There is no single accepted definition of what represents the material in the construction industry. Building material is a material used for construction.
Many naturally occurring substances are used for building construction, such as clay, rock, sand, etc., apart from naturally occurring substances, some manufactured products are also used, which are more or less synthetic. Construction material means an article or material brought to the construction site by the contractor or the sub-contractor for integration into the building or work. The material used for building a structure is called construction material. Natural material (Stones, Timber, Lime, Soil), Artificial material (Bricks, Cement, Artificial Sand, Precast concrete products, Particle board), Special material (Artificial Material, Geo-synthetic Material, Fibre, Recycled Material), Finishing material (Plaster of Paris, Mortar, Paints, Wall Cladding, Tiles).
Factors affecting Construction materials are Aesthetically Pleasing, Prescribed load, Economical, Eco-Friendly, Serviceability, and Durability.
Aesthetically Pleasing: The material used should have a pleasurable taste, smell, appearance, touch, vision, etc. it should also be pleasurable for our emotions, commodity, etc.
On the basis of Load carrying capacity: The material should have more than enough strength to carry the calculated load.
Economically: The construction material should be economical for the transportation cost. The heavier the metal greater the transport cost of the material.
Eco-Friendly: The construction material should be eco-friendly, they should not have leakages of gas or chemical, toxic, irritating, hazardous compounds which may harm the environment.
Construction materials have numerous properties that make them suitable for various applications. Some of the applications include resistance to fire, water, and pests. It also provides Stiffness, durability, and strength. All materials have different properties, so choosing the suitable material for the job is necessary. Construction materials are well-designed to withstand various loads and stresses. Strength is the ability of the material to prevent other forces from breaking it. When force is applied, Stiffness is the ability of the material which helps to resist deformation. The toughness of the material helps to absorb energy without breaking the material. The durability of the material reduces wear and tear of the material.
Example: As concrete is strong and durable, it is not stiff, so it is unsuitable for building bridges. But on the other hand, steel is significantly stiffer than concrete, so it can be used for building a bridge.
Leading key player in the construction material industries is Holcim Group, Cement Roadstone Holdings, Vulcan Materials, etc.
