Transcript of Buiding Materials[1]
Building Materials:
1. Building Materials:
Materials used in construction:
Petreous materials, Biender materials, Concrete, Ceramic materials and Others.
Construction of buildings:
Seven steps.
Materials used in construction:
Petreous materials: materials that are made of stone. Types:
>Compact stones:blocks oflimestone, granite, marble...
>Disgragated stones: fragments of stones such as arids and clays. There are two types: fine and coarse.
>Petreous materials:
Materials used in construction:
Biender materials: materials that mixed with water become pasty and when they solidificate they acquire stiffness.
>Lime: it comes from limestone.>Gypsum: with water, it is used to cover walls
and roofs.>Cement: it is the most used biender material.
>Biender Materials:
Materials used in construction:
Concrete: it is a mixture of arids, bienders and water.
>Mass: formed by water, cement and sand.>Cyclopean: formed by cement, water and
very big arids.>Cellular: it has bubbles inside, so that they
are lightier and better termic insulator.>Reinforced: it has bars of steel inside, so
that they are stronger.
>Concrete materials:
Materials used in construction:
Ceramic materials: they are pieces of clay baked in ovens.
>Bricks: they have prismatic forms and holes.>Roof tiles: used in roofs.>Tiles: square shaped pieces used in
bathrooms and kitchens.>Porcelain: it is used for bathroom's
sanitaries.>Stoneware: made of clay, quartz and
feldspar, it is used in roofs and walls.
>Ceramic materials:
Materials used in construction:
Other materials:>Metals: the most used are: -Steel: used for reinforced concrete. -Aluminium: for doors, windows... -Copper: instalations of water, gas and
heating.>Wooden: used in roofs, doors, windows,
floor...>Plastic: artificial materials used in plumbs,
cables, windows, flooring, enclosures...>Glass: in windows, doors, decoration...
>Other materials:
Construction of buildings:
1.-Preparation of terrain:By demolition, earth moving and leveling.The used machines are heavy machinery.
Construction of buildings:
2.-Foundation: Placement of the elements that hold up the
building. They are made of mass and reinforced concrete. There are three types: zapatas, pilotes and losas. By excavators and cranes.
Construction of buildings:
3.-Structure: The pillars and the forges are constructed.
Pillars are made of reinforced concrete. The forges are made of beams and vaults. Machinery: cranes.
Construction of buildings:
4.- Roofing: It is the placement of the roof of the building.
It depends on the climate of each place. It has insulations. There are 2 types:
mixed roof tile and arabic roof tile.
Construction of buildings:
5.-Cladding:It consists of the exteriorm wall of the building.
It is made of bricks and a termic and acoustic insulators, called polyurethane
foam.
Construcion of buildings:
6.- Flooring and cloison:-Cloison is to separe the rooms. The walls are
not as thick as in cladding. Itis made of bricks and plasterboard.
-Flooring is the floor of the different rooms. Types of flooring:
-terrazzo, marble, wood, granite, stone, synthetic, laminated and sandstones.
Flooring and cloison:
Construction of buildings:
7.- Finishing and other facilities:>Finishing:-exterior: marble facings, peinture, mortars..-interior: peinture, limestone, furniture...
>Other facilities:-plumbing, heating, electrical, air conditioning,
alarms and intercorms, tv, radio, telephone, internet and others.
