The Part-I of this blog explained about the two most important factors to be considered in a TMT steel reinforced bar which was Tensile strength and Ductility. Also, a brief introduction of Ductility was described. The hot and soft inner ferrite-pearlite core is responsible for endowing the reinforced bar with optimum ductility. The ductility is not something that should be neglected. It is an integral part of handling the forces or loads of a building structure.
Reinforced steel bars, the supporting platforms in the construction of modern building structures. The current innovation in reinforcement steel is the TMT steel reinforced bars. Known for their unparalleled tensile strength and ductility factor, reinforced steel bars have literally dominated the construction sector in India and all over the world.
Reinforced steel bars have played a major role in the rise of the construction sector by evolving with the demands of the construction sector to provide safer buildings. The use of steel bars as reinforcement started from the 19th century. The rising demands led to the innovation of technologies that refined steel reinforced bars, used for constructing structures.
Part-I of this blog explained the current reinforcement steel trend in India, the TMT steel reinforced bar, the different grades and which grades are preferred. It also explained the most important factor of TMT steel bar which is Ductility. How is it compromised for higher strength. In this blog, the shift towards value-added reinforced steel is explained
Reinforced steel bars or rebars has become the preferred standard for construction of building structures, bridges and many other commercial structures. The most popular among them is the Thermo Mechanically Treated ( TMT) reinforced bars. About 35% of the total steel production in the country was accounted by the reinforced steel industry. Usage of high strength TMT steel rebars has ensured rapid growth within the construction sector.
One of the common news we know through newspapers and televisions is the sudden collapsing of building structures, whether they are structures that have finished constructing or the ones still in the construction phase. Usually, buildings are constructed for long-term sustainability. The irony is that most of the recent building collapses are not caused by any natural disasters.
Iron is one of the most used versatile metal in the world. Normally Iron is found in ores. Iron ores are rocks from which iron is extracted for the purpose of processing iron which in turn is further reformed to produce reinforced steel bars. Iron ores are not pure, they contain elements like Sulfur, Phosphorus, Carbon etc. These elements are present in high percentage which results in brittleness and less tensile strength for the metal.
Steel has been a vital tool for mankind since its inception. Steel is the major component in almost everything starting from buildings, bridges, automobiles to pieces of machinery. Discovery of steel and it’s production dramatically changed the economic status of the world. Steel is an alloy of Iron and Carbon in which the carbon content is at 2% (Above 1%, it is classified as Cast Iron).
