concrete pronunciation

Concrete production is a highly intensive energy-consuming process and presently facing a number of challenges in reducing the carbon footprint and making it more economic. [132][133][134], The world record for concrete pumping was set on 7 August 2009 during the construction of the Parbati Hydroelectric Project, near the village of Suind, Himachal Pradesh, India, when the concrete mix was pumped through a vertical height of 715 m (2,346 ft). "Curing Concrete" Peter C. Taylor CRC Press 2013. For example, pumice and other volcanic glasses were added as a natural pozzolanic material for mortars and plasters during the construction of the Villa San Marco in the Roman period (89 B.C. [40] Alternatively, other materials can also be used as a concrete binder: the most prevalent substitute is asphalt, which is used as the binder in asphalt concrete. The process was refined and enhanced by Belgian inventor and U.S. immigrant Edward De Smedt.[78]. [19] During the Roman Empire, Roman concrete (or opus caementicium) was made from quicklime, pozzolana and an aggregate of pumice. Regarding this "workability of concrete definition", the workability of concrete is defined as amount of useful internal work required to be done by the concrete in order to activate full compaction.. For more information see Brutalist architecture. Concrete Nouns: Definition, Example, Worksheet (With PDF) Written by Manasi Dey. Cement & Concrete. [14] Some of these structures survive to this day.[14]. Concrete poetry is a kind of writing that focuses on the shape words make on the page. These shear loads subject the structure to both tensile and compressional loads. Browse the use examples 'plastic concrete' in the great English corpus. Found inside – Page 71concrete interval , it gives up a portion of its movement to that subtonic , which then carries on and completes the vanish . In this way the radical and ... But the number can not , in easy pronunciation , be extended beyond these . 1. a. [50] The most common admixtures are retarders and accelerators. Additional common curing methods include wet burlap and plastic sheeting covering the fresh concrete. Bonding agents are used to create a bond between old and new concrete (typically a type of polymer) with wide temperature tolerance and corrosion resistance. As the reactions proceed, the products of the cement hydration process gradually bond together the individual sand and gravel particles and other components of the concrete to form a solid mass. | Meaning, pronunciation, translations and examples All Free. Significant research and development is being done to try to reduce the emissions or make concrete a source of carbon sequestration, and increase recycled and secondary raw materials content into the mix to achieve a circular economy. Concrete production is the process of mixing together the various ingredients—water, aggregate, cement, and any additives—to produce concrete. To mitigate these effects, post-cooling[109] is commonly applied during construction. The world record for the largest concrete pour in a single project is the Three Gorges Dam in Hubei Province, China by the Three Gorges Corporation. In the Ancient Egyptian and later Roman eras, builders discovered that adding volcanic ash to the mix allowed it to set underwater. This is the British English pronunciation of concrete. [40] Fly ash and slag can enhance some properties of concrete such as fresh properties and durability. How to use concrete in a sentence.

[123] The micro fungi Aspergillus alternaria and Cladosporium were able to grow on samples of concrete used as a radioactive waste barrier in the Chernobyl reactor; leaching aluminum, iron, calcium, and silicon. Major savings in time result from manufacture of structural elements apart from the series of events which determine overall duration of the construction, known by planning engineers as the 'critical path'. Concrete words refer to tangible, qualities or characteristics, things we know through our senses. Water runs through the voids in the pavement to the soil underneath. ; Record yourself saying 'concrete' in full sentences, then watch yourself and listen.You'll be able to mark your mistakes quite easily. CONCRETE: To excel in college, you'll need to do go to every class; do all your Search Result for "concrete": Wordnet 3.0. 'The structure was completed in 1937, using steel and mass concrete with sand quarried in Joe Mangan's field.'. Insulating concrete forms (ICFs) are hollow blocks or panels made of either insulating foam or rastra that are stacked to form the shape of the walls of a building and then filled with reinforced concrete to create the structure. [100] While insulation reduces energy loss through the building envelope, thermal mass uses walls to store and release energy. For other uses, see, End-of-life: concrete degradation and waste, Applications of recycled concrete aggregate.

Hollow core concrete slabs are easy to dismantle and the span is normally constant, making them good for reuse.[122]. Creep is indicated when strain in a solid increases with time while the stress producing the strain is kept constant. This can greatly reduce the weight of beams or slabs, by Lime as the first cement: Since long, Lime has been used to make things like plaster and mortar.

