Building materials are materials used for construction purposes. Many naturally occurring substances, such as clay, rocks, sand, wood, and even twigs and leaves, have been used to construct buildings. Apart from naturally occurring materials, many man-made products such as cement, paints, hydrated lime, etc, are in use, some more and some less synthetic. The manufacturing of building materials is an established industry in many countries and the use of these materials is typically segmented into specific specialty trades, such as carpentry, insulation, plumbing, and roofing work. They provide the make-up of habitats and structures including homes.
Various Metals for construction works be broadly classified as ferrous metals and non-ferrous metals. The properties and uses of ferrous metals and some important non-ferrous materials like aluminum and copper are explained here. Ferrous Metals Ferrous material is one in which iron is the main constituent. Iron ore is first converted into pig iron and
Aluminium Aluminium is a chemical element with the symbol Al and its atomic number is 13. It is present on the surface of the earth’s crust in most of the rocks and clay. But to produce the metal bauxite (Al2O3. 2H2O) is ideally suited ore. Properties of Aluminium Uses of Aluminium Copper It is a naturally
