Building materials <ul><li>Building material is any material which is used for a construction purpose. </li></ul>
Stone Materials <ul><li>There are natural stones, can occur in the form of blocks, slabs, granules.
Compact rocks:There are blocks of limestone, marble,granite, slate, sandstone and they are call ashlar, rubble, cobblestones and slabs.
Desintegrated rocks: It is a set of stones of varying size. They are mainly small. Types:
Sand is a naturally occurring granular material composed of finely divided rock and mineral particles.
Clay is a naturally occurring material composed primarily of fine-grained minerals </li></ul>
Binder materials binder materials Is called caking material capable of uniting fragments of one or more material and give cohesion to the set through chemical changes in its mass produce new compounds.
<ul><li>Binder materials </li></ul><ul><li>Lime: It is a material obtained by subjecting limestone to heat.
Plaster:It is a mineral in form of dust used to cover walls and ceilings.
Cement:It is the mos important binder. </li></ul>
<ul><li>Concrete </li></ul><ul><li>It is a mixture of aggregates, binders and water.
There are different types: Mass concrete,cyclopean concrete,aerated concrete,reinforced concrete. </li></ul>
<ul><li>Concrete </li></ul><ul><li>Mass concrete:It´s obtained by mixing cement, water, gravel and sand
Cyclopean concrete: Made up of cement, water, aggregates.
Glazed ceramic:Rectangular pieces made up of two layers.
Stoneware: Mixture of clay, quartz and feldspar.
Porcelain:Ceramic material coated with enamel. </li></ul>
Metal is called the chemical elements characterized by being good conductors of heat and electricity, have high density, and are solid at normal temperatures (except mercury Metals are materials obtained from minerals that are part of the rocks . The most iportnt metals materials are: steel, aluminum and copper Metal materials
Phases of building construction 1.Land preparation 2.Foundation Pile 3.Structure 4.Covered 5. Enclosures 6.Flooring and cloisonne
Land preparation Is consist of ó smooth, demolishing, excavating, leveling the ground ... to build on it
Foundation pile is the placement of the elements that form the base of the building
Structures used columns, slabs that form the floors of the building
Covered involves placing tiles, slabs, etc .... to protect the building from rain, wind ...
Enclosures is to isolate the building with brick exterior, polyurethane foam insulation work.
Flooring and cloisonne is wrought with different coating materials, natural or synthetic
