TMT bars, also known as Thermo-Mechanically Treated bars, are a type of reinforcement steel used in construction. These bars are made by passing steel wires through a rolling mill at high temperatures, followed by quenching and tempering. TMT bars are known for their high strength, ductility, and toughness, making them a popular choice for building construction.

One of the key advantages of using TMT bars in building construction is their ability to reduce the amount of steel required for a project. This is because TMT bars have a higher strength-to-weight ratio than traditional reinforcement steel. This means that less steel is required to achieve the same level of strength, which can significantly reduce the carbon footprint of a building project.

Another way that TMT bars can help to reduce CO2 emissions is by reducing the amount of cement required in construction. TMT bars are often used in conjunction with concrete to provide additional strength and durability. However, because TMT bars have a higher strength-to-weight ratio, they can reduce the amount of concrete required in a project. This means that less cement is needed, which can significantly reduce the carbon footprint of a building project.

It’s important to note that not all TMT bars are created equal. When selecting TMT bars for a building project, it’s essential to choose the best TMT bars in India to ensure that the highest quality materials are being used. The quality of TMT bars can vary based on factors such as the manufacturing process, the grade of steel used, and the level of quality control.

Further, when selecting TMT bars for a building project, it’s essential to consider the specific requirements of the project. For example, if the building is located in a seismic zone, it’s essential to choose TMT bars that can withstand seismic forces. Similarly, if the building is located in a coastal area, it’s important to choose TMT bars that can withstand corrosion.

In Kolkata, there are several options for TMT bars. However, when it comes to choosing the best TMT bar in Kolkata, it’s essential to consider the quality and reliability of the manufacturer.

One such manufacturer is Shyam Steel Industries Limited, famous as one of the best primary steel producers in the nation. The organization produces two of the best TMT bars in India. They are Fe 500D & Fe 550D TMT Bars. These TMT bars are made using high-quality steel and undergo a rigorously tested manufacturing process to ensure that it meets the highest standards of quality. Both Fe 500D & Fe 550D TMT Bars are known for their high strength, ductility, and toughness, making them an ideal choice for building construction. 

Let’s walk you through how these two TMT Bars help in bringing down CO2 emissions.

The use of Fe 500D and Fe 550D TMT bars in building construction helps to reduce CO2 emissions in several ways, they are:

• Reduced Steel Consumption: Fe 500D and Fe 550D TMT bars have higher strength and ductility than conventional bars, which means that less steel is required to achieve the same level of strength. This reduces the overall steel consumption in building construction, which in turn reduces the CO2 emissions associated with the production of steel.
• Reduce Transportation Emissions: Fe 500D and Fe 550D TMT bars have higher strength and ductility than conventional bars, which means that they can be manufactured with a smaller diameter. This reduces the weight of the bars, which in turn reduces the transportation emissions associated with their delivery to the construction site.
• Longer Life Span: Fe 500D and Fe 550D TMT bars have a longer life span than conventional bars, which means that they do not need to be replaced as frequently. This reduces the CO2 emissions associated with the production, transportation, and installation of replacement bars.
• Energy-Efficient Buildings: Fe 500D and Fe 550D TMT bars are used in the construction of high-rise buildings and structures, which require less energy for heating and cooling due to their superior thermal properties. This reduces the overall energy consumption of the building, which in turn reduces the CO2 emissions associated with the production and use of energy.

The above processes highlight how the use of TMT Bars ensures a huge reduction of CO2 emissions in buildings, delivering a cleaner and greener environment – providing opportunities for sustainable expansion in the construction industry. 

One of the most important things is picking the best TMT bars in India. They are the foundation of any structure and being unsure of that can put your structure at a big risk. Due to the high demand for top TMT bars in India, there are many manufacturers that claim to offer the best, but it is important to consider various factors before making the pick.

The manufacturing process of TMT bars plays an important role when it comes to finding the best TMT bars in India. The best manufacturers use the latest technologies to make sure the end product has a strong grip, great elongation, and is corrosion and fire-resistant. The bars go through various procedures for the best quality. They undergo quenching, where the hot bars are released from the mill to move into the Thermex System. The water sprays here to cool down the outer core. Next is the Self-tempering step where they are taken out of the box. The heat from the inner layer flows to the outer layer causing a Martensite layer. This is followed by cooling to normal temperatures. As a result, what you get are the top TMT bars in India.

In order to ensure the quality of TMT Bar there are certain tests by which you can ensue it. TMT Bars comes in different grades such as Fe 415, Fe 500, Fe 550, Fe 600, the numbers denotes the yield strength.

Which Grade of TMT Bar is best for Construction?

TMT Bars needs to have the perfect combination between strength & flexibility. As per IS Standards Fe 500d Grade steel reinforcement bars has the perfect combination of strength & flexibility. It is mostly recommended for all type of construction purposes.

However to determine the strength & elongation certain number of tests are performed to ensure its quality. The tests are as follows

• Tensile Test
• Yield Stress Test
• Bend & Rebend Test
• Chemical Analysis Test

What is Tensile Test in TMT Bar?

