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.
Use of Thermo Mechanically Treated (TMT) reinforced bars for construction is now a standard practice. With newer technologies developing, it results in efficient constructions strategies which in turn improves the lifespan and structural integrity of the building structure. However strong the building structure claims to be, in order to for its longevity the building structure has to face several hurdles, even the natural disasters.
TMT Bars And Their Influence
TMT bars have become the backbone of every civil construction out there, they can give structures shapes, strength, and they can be moulded to make slabs, beams and columns as well.
As the expectations and demands of the common man rise with respect to make real estate structures. The need for high-quality materials for building structures has also gone, and this is one of the reasons why TMT bars have taken the centre stage in the construction field. TMT bars come in different grades so as to cater to different needs. These TMT bars have the approval of the Bureau of Indian Standards for building and construction projects. While Fe 415 is the popular choice among homeowners, Fe 500 and Fe 500D have carved out a market for themselves. In the blog, we will take a look Fe 500 and Fe 500D, just like Fe 415 they too are popular with a section of architects and engineers.
When the word corrosion pops up, we think of corrosion of metals due is to constant interaction with air (much more specifically oxygen), corrosion is the process of the metal actually becoming stable than its refined state. The corrosion we are discussing here is entirely different, galvanic corrosion occurs when 2 metal is in contact for a long duration of time. This happens due to the fact that different metals have different electrochemical properties. The metals act as anode and cathode and the process of stabilizing the metals start, meaning by which is corrosion.
The TMT in TMT Bars stand for Thermo-Mechanically Treated, it is a process of rapidly cooling down bars in the molten state. This cooling down process is either done spraying water at regular intervals. This regular interval will further define the characteristics of the bars. This interval of quenching of bars will give rise to different grades of TMT bars in fact. The goal here is to have a solid and hard outer surface with a pliable inner core. This outer shell is coated with a protective film, making them resistant to corrosion and rust, making them apt for constructing sensitive structures such as high rise residential buildings and bridges in humid areas. TMT bars and different Steel Grades.
TMT bars of the same grade usually have more than one type, while it is uncommon to hear about Fe 415D or Fe 415S. One must surely be heard of Fe 500 and Fe 500D, here Fe stands for iron, 500 stands for the tensile strength and D stands for ductility. Other than the names they also have a different chemical composition as well. When talking about carbon content Fe 415 has a maximum per cent 0.30 carbon while Fe 415 D and Fe415 S has a maximum carbon per cent of 0.25.
In this blog we will be taking a close look at Fe 415, the choice of the common man/ woman for building his/her dream home. We will taking a detailed look on how different grades of steel react to different standards tests undertaken by the Government of India. The number 415 in this grade of steel simply refers to its yield strength. Below some of the characteristics by different grades are marked.
A home is dream of the common man, the common man wants a personal space where he or she unwind and relax without a care in the world. So, the common man wants a home which confines to his sense of design, safety and longevity. To meet the expectations and demands of the ever more demanding common man, the construction sector has always been in the business of reassuring people about the quality and safety of their products. Below are some of the individual raw materials which have changed the landscape of the real estate sector india.
With the ever-increasing demand of Steel for the visionary development around the globe, this reliable metal has been undergoing constant up-gradations and newer technologies and processes are being used for its manufacturing. With 1500 types of high-grade Steel available around the globe, there is immense growth seen to fulfill the different requirements Steel can cater to for development and infrastructure for the modern world.
Steel grading is one of the main characteristics used for selection of Steel for the different purposes. These grading systems are developed by National and International Standard organizations to ensure standard categorization and aid selection of Steel for their purpose.