To take a concrete instance, consider the utterance Birds fly. It is estimated that even near complete recovery of concrete from construction and demolition waste will only supply about 20% of total aggregate needs in the developed world.[122]. In pre-tensioned concrete, the prestressing is achieved by using steel or polymer tendons or bars that are subjected to a tensile force prior to casting, or for post-tensioned concrete, after casting. "The floors were cement, in some places hard, but, by long exposure, broken, and now crumbling under the feet." Prefabricated constructions are the prerequisites for constructions necessarily capable of being taken apart. 'The construction of the new building is a reinforced concrete frame with suspended concrete floor slabs.' 'Such houses look like traditional brick built houses, but they incorporate in their construction reinforced concrete columns the embedded steel of which is ineffectively protected against corrosion by the surrounding concrete.' Most notably, the production process for cement produces large volumes of greenhouse gas emissions, leading to net 8% of global emissions. [22], Modern tests show that opus caementicium had as much compressive strength as modern Portland-cement concrete (ca. Tips for Teaching Pronunciation shows English language teachers how to teach the North American sound system. This practical reference book provides practical tips, clear explanations, diagrams, and sample classroom activities. Higher-strength concrete is often used for larger civil projects. Through a series of chemical reactions called hydration, the paste hardens and gains strength to form the rock-like mass known . This is because recycled aggregates often have better compaction properties and require less cement for sub-base uses. concrete synonyms, concrete pronunciation, concrete translation, English dictionary definition of concrete. Some research work on reducing the cement clinker content in concrete has already been carried out. Weaker than either of the two main components of concrete. Definition: time-dependent deformation due to sustained load.-. Very low-strength—14 MPa (2,000 psi) or less—concrete may be used when the concrete must be lightweight. [126], Currently, there is not a End-of-Waste criteria for concrete materials in the EU. [43], As stated by Abrams' law, a lower water-to-cement ratio yields a stronger, more durable concrete, whereas more water gives a freer-flowing concrete with a higher slump. Its widespread use in many Roman structures, a key event in the history of architecture termed the Roman architectural revolution, freed Roman construction from the restrictions of stone and brick materials. 2- The mould is then placed on a base plate. Many precautions are observed in cold weather placement. [122], Concrete can be damaged by many processes, such as the expansion of corrosion products of the steel reinforcement bars, freezing of trapped water, fire or radiant heat, aggregate expansion, sea water effects, bacterial corrosion, leaching, erosion by fast-flowing water, physical damage and chemical damage (from carbonatation, chlorides, sulfates and distillate water). 200 . Air entrainment admixtures are often used in freeze-thaw climates to minimize the possibility of frost damage.