To measure the strength of reinforcement bars Universal Testing Machine (UTM) is used. Upto 32 mm capacity of TMT Bars can be tested without machine as per IS 1786 and above which need to be tested with it.

Calculation

Determine the cross section area of TMT Re-bar.

• Weight of the Re-bar of 500mm = X mm (b) Length of the Re-bar (Area in mm2 = Weight / Length x 0.00785)

IS: 1786 / 2008 (Clause 6.3.1)

Ultimate Tensile Strength =        

What is Yield Stress Test in TMT Bar?

A Material can take stress upto which level? At which level it will begin to deform plastically? These are factors can be determined during Yield Stress Test/0.2% Proof Stress. Until the material reaches to the yield point it will deform elastically and return to its original shape when the applied stress is removed.

The standard procedure is to project a line parallel to the initial elastic region starting at 0.002 strains. The 0.002 strain point is often referred to as the 0.2% offset strain point.

The behavior of the material can be broadly classified into two categories, brittle and ductile. Steel and aluminum usually fail in the class of ductile materials. Glass and cast iron fall in the class of brittle materials. The two categories can be distinguished by comparing the stress-strain curve.

What is Bend & Rebend Test in TMT Bar?

In many cases you can find that TMT Bars are getting deformed. It happens because of wrong handling of the materials. So, one must be careful while bending and re-bending the TMT at construction sites. When bending or re-bending is done at a construction site, it is to be ensured that the bend radii are not formed below the prescribed minimum sizes in the relevant standards. Incorrect bending can severely affect the performance of steel reinforcement in service.

Important Points to be noted while bending TMT Bars

• Bending should be done gradually & slowly. It needs not to be vibrated while performing it.
• Minimum bend diameters have been established for different bar sizes.
• Bending with pipe of hammer should be strictly prohibited
• TMT Bars should not have dirt/mud in it.

It is essential to select TMT Bars that are manufactured at ISP’s where advanced quenching technologies are used while manufactured. Better tensile strength & elongation comes during the quenching. So BIS Licenses, World Class Quenching Technology such as Thermex these are the main criteria to select the best quality TMT Bars.

Bend Test

The bend test consists of bending a test sample of TMT Re-bar through plastic deformation by applying a load against a suitable mandrel until a specified angle (180 degree) of bend is reached. Depending on the requirements of the material standard such as IS 1786/2008; it should be parallel at a specified distance, an insert is used to control this distance. Test is usually carried out at room temperature and the bending arrangement with two supports (S1 & S2) and a Mandrel (M) has been shown below.

The length (L1) of the test piece depends on the diameter (Φ) of the Re-bar and the Test equipment used. If the distance (L2) between the supports is not specified, then L2 can be calculated as follows:

L2 = Md + 3Φ [Md = Mandrel Diameter]

 The mandrel diameter used for different grades of TMT Re-bar for Bend test are given below as per IS 1786-2008

* Φ is the diameter in mm of the test sample

* : The sample shall be considered to have passed the test if there is no rupture or crack visible at the bend (tension zone) portion to a person of normal vision.

Re Bend Test

This test is designed to measure the effect of strain ageing on the steel. Strain ageing is an embrittlement effect, which occurs after cold deformation, by the diffusion of nitrogen in the steel. The risk of fracture on bending is increased as the temperature is decreased, because these steels have decreasing toughness at lower temperatures. Hence,  temperature parameters should be followed as per code for correct result.

The Re-bend test consists of bending a sample of TMT Re-bar through plastic deformation by applying a load against a suitable mandrel to an included angle of 135 degree. The bend sample should be aged by keeping in boiling water (100 degree C) for 30 minutes and then allowed to cool. The sample should be bent back to have an included angle of 157.5 degree. Test is usually carried out at room temperature. The mandrel diameter used for different grades of TMT Re-bar is given below.

The sample which has been used for bend test is not to be used for Re-bend test.

While applying load on the sample bar it is important to ensure that the load is uniform, smooth and vertically downwards. Impulse load should be avoided.

The specified mandrel diameter used for different grades of TMT Re-bar for Re-bend test are given below as per IS 1786-2008.

* Where Φ is the diameter in mm of the test sample.

* The sample shall be considered to have passed the test if there is no rupture or crack visible at the bend (tension zone) portion to a person of normal vision.

What is Chemical Analysis Test in TMT Bar?

Cross section wise 50mm/60mm length sample cutting from TMT Re-bars by abrasives, grinded and polished one side is used for chemical composition testing in a spectrometer. The spectrometer takes 10 to 15 seconds to give results in printed form of a maximum of 26 elements in the TMT. The spectrometer mainly gives the results of the percentages of carbon, sulphur, and phosphorus which are important as per BIS. In case of micro alloyed grade TMT, percentages of chromium, copper, manganese etc. are also shown by the spectrometer.

The maximum allowable percentages of different elements as mentioned in the IS: 1786-2008 are as below:
