atomic number 18. It is in group 18 of the periodic table and is a noble gas. Argon is the third most abundant gas in Earth's atmosphere, at 0.934% (9340 ppmv). It is more than twice as abundant as water vapor (which averages about 4000 ppmv, but varies greatly), 23 times as abundant as carbon dioxide (400 ppmv), and more than 500 times as abundant as neon (18 ppmv). Argon is the most abundant noble gas in Earth's crust, comprising 0.00015% of the crust. Nearly all argon in Earth's atmosphere is radiogenic argon-40, derived from the decay of potassium-40 in Earth's crust. In the universe, argon-36 is by far the most common argon isotope, as it is the most easily produced by stellar nucleosynthesis in supernovas. The name "argon" is derived from the Greek word , neuter singular form of meaning 'lazy' or 'inactive', as a reference to the fact that the element undergoes almost no chemical reactions.

Fireproofing
Fireproofing is rendering something (Building, structures, materials, etc.) resistant to fire, or incombustible; or material for use in making anything fire-proof. It is a passive fire protection measure. "Fireproof" or "fireproofing" can be used as a noun, verb or adjective; it may be hyphenated ("fire-proof"). Applying a certification listing, certification listed fireproofing system to certain structures allows them to have a fire-resistance rating. The term "fireproofing" may be used in conjunction with standards, as reflected in common North American construction specifications. An item classed as fireproof is resistant in specified circumstances, and may burn or be rendered inoperable by fire exceeding the intensity or duration that it is designed to withstand.
