Application:
In addition to the strength and ductility requirements, reinforce concrete needs adequate bonding between steel and concrete to ensure the composite works efficiently. This perfect bonding is essential for those applications where structures are subject to unexpected forces like seismic, dynamic, impact etc. Therefore, these are widely used in concrete reinforcement structures like bridges, flyovers, dams, thermal and hydel plants, industrial towers, skyline buildings, underground platforms etc. Throughout the making of this next generation double rib TMT bars, each process is highly focused upon so as to not compromise on its quality at any cost, at any stage.

Features:
Kamdhenu Nxt is called the product of the next generation because it has the characteristics to meet the requirements of the new engineered reinforcement structures and smart architectural concepts. The vital features of this high end interlock steel TMT bar are as follows:

• Exclusive double rib design: For a stronger interlock bond
• 2.5 times stronger concrete-steel interlock (ratio of load/bond strength) : To give more strength to the structure
• Advanced earthquake resistance: Ensuring the safety and security of the building and structure
• Superior thermal resistance: To resist the heat flow in the constructed building
• Better corrosion resistance: To guarantee longer life span of interlock steel TMT bar due to good anti-corrosion qualities
• High ductile strength: To make certain unbreakable flexibility assuring better application
• Extensive application range: Right chemical and physical properties make it suitable for maximum reinforcement structures and buildings
• Compatible with skyline structures: Well-suited for strengthening new-age high-rise buildings
• Extremely economical: To make innovational products available for all without compromising on the quality

• HVOST technology soft core (ferrite and pearlite), Extraordinary bonding
• Excellent bonding with cement
• Zero weight and size variation
• Superb welding ability
• Earthquake resistant

• Bond Strength: The bond strength of all SAIL TMT Bars has been tested at the National Test House, Alipore, Kolkata and meets IS 1786-2008 norms. 
• Weldability: These bars are perfectly weldable by normal process of welding with suitable electrodes. They are also weldable without preheating, preferably with low hydrogen ectrode. The weldabillty of bars has been rested and certified by the Welding Research Institute, Trichy.
• Bendability: All bars have lower bend diameter compared to specified bend diameters as per IS 1786-2008, 008, Grade D specification. This allows easier bending with less effort and thus facilities easier onsite works. 
• Earthquake & Fire Resistance: All bars are able to withstand fire hazards when enclosed in concrete up to 600 Degree C, whereas ordinary TMT starts losing its mechanical properties from 250 Degree C. 
• Corrosion Resistance: It is also available in corrosion-resistant variety (NCR) with modified chemical compositions to give enhanced resistance to seismic and corrosive atmospheric conditions.

• Excellent Bond Strength
• Bendability
• Weldability
• Superior Ductility 
• Greater Strength
• Fire & Corrosion Resistant
• Earthquake Resistant 
• Tougher Ductility: Ductility is a property which helps in elongation of TMT Bar and prevents itfrorn snapping abruptly. KVS POWERCON TMT Bars have the rare combination of high strength with ductility. Elongation along with its Yield stress / Proof Stress of a steel rebar plays a major role in its ductility. Elongation of a Steel TMT Bar refers to ability to elongate before failure. It is an ultimate stress/deformation at fracture. Yield stress corresponds to the yield Strength which is maximum load that an element can undertake. UTS or Ultimate Tensile strength defined as ultimate stress a material can withstand, defines the ductility for the material. Studies proven higher tensile strength in TMT Bars result in less consumption of steel. 

• Test For Tensile Strength: The tensile strength , percentage elongation, percentage total elongation at maximum force and 0.2 percent proof stress of bars shall be determined in accordance with requirements of IS: 1608 read in conjunction with IS: 2062.

• Low carbon content and made from fully killed steel.
• Higher yield strength, Ultimate tensile strength and higher percentage elongation when compared to cold twisted bars of same grade.
• Easy bendability, weldability and excellent ductility ensures economy and safety of use.
• In-built ability to resist loss of strength at higher temperature.
• Require less energy for bending and re-bending along with superior reverse bending properties.
• Can be butt welded or lap-welded.
• Use of Fe-500 grade results in saving more than 15% in steel consumption when compared to cold twisted bars.
• Higher corrosion resistance and seismic resistance compared to CTD.
• Ideally suited for any type of concrete structure.

• Combination of high strength and high ductility: VIZAG TMT bars have rare combination of high strength with excellent ductility. The tensile to yield strength ratios are always greater than 1.12. In normal bars, the increase in the yield strength of the bars is accompanied by the loss of percent elongation. But in the case of VIZAG TMT bars this loss is negligible and the percent elongation values are much higher than normally specified in various International Standards. In Fe 500D grade rebars the UTS/YS ratio values are maintained always at more than 1.15.
• Resistance to ageing: The tests carried out on the VIZAG TMT bars, indicate that no significant change of strength as a function of time occurs which could affect the usefulness of these bars.
• Superior corrosion resistance: The absence of Eutectoid Carbides and pearlite colonies in VIZAG TMT, absence of stresses because of tempering, presence of martensitic layer at the outside surface and formation of adherent scale film due to water quenching during rolling are the reasons for better corrosion resistance properties of these reinforcement bars.
• Excellent bendability and workability: The tough outer skin and the ductile core of the VIZAG TMT bars result in excellent bendability. This coupled with a high resistance to low temperature brittle fracture, allows these bars to be bent, without fear of failure around small diameter mandrels. In the reverse bend test, these bars also show good results. In the construction site, situation arises where bars bent are left for a period in the bent condition and then reverse bent. During period between the first bend and the reverse bend the bars may strain age. The loss of ductility due to strain ageing and due to strain imposed from the first bend may cause failure during rebending operations, if the bars are not sufficiently ductile. Test results have shown that VIZAG TMT bars have withstood successfully the bending, straightening and rebending tests after ageing. The bend tests carried out at VSP have shown that these bars could be bent even around smallest dia mandrel without causing any cracking.
