Types of Building Materials, their Properties and Uses in Construction Works Building material is any material which is used for a construction purpose. Many naturally occurring substances, such as clay, sand, wood and rocks, even twigs and leaves have been used to construct buildings. Apart from naturally occurring materials, many man-made products are in use, some more and some less synthetic. The manufacture 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, plumbing, roofing and insulation work.
Steels are widely used materials in the industry. The carbon present in the form of iron-carbide Fe3C increases the hardness and strength of the steel. Based on Method of manufacturing of steels, they are classified as Bessemer steel method and Electric Arc Furnace method whose explanation is below.
The principle of Bessemer Converter is the removal of impurities from the iron by oxidation and the air is being blown through the molten iron. The impurities manganese mn and Silicon Si are converted into their respective oxides and that can be expelled out. It is an extremely hot enclosed region, where heat is produced employing electrodes for melting certain materials such as steel scrap without changing the electrochemical properties of the material metal.
The electric arc produced between the electrodes and the metal is used for melting the metal scrap. Read more: Bessemer steel method and Electric Arc Furnace method. These are mainly used for making Tools and Dies for cutting, forming and forging metals in their hot or cold conditions.

A material's property or material property is an intensive property of some material , i. These quantitative properties may be used as a metric by which the benefits of one material versus another can be compared, thereby aiding in materials selection. A property may be a constant or may be a function of one or more independent variables , such as temperature. Materials properties often vary to some degree according to the direction in the material in which they are measured, a condition referred to as anisotropy. Materials properties that relate to different physical phenomena often behave linearly or approximately so in a given operating range [ further explanation needed ].
Sales Contacts. By: Dave Olsen. The mechanical and physical properties of materials are determined by their chemical composition and their internal structure, like grain size or crystal structure.
Matter is anything that has mass and occupies space. A useful way to start thinking about matter is to think about the different materials, or substances, that it can be made into. These materials make up the objects around us, and each of these materials has different properties or characteristics that can be observed or tested.
A material is a substance or mixture of substances that constitutes an object. Materials can be pure or impure, living or non-living matter. Materials can be classified based on their physical and chemical properties , or on their geological origin or biological function. Materials science is the study of materials and their applications.
This section introduces the meaning of each of the following physical properties and, where applicable, their units of measurement. It is likely that the teaching of this and the first topic Mechanical properties of materials will overlap. Most of these are probably more familiar from KS4 teaching than the technical terms applying to mechanical properties, although a more mathematical approach is needed. One of the many excellent simulations available from PhET at the University of Colorado, this activity allows students to change mass, volume and density, then observe the effect on an object in water. Relationships are explored and explained clearly by the observable changes.
