When it comes to constructing a building structure, the right set of resources must be used for ensuring the overall life and the integrity of the building. The introduction of reinforcement in construction improved the overall life expectancy of the structure and made them strong enough to withstand the forces of nature. Steel is the primary component used as reinforcement because of its excellent tensile strength, recyclability and similar thermal coefficient of expansion to that of concrete.
Iron is the most important metal for Industrial purposes.Steel, the most versatile alloy of Iron drastically changed the economic status of the world. Do you know that steel industry can be classified as a Green Industry, but you might wonder how? It’s simple, Recycling.
The previous blog explained about the evolution of steel using different techniques and also how it changed the economic status of the world. Steel is mainly preferred as reinforcements due to their high tensile strength. In earlier times Iron bars was used as reinforcement but it became unsuitable due to formation of corrosion very quickly. It was replaced by Mild Steel (MS) reinforced bar. Even though Mild Steel rebars has good workability, ductility and anti corrosion properties, it has poor bonding with concrete since it’s outer surface is smooth.
