Expanded polystyrene used as a piece of entrebigat ceilings unidirectional or bidirectional block l

Expanded polystyrene, which is called in shorthand "EPS" English acronym "Expanded Polystyrene" is a material well known by the agents of the building, due to the different functions performed, especially in the field termohigromètric as thermal insulation material. Also a material widely used in the packaging of electronics and food products mineral oil (fruit and vegetables), due to its light weight and its ability to cushion the blows. But not so well known application of expanded polystyrene "EPS" as part of entrebigat mineral oil in the field of relief the roofs of the structures of the building, due to having strong mineral oil presence in our country curved ceramic and concrete blocks relief.
Expanded polystyrene used as a piece of entrebigat ceilings unidirectional or bidirectional block lost roofs (reticular), contributes to model the rugged section of a roof, but in a lighter than do the curved ceramic blocks relief of concrete and it has its advantages as you can see in this article that briefly describes issues to consider, as well as its drawbacks and therefore dealing with a critical use of polystyrene expanded (EPS) as the sole relief ceilings unidirectional and bidirectional concrete used in the construction sector
We understand the relief liviana do something more or less heavy loads or pulling her weight and in the case of structures is based on reducing its own weight. The dead weight of a building represents approximately 50% of the total load on the structures and heavier own weight exceeds 50% of the total burden.
Usually several mineral oil sites can be a structure which can be relieved, however, and ignoring the fundamentals, the site of framed structures used in construction, where relief is most needed is in its horizontal part which is part of the structure that has the mission of covering spaces and in the case of building roofs and decks are.
Throughout history man has always sought to relieve mineral oil the buildings. The first hominids inhabited already used as a shelter, lignite, covered with skins, dismounting and moved from one place to another. From the trouble first buildings to this day, the man always need buildings LIGHT. In the northern parts of the world, man has used wood as a construction material for buildings while the other man used a more massive construction that used stone, ceramics and adobe .
Whether a building tradition as another man has always mineral oil wanted and need to lighten the constructive elements that shape and structure. This has been given to the needs of man built buildings where lights were necessary to cover increasingly important buildings and lifted higher. This has always led to man's search for constructive solutions and ingenious building materials Livian that allow for building more and more impressive. Clear examples of this are the Gothic cathedrals or lightened vaults which are the shining example that represents the Pantheon in Rome was built by Agrippa in 27 BC frame covered with a lap of 43.30 m. inner diameter, lightweight and made with niches inside a mortar pumice and volcanic slag.
Structures lightened basically for three reasons.; For a technical reason based on the need to cover the same surface using a smaller amount of mass. This provides more design freedom in the placement of pillars, a lower degree of effort on the structural elements most requested and less strain on the ceilings. An economic reason as a result of that lighten structures mineral oil reduces the consumption of materials with a higher cost as steel, while maintaining functional conditions, aesthetic and necessary security. This factor is important as it has to cover more surface area and more importantly the lights are still very relevant to cover in very small structures. For one reason because to alleviate environmental structures obtained reduce the production of CO2 required to form materials that are used in building structures as steel.
