  • 1. Building Materials By: Beatriz Aguilar Janita & Juan Manuel Donaire Felipe
  • 2. MATERIALS USED IN CONSTRUCTION
    • Materials of construction are thoose which are used in the construction of buildings.
    • Rock Materials:
    • Compact rocks : Are stone blocks of differents materials like limestone and granite that form paving stones, flagstones,...
    • Separated rocks : Stone fragments with a variable size. - Clay: Very small grains that absorbe water. -Arids:Are fragments of other rocks: Sand and gravel.
  • 3. Binder materials
    • Binders are materials that, if they are mixed with water they become pasty. And when they solidificate they adquire rigidity.
    • Gypsum: It is a mineral that mixed with water it is used to cover walls.
  • 4. Binder materials (II)
    • Lime: It is obtained by the heating of limestone.
    • Cement: It is the most used binder. There are various kinds of cement like: -Iron and steel -Portland...
  • 5. Concrete
    • The concrete is a combination of binder, arids and water.
    • Cellular concrete It is produced by the addition of air inside it.
    • Lime concrete; It is a type of concrete where the cement is repleced by lime.
  • 6. Concrete (II)
    • Reinforced concrete: It is a type of concrete usually strengthened with iron bars.
    • Glass concrete: It´s a type of concrete made with recycled glass. It has a better long term strength and better thermal insulation due to its better thermal properties of the glass aggregates
  • 7. Pottery Materials
    • Pottery materials are pieces fabricated with clay fired in a kiln.
    • The process to elaborate pottery materials have two parts:
    • 1. Some machines mix clay with water, then the mass is passed through different kinds of nozzles.
    • 2. The material cross several rooms with different temperatures.
  • 8. Pottery Products
    • Bricks: Pieces of fired clay. There are two types:
    • Thin bricks: have a good atmospheric resistant and insulating properties. It is used to make facades
    • Normal bricks: they have less resistance . Are used in walls.
  • 9. Pottery Products (II)
    • Tile: Fired clay pieces used in roofs.
    • Glazed tile: Pieces formed by two layers, one of clay and the other of glass. They are use to recover walls in the kitchen and bathroom.
  • 10. Pottery Products (III)
    • Stoneware: Is a mixture used to elaborate glass pottery pieces which are used to make floors and walls.
    • Porcelain: Pottery material covered with enamel that gives to it a glass appearance.
  • 11. Other Materials
    • Steel: Is used to reinforce the concrete.
    • Glass: Is used in lots of types of windows, doors, decorations...
    • Copper: Is used in installations of water, gas...
  • 12. Other Materials (II)
    • Aluminum: Used in sides of windows, doors...
    • Woods: Used in roofs, doors, windows, floors...
    • Plastics: Used like an insulating material, recovering of the floors, windows...
  • 13. Building construction
    • The builiding construction has several phases.
    • 1. Prepare the terrain through several actions.
    • 2. Positioning of the elements which are undergound andgenerally are made of reinforced concrete.
    • 3. Rising of the structure.
  • 14. Building Construction (II)
    • 4.It´s the covering of the builiding.
    • 5.Materials like wood, stoneware... are used over each floor.
    • 6.Through the rising of walls rooms are builded.
    • 7. Placing of several instalations like water or electricity ones.
    • 8.It´s the final phase of the building, in which the use of the building is determinated.
  • 15. Construction Machinery
    • In the excavation are used diggers.
    • In the leveling of the terrain are used bulldozers, steamrollers...
    • The materials are transported in lorries.
  • 16. Construction Machinery (II)
    • The materials are elevated with cranes, which are formed by three elements:
    • 1. A vertical metallic structure.
    • 2. A horizontal metallic structure which can turn 360º.
    • 3. Structure that support the load.
  • 17. Enviromental Impact
    • Human Beings live a great part of their lives inside buildings. In Europe around the 40% of the energy is used in construction.
    • The enviromnental impact is due to various factors:
    • A building has a long life.
    • It interfere with nature.
    • A building is very complex and has a great quantity of materials.