But the number can not , in easy pronunciation , be extended beyond these . Like other materials timber, steel, stone, aluminum, and composite material; concrete do have its own pros and cons. Mobile sorters and crushers are often installed on construction sites to allow on-site processing. Reinforcement is generally placed in areas of the concrete that are likely to be subject to tension, such as the lower portion of beams. Found inside – Page 170It is quite obvious that the knowledge of such variables as well as the ways in which they can be appropriately modified is of paramount importance to teachers who can take concrete steps with an eye for enhancing pronunciation ... Waste light is form of polymer modified concrete. [80], Nanoconcrete (also spelled "nano concrete"' or "nano-concrete") is a class of materials that contains Portland cement particles that are no greater than 100 μm[81] and particles of silica no greater than 500 μm, which fill voids that would otherwise occur in normal concrete, thereby substantially increasing the material's strength. [113], Concrete roads are more fuel efficient to drive on,[114] more reflective and last significantly longer than other paving surfaces, yet have a much smaller market share than other paving solutions. So it is very important to know definition, types, properties and their uses of concrete. A small region next to the particles of coarse aggregate. Any interruption in pouring the concrete can cause the initially placed material to begin to set before the next batch is added on top. Concrete, an artificial stone-like mass, is the composite material that is created by mixing binding material (cement or lime) along with the aggregate ( sand, gravel, stone, brick chips, etc. The strength of concrete changes (increases) for up to three years. —n. [69] Some other admixtures, especially air-entraining admixture, can increase the slump of a mix. That the deadline was extended to 23 June 2021 for engineering controls in the hydraulic fracturing industry. Hence, to increase its overall strength, steel rods, wires, mesh or cables can be embedded in concrete before it is set. Concrete has relatively high compressive strength, but much lower tensile strength. Rather, it is immediately absorbed by the ground. The extremely high temperatures and long periods of time at those temperatures allows cement kilns to efficiently and completely burn even difficult-to-use fuels. After mixing, concrete is a fluid and can be pumped to the location where needed. Concrete poem synonyms, Concrete poem pronunciation, Concrete poem translation, English dictionary definition of Concrete poem. This could lead to a waste of scarce raw materials such as slag and fly ash. Concrete that is subjected to long-duration forces is prone to creep. Thus, the hydration of cement involves many reactions, often occurring at the same time. Concrete, an artificial stone-like mass, is the composite material that is created by mixing binding material (cement or lime) along with the aggregate ( sand, gravel, stone, brick chips, etc. Concrete 1 Concrete A composite material that consists essentially of a binding medium, such as a mixture of portland ce-ment and water, within which are embedded parti-clesorfragmentsofaggregate,usuallyacombination of fine and coarse aggregate. Site-poured concrete is also known as in-situ concrete or cast-in-place concrete. Concrete - Definition Properties and Classification Cement concrete is a mixture of cement, sand, pebbles, or crushed rock and water which, when placed in the skeleton forms followed by curing becomes hard like a stone. [17] Concrete was used for construction in many ancient structures. Polymer concretes are frequently used for the repair and construction of other applications, such as drains. [20] The Colosseum in Rome was built largely of concrete, and the concrete dome of the Pantheon is the world's largest unreinforced concrete dome. Care must be taken in the placement method to prevent washing out the cement. From North America's leading language experts, Merriam-Webster The amount of concrete used in the construction of the dam is estimated at 16 million cubic meters over 17 years. The manufacture and use of concrete produce a wide range of environmental, economic and social impacts. Concrete is by far the most versatile and most widely used construction material worldwide. This surpassed the previous record by 50% in total volume and 7.5% in total area. [144], This article is about the construction material. The elasticity of concrete is relatively constant at low stress levels but starts decreasing at higher stress levels as matrix cracking develops. [42], Combining water with a cementitious material forms a cement paste by the process of hydration. The cement paste premix may include admixtures such as accelerators or retarders, superplasticizers, pigments, or silica fume. From the 11th century, the increased use of stone in church and castle construction led to an increased demand for mortar. Examples of improved appearance include stamped concrete where the wet concrete has a pattern impressed on the surface, to give a paved, cobbled or brick-like effect, and may be accompanied with coloration. As the name suggests, a slab is a single layer of concrete, several inches thick. Concrete is a well-known and widely used construction material. https://en.wiktionary.org/w/index.php?title=concrete&oldid=64307934, Requests for review of Indonesian translations, Terms with redundant transliterations/jje, Creative Commons Attribution-ShareAlike License. Concrete definition. CS1 maint: DOI inactive as of October 2021 (. An undesirable gradation can mean using a large aggregate that is too large for the size of the formwork, or which has too few smaller aggregate grades to serve to fill the gaps between the larger grades, or using too little or too much sand for the same reason, or using too little water, or too much cement, or even using jagged crushed stone instead of smoother round aggregate such as pebbles. Pervious concrete also permits rainwater to filter through roads and parking lots, to recharge aquifers, instead of contributing to runoff and flooding.[84]. In other situations, specific processing sites are established, which are usually able to produce higher quality aggregate. Cement kilns are extremely large, complex, and inherently dusty industrial installations, and have emissions which must be controlled. Found inside – Page 13Factor 4 shows that motivational factors include a sense of enjoyment in performing the task of pronunciation learning ... Learners may not have a systematic and concrete perception of what it is nor how to improve their pronunciation ... noun. [140] The previous record, 13,200 cubic meters poured in 54 hours despite a severe tropical storm requiring the site to be covered with tarpaulins to allow work to continue, was achieved in 1992 by joint Japanese and South Korean consortiums Hazama Corporation and the Samsung C&T Corporation for the construction of the Petronas Towers in Kuala Lumpur, Malaysia. Concretene is very similar to concrete except that during the cement-mixing process, a small amount of graphene (< 0.5% by weight) is added. The terms asphalt (or asphaltic) concrete, bituminous asphalt concrete, and bituminous mixture are typically used only in engineering and construction documents, which define concrete as any composite material composed of mineral aggregate adhered with a binder. On average, every tonne of cement produced releases one tonne of CO2 into the atmosphere. The first concrete reinforced bridge was designed and built by Joseph Monier in 1875.[38]. All the other applications would fall under the category of downcycling. had the concrete evidence needed to convict. [34] Aspdin chose the name for its similarity to Portland stone, which was quarried on the Isle of Portland in Dorset, England. One of these methods includes placing the cone on the narrow end and observing how the mix flows through the cone while it is gradually lifted. They are used as supplementary cementitious materials (SCM) or as aggregates for cements and concretes. [92] Lightweight concrete is often achieved by adding air, foams, or lightweight aggregates, with the side effect that the strength is reduced. Found inside – Page 22The pronunciation of some words may depend on the concrete synthetic voice (certain pronunciation peculiarities have to be recorded somewhat differently for different synthetic voices) and the pronunciation of separate words may differ ... [9] Often, additives (such as pozzolans or superplasticizers) are included in the mixture to improve the physical properties of the wet mix or the finished material.

