For the past 100 years, reinforced steel bars have been dominating and still dominates the construction industry. The prime reason for that can be attributed to the properties of steel itself which is it’s high tensile strength and ductility ratio. Along with that steel has an almost similar thermal coefficient of expansion to that of concrete. There are many other advantages such as recycling that makes steel the preferred choice for reinforcement of building structures.
Reinforced cement concrete, simply RCC is the preferred standard for constructing building structures. The concept of RCC was introduced by Joseph Monier in the late 19th century. Reinforced cement concrete is primarily used in structures to provide the tensile strength that the concrete is weak to handle. Due to the excellent tensile strength handling and similar thermal coefficient of expansion between steel and concrete, RCC remains as the de facto component in the construction of a building.
The introduction of reinforcement drastically changed the phase of construction of building structures of steel. Reinforced steel provided the necessary tensile strength which the concrete lacks. Today, very few constructions are done without using reinforced cement concrete. At the current scenario, the most used reinforced steel bars are the Thermomechanically Treated (TMT) steel reinforced bars. They are preferred for their excellent tensile strength and optimum ductility. The TMT steel bars are of different grades namely Fe 415, Fe 500, Fe 550 and Fe 600.
TMT steel reinforced bars have been used in constructions of building structures for a long time. They are primarily preferred due to the advantages offered in terms of tensile strength and ductility ratio. TMT Steel reinforced bars consists of different grades namely Fe 415, Fe 500, Fe 550 and Fe 600. Because of the availability of different grades and many dealers promoting different versions of the steel reinforced bars, purchasing the right TMT steel reinforced bar is an important task
When it comes to constructing a building structure, the right set of resources must be used for ensuring the overall life and the integrity of the building. The introduction of reinforcement in construction improved the overall life expectancy of the structure and made them strong enough to withstand the forces of nature. Steel is the primary component used as reinforcement because of its excellent tensile strength, recyclability and similar thermal coefficient of expansion to that of concrete.
Natural disasters are usually one of the troublesome challenges for building structures to overcome particularly, the reinforced steel. Natural disasters are of many types, but the most common disaster occurrence in our country are earthquakes. There are many scenarios of structural collapses due to earthquakes. Although the causes can be attributed to several factors such as the age of building structure, lack of maintenance etc, the most important factor to be attributed is the ductile nature.
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.
In reinforcement of steel bars, splicing technique is generally used to produce a single large reinforced steel bar by joining two similar length reinforced bars and wiring them.
The current construction of building structures is dominated by reinforced steel. Reinforced steel bars are preferred for their unmatched tensile strength which the concrete is weak to provide and ductility factor, that helps to withstand the load of the structure. There are different grades and different diameters (mm) of the reinforced bars in the current market namely Fe 415, Fe 500, Fe 550 and Fe 600.
