• Steel
There are over 3000 different grades of steel all with unique physical and chemical properties. The production of steel is made in accordance with its application. Due to its high strength Steel is one of the most common materials within the construction industry. The most important properties of steel are density and robustness, good tensile and yield strength, good thermal conductivity and expansion. As well as these important properties, another very important of the stainless steel properties is its resistance to corrode. Steel is often used in the form of beams, columns and plates. Within the construction site steel played a huge part in the development of the project, having several different uses for this …show more content…
Different aggregates can be used to create asphalt which include rock, sand or gravel. In order to bind these aggregates into mixtures a binder is used, commonly a material called bitumen is used. Asphalt road surfaces offer many benefits, including cost efficiency. Asphalt is safe, smooth and durable, it can be built too last indefinitely and is 100% re-useable. One of the main properties of asphalt is its durability, Durability is a measure of how asphalt binder physical properties change with age, this is often called age hardening. Commonly, as an asphalt binder ages, its viscidness increases and it becomes more stiff and brittle. On the construction site asphalt was used in the construction of new roads being built to aid in the congestion of the
