Building material is any material which is used for constructing a building. Many naturally occurring substances, such as clay, sand, wood and rocks, even branches and leaves have been used to develop buildings. Apart from naturally occurring materials, many man-made products are in use, some more and some less artificial. The manufacture of building materials is an established industry in many countries and the use of these materials is usually segmented into specific specialty trades, such as carpentry, plumbing, roofing and insulation job

Concrete:

Concrete is a composite building material made from the mixture of aggregate and a binder such as cement. The concrete is most commonly in the form of Portland cement concrete, which consists of mineral aggregate (generally gravel and sand), Portland cement and water. After mixing, the cement hydrates and finally hardens into a stone-like material. When used in the general sense, this is the material referred to by the term concrete.

Metal:

Metal is used as structural framework for larger buildings such as skyscrapers, or as an outer surface covering. There are many kinds of metals used for building. Steel is a metal alloy whose most important component is iron, and is the usual choice for metal structural building materials. It is strong, flexible, and if sophisticated well and/or treated lasts a long time.

Glass:

Glassmaking is considered an art form as well as an industrialized process or material.

Clear windows have been used since the discovery of glass to cover small openings in a building. They provided humans with the facility to both let light into rooms while at the same time keeping inclement weather outside. Glass is normally made from mixture of sand and silicates, in a very hot fire stove called a kiln. It is usually very brittle. Very often additives are added to the mixture when making to create glass with shades of colors or various characteristics (such as bulletproof glass, or light remittance ).

Plastic:

The term plastics covers a variety of synthetic or semi-synthetic organic condensation or polymerization products that can be molded or extruded into objects or films or fibers. Their name is derived from the fact that in their semi-liquid state they are malleable, or have the material of plasticity. Plastics differ hugely in heat tolerance, hardness, and resiliency. Combined with this flexibility, the general uniformity of composition and lightness of plastics ensures their use in almost all industrial applications today.
