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.
The construction of a building is virtually incomplete without reinforcement. In construction, Steel is the primary alloy used for reinforcement. There is a reason for that because as we know that concrete is used for the construction of the building, even though it provides the compressive strength, it has weak tensile strength for withstanding induced forces. Therefore by combining reinforced bars, it provides the tensile strength for concrete to withstand induced forces. Also, The properties of thermal expansion for both steel and concrete are approximately the same which is why steel is used as reinforcement.
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.
Steelmaking is one of the most important processes in the industrial sector all over the world. Steelmaking results in the production of steel from iron ores, which is used for a variety of purposes ranging from construction of roads, railways, infrastructures, automobiles and buildings. Even the most innovated TMT reinforced steel bars like the Fe 415, Fe 500 etc are developed from the steelmaking process. The demands for steel are always increasing to the point that we cannot imagine a world without steel.
Thermo Mechanically Treated (TMT) reinforced steel bars are the backbone of building structures. They offer the right amount of tensile strength and ductility needed for withstanding the different types of loads of the structure. Since it is an inevitable factor in the construction field, there are many steel companies in India which produce TMT reinforced bars.
Steel is the most widely used material in the construction field. Being an alloy of Iron, Carbon, it is known for its high tensile strength and low cost. Before the inclusion of steel, concrete was solely used for building structures but the catch was that concrete could only deal with the compressive strength of the structure and couldn’t deal with the tensile strength. This situation was quite a challenge to overcome until the introduction of reinforcement.
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.
