Choice of Material for luxury buildings

Choice of Material for a luxury buildings


Which material can be used to the best luxury advantage for a particular part of the building, depends as well on the kind of load to which it is subjected and on the-shape of the part.
That the development of the metallurgical and machine build ing industry made possible mass production of prefabricated large size concretjend peinforced-concrete structural elements
is a well known factor to influence the choice of materials.Reinforced concrete is a building material in which the joint functions of concrete and steelare advantageously utilized. Being brittle, concrete cannot withstand tensile stresses, and it cannot therefore be used in structures subjected to tensile stresses under load. But if steel is introduced into concrete it changes the property of the monolith.There are two kinds of reinforced concrete: with or dinary reinforcement and concrete with prestressed reinforce ment. To reinforce ordinary concrete structures is to intro duce steel rods in stretched zones of concrete elements. Reinforced concrete structures and elements are widely used both for residential houses and industrial buildings.
In many cases bricks too are very satisfactory for use in the luxury construction. Bricks generally present a pleasing appearance and can be obtained with various qualities, colours, and textures. Being of a high volume weight and high thermal conductivity, ordinary brick is not always satisfactory in building practice. There are other kinds of bricks which are more effective, they are light-weight building bricks, hollow or porous bricks. Light weight building bricks differ from ordinary clay bricks in a lower volume weight and lower thermal conductivity, and are therefore more economical than ordinary bricks. One of the most significant facts about both industry and building has been research on synthetics and plastics, Plastics have appeared comparatively recently but, owing to their inherent valuable and diverse properties, have found a wide application in many industrial fields (machine-building, aviation, textile industry, etc.). In respect to physical and mechanical properties at a normal temperature of 20°C all plastics are divided into rigid, semi-rigid, soft and plastic. In respect to the number of constituents plastics may be classified as simple and complex. Plastics consisting of one polymer are referred to as simple. Thus, organic glass (plexiglass) consists of one synthetic resin. But in the building field we usually deal with complex plastics, e.g. plastics consisting of a polymer and other components.