Words and phrases like "102 degrees," "obese Siamese cat," and "deep spruce green" are concrete. [23] However, due to the absence of reinforcement, its tensile strength was far lower than modern reinforced concrete, and its mode of application also differed:[24], Modern structural concrete differs from Roman concrete in two important details. [96] The overall embodied energy of concrete at roughly 1 to 1.5 megajoules per kilogram is therefore lower than for most structural and construction materials.[97]. However, it has little impact on reducing greenhouse gas emissions as most emissions occur when cement is made, and cement alone cannot be recycled. Structures made of concrete can have a long service life. Define concrete. The use of an aggregate blend with an undesirable gradation[citation needed] can result in a very harsh mix design with a very low slump, which cannot readily be made more workable by addition of reasonable amounts of water. A concrete made from a mixture of lime, sand, and gravel is said to be as lime concrete. Besides creating pressure through osmosis and crystallisation, deicing chemicals increase the degree of concrete saturation and keep concrete pores at or near maximum fluid saturation, thus increasing the risk of frost damage (Litvan 1976). Portland cement is the commonly used type of cement for production of concrete. Pumping aids improve pumpability, thicken the paste and reduce separation and bleeding. Workability can also be measured by the flow table test. High-flow concrete, like self-consolidating concrete, is tested by other flow-measuring methods.

The binder must fill the gaps between the aggregate as well as paste the surfaces of the aggregate together, and is typically the most expensive component. Concrete dust released by building demolition and natural disasters can be a major source of dangerous air pollution. The paste, composed of portland cement and water, coats the surface of the fine and coarse aggregates. Furthermore, it is generally cheaper to obtain than virgin material.[122]. These developments are ever growing in relevance to minimize the impacts caused by cement use, notorious for being one of the largest producers (at about 5 to 10%) of global greenhouse gas emissions. Definition and synonyms of concrete from the online English dictionary from Macmillan Education. Another major benefit is that pervious concrete can be used, which eliminates the need to place storm drains near the road, and reducing the need for slightly sloped roadway to help rainwater to run off. [31], The Canal du Midi was built using concrete in 1670. Did you know? The presence of some substances in concrete, including useful and unwanted additives, can cause health concerns due to toxicity and radioactivity. The slab is poured thicker at the edges, to form an integral footing; reinforcing rods strengthen the thickened edge. Upon curing, this placement allows the 50,180-square-foot (4,662 m2) cofferdam to be dewatered approximately 26 feet (7.9 m) below sea level to allow the construction of the Inner Harbor Navigation Canal Sill & Monolith Project to be completed in the dry. Especially long-living, durable, energy-intensive building materials, such as concrete, can be kept in the life-cycle longer through recycling. Found inside – Page 4456): Children will need to recognize the sounds and units of a language even if, for example, the concrete pronunciation will differ from speaker to speaker and even situ- ation to situation. Third, children need to be able to recognize ... A common technique involves heating the poured concrete with steam, which serves to both keep it damp and raise the temperature so that the hydration process proceeds more quickly and more thoroughly. CSHub's Executive Director Jeremy Gregory, however, sees concrete's scale as an opportunity to mitigate climate change. The concrete solidifies and hardens through a chemical process called hydration. For most routine uses, 20 to 32 MPa (2,900 to 4,600 psi) concrete is often used. Modern concrete wall systems use both external insulation and thermal mass to create an energy-efficient building. It can For example, the lower floor columns of high-rise concrete buildings may use concrete of 80 MPa (11,600 psi) or more, to keep the size of the columns small. 100 Concrete Noun Examples, Definition and Examples Concrete Noun There two types of things in the universe. While concrete is likely to remain important in applications where the environment is challenging, novel, smarter and more adaptable materials are also needed.[8]. [98] Concrete walls leak air far less than those made of wood frames. The size distribution of the aggregate determines how much binder is required. First, its mix consistency is fluid and homogeneous, allowing it to be poured into forms rather than requiring hand-layering together with the placement of aggregate, which, in Roman practice, often consisted of rubble. Through a chemical reaction called hydration, the paste hardens and gains strength to form the rock-like mass known as concrete. Cement paste, most commonly made of Portland cement, is the most prevalent kind of concrete binder. Raising the water content or adding chemical admixtures increases concrete workability. The term ''concrete language'' gives a clue to the concrete words definition. Improper curing can cause scaling, reduced strength, poor abrasion resistance and cracking. AnonymousUnfortunately, I had sent my email with the phrase "concrete response" before I had the chance to read your post.Do you think asking for a "concrete response" was offensive? Concrete is sometimes used as a fire protection for steel frames, for the same effect as above. [25], The long-term durability of Roman concrete structures has been found to be due to its use of pyroclastic (volcanic) rock and ash, whereby the crystallization of strätlingite (a specific and complex calcium aluminosilicate hydrate)[26] and the coalescence of this and similar calcium–aluminum-silicate–hydrate cementing binders helped give the concrete a greater degree of fracture resistance even in seismically active environments.
