REINFORCING CONCRETE WITH TMT STEEL BARS

REINFORCING CONCRETE WITH TMT STEEL BARS

Though concrete is used everywhere around the globe, you see its looming presence everywhere in India no matter which direction you turn your head and see. Whether it’s a small one-story house or complex, thirty-story IT park structure, the importance of using concrete in building construction to erect a long-lasting structure is vital. 

What is concrete, anyway? It’s a construction material that is a mixture of cement, fine and coarse aggregates, and adequate water. If you leave it, the mixture hardens over a time, providing the sturdy building structure we need. In constructions, concrete is used for laying the foundations, beams, columns, slabs and other structural elements. 

Generally, numerous types of pollutants, such as the form oil used for coating, present in the construction site. These pollutants can lead to the contamination of reinforcement, which ultimately results in considerable bonding and strength issues.  So necessary care must be taken beforehand. 

To avoid problems like these, it’s critical that the two vital elements, steel and concrete, bind well to give the reinforced concrete its raw strength. Your ordinary TMT bars cannot achieve this. Only a quality TMT bar is suitable for the job since they are proven to be a viable method for reinforcing concrete structures from their foundation. When working together, TMT bars can withstand tensile and shear pressures while the concrete resists compressive forces. As a result, the concrete structure became known as Reinforced Cement Concrete (RCC).

RCC has radically changed the face of the construction industry since its inception by becoming the most effective construction material. It has become the most sought-after construction material due to its higher compressive strength and ability to take on any forms and shape. 

WHY REINFORCEMENT IS NEEDED?

Concrete’s compressive strength is extremely strong. Tremendous amount of force is needed to crush it. However, it only requires a minimal force to make a crack on the surface by twisting or bending it. So in order to compensate for the weak tensile strength of concrete, TMT steel bars are incorporated as a support. Additionally, the super elongation property of the TMT bars also takes care of the stress on building and supports the concrete to withstand all kinds of weights.

A concrete reinforcement should not have any impurities like rust, mud, oil paints and so on. It also should be in position to cut, bend, and withstand properly. The good TMT bars from iSteel, one of the best TMT bars manufacturers in Tamil Nadu, always meet these criteria and function as strong reinforcement like the spine does to a human body. 

A reinforcement is always installed and maintained in precise position, allowing superior cover blocks, supporting bars, spacers, laps and so on. It is also placed and fixed in a way it makes the concrete placements easier without compaction and segregation by immersion vibraters.

HOW TMT BARS CAN REINFORCE CONCRETE?

As an irreplaceable reinforcement, TMT bars help concrete to be more resistant to any kind of failures. The following factors, combined or standalone, make TMT bars as a valuable reinforcement to concrete.

1. TMT bars are made to be superior in strength and flexibility. It’s anti-corrosive property and water-cooling prevents the segregation of coarse carbides that is the major cause for the corrosive nature of your regular bar. 
2. The ferrite-pearlite core of TMT bars enables dynamic loading and seismic waves owing to its high ductility property and fatigue resistance.
3. The soft core offers excellent ductility while the tough surface provides top yield strength. 
4. The super strength properties that come with quenching and tempering processes. 
5. Higher weld-ability property that comes with the restricted carbon content of 0.2% 
6. Duality of higher elongation and bendability 

TMT BARS AS EFFECTIVE REINFORCEMENT 

Thermal expansion value of both TMT bars and concrete are more or less the same. Combining with the bendability property, TMT bars can serve as excellent reinforcements

TMT bars can be bonded well with concrete. They are also strong in tension, and can be bent or shaped as well. This helps the concrete to last longer. 

TESTING THE REINFORCEMENT

To test the strength of the reinforcement bar, following tests are performed. 

1. The most common test, the tensile test, is performed where the TMT bar is pressured by the tensile force and elongated to the point of break. This test is performed to determine the tensile strength of TMT bars. 
2. Yield stress tests put the TMT bars under deformation where they cannot be reshaped to the initial shape. 
3. The ductility of the TMT bar is determined by the bend & re-bend tests. In this, the TMT bars are bent to the midpoint of breaking, resulting in bending without a crack. Similarly, the re-bend test measures the aftermath of strain on ageing TMT bar.

WHERE CAN YOU GET THE BEST TMT BARS?

Since there are plenty of TMT bars manufacturers in Tamil Nadu, you must be confused about your choices. But if you choose iSteel, we can guarantee that your dream building structure will last 17% longer as we offer a unique and special composition of steel. Our TMT bars provide excellent reinforcement to the concrete and make the structure resistant to all kinds of stress and loads. The copper used in our steel fills the pores and makes it resistant to corrosion too. No need to worry about rusting. So choose iSteel to build a structure that lasts forever.
