There are some tests to ensure the quality of the TMT bar. The following tests determine the strength and elongation.

TENSILE TESTING:

The manufactured Rebars tested for consistency with the help of a Universal Testing Machine (UTM). The strength of rebars is measured using a UTM only when the diameter of the Rebar is above 32mm according to IS 1786, for Rebars with 32mm capacity can be tested without the need for a UTM to measure the strength of reinforcement bars. 

YIELD STRESS TESTING:

How do you determine up to which level the material can handle stress? And when it starts to deform plastically? Knowing the Yield Stress can give you answers to your questions. Until the material reached the Yield Point, it will continue to elastically Deform and get back to its original shape only when stress is released.

Therefore, the materials are divided based on the behaviour into two types, ductile and brittle. Steel and Aluminium are Ductile materials, while Glass and cast iron are brittle materials. The two categories are distinguished by comparing the stress-strain diagram.

BEND/RE-BEND TESTING:

Choosing the wrong material for the manufacture of Rebars can lead to poor quality that bends easily. It is crucial to evaluate the Rebar either during a purchase or in the construction site to check its bending properties. This test ensures that the bending radii are not below the relative standard sizes. The performance of steel reinforcement can be badly affected due to incorrect bending. 

CHEMICAL ANALYSIS:

The chemical test performed by inspecting the chemical composition testing in the spectrometer takes a few seconds to give results in a printed form of the 26 elements present in the TMT bar. Chemical Analysis is used to find the percentages of Carbon, Phosphorus, Copper, Manganese, Chromium, and Sulphur with the spectrometer. Detailed quantitative and qualitative analyses performed using this advanced instrument.

So, when you decide to buy TMT bars for the construction of your home, to make sure your home lasts long, choose the best TMT bar.

HOW DO TMT BARS SAFEGUARD CONSTRUCTIONS AGAINST NATURAL DISASTERS?

Fire: There are many natural disasters, but fire is the most damaging and can cause the worst damage. They mainly disturb the structure and stability of the building structure. The fire safety of the structure is one of the most important concerns for engineers and builders. TMT rods have a high thermal capacity and are known to withstand temperatures ranging from 450 degrees to 600 degrees Celsius. High fire resistance makes TMT Bars perfect for fighting the fire and providing safety.

Rain: Floods can cause damage to construction due to shear wear & tear as well as corrosion caused due to prolonged exposure to water. TMT Bars offer protection in humid environments such as coastal areas and marine constructions. The methods employed in the manufacturing of TMT Bars offer them high corrosion resistance and thus make them ideal for the home construction as they do not need further cold twisting to make them corrosion resistant.

Earthquakes: TMT bars are resistant to earthquakes, thanks to their pearlite core, this gives it high ductility with high fatigue confrontation to tolerate dynamic loading and helps buildings absorb the vibration caused by the earthquake to a large extent and minimizes damages caused. Earthquakes cause a huge loss of property and destruction, so TMT rods are widely used in the construction of structures in earthquake-prone areas.

Storms: TMT bars are known for their high strength and the stability they provide to structures. Strong winds can cause damages to buildings and pose an imminent threat throughout all phases of the construction. Hurricanes and storms create strong winds that damage property and TMT Bars offer a better chance at building stronger structures that can withstand the damage.
