Concrete is a construction material consisting of cement (usually Portland cement), sand, stones as well as water. The mixing ratio is expressed as weight proportions of first three concrete color pigment ingredients. The amount of water is used to adjust the volume - less water results in higher binding strength. As a building material it excels by being malleable during molding, having high compressive strength after curing and good weather resistance.
The great progress in the scientific study of the behavior of reinforced concretes and technological advances enabled the construction of large dams and tall skyscrapers. Its role is now irreplaceable in public buildings, including stadiums, theaters, cinemas, etc. Many nations and cities compete to erect a larger building that is more beautiful, as a symbol of progress that normally will be made of reinforced slabs.
There are no signs of its use found until the thirteenth century, when it was reused in the foundation of Salisbury Cathedral and the famous Tower of London, England. During the Renaissance, its use was low and not significant. In some cities, large structures built by Mayans and Aztecs in Mexico or Machu Pichu in Peru used cement.
The variety of concretes that have emerged around the late twentieth century, has been allowed to exist: concrete reinforced with glass fibers (GRC), cellular concretes lightened with natural, self-compacting fibers. The history of this material represents an essential chapter in the history of building construction. When it was decided to construct buildings using clay or stone materials, it became necessary to obtain pastes or mortars that allow attaching said to form stable masonry structures.
Concretes by their stone characteristics withstand compression forces, and other types of cracking stress (bending, tension, torsion, shearing); inclusion of metal rods optimize their characteristics and their widespread use in many engineering and architecture projects. The world's tallest buildings have steel structures, such as the Petronas Towers in Kuala Lumpur, Malaysia (452 meters, 1998), the Taipei 101 in Taiwan (509 meters, 2004), or the Burj Dubai city of Dubai (818 meters, 2009), in the XXI century.
Without the participation of an aggregate it is called mortar. Concretes are produced with other binders which are cement, asphalt concrete and bitumen used for mixing. Cement is a powdery material that by itself is not binding, and when mixed with water, the hydrate becomes a moldable paste with adhesive properties.
It hardens in a few hours turning to a stone material. The cement consists essentially of hydrated calcium silicate (SCH), this compound is mainly responsible for its adhesive properties. It is called hydraulic cement when it is formed from hydration, it is stable under aqueous environment. In addition, you can modify some of its characteristics or behavior by adding additives (in amounts less than 1 percent of the total mass).
Among them, the most important is the nuclear reactor that collapsed in the Chernobyl plant, which was covered with concrete to prevent radiation leaks. Concrete is the material resulting aggregates unite with paste obtained by adding water to a conglomerante. The binder can be any, but when we refer to concrete, usually is an artificial cement, and between them, the most important. Aggregates come from the disintegration or grinding, natural or artificial rocks and, according to the nature thereof, are called siliceous aggregates, limestone, granite, etc. The aggregate whose size is greater than 5 mm is called coarse or gravel, whereas less than 5 mm is called arena.
