Over the past few months, a slew of fire accidents has occurred In India damaging human lives, properties and goods. In a tragic incident, 20 students died after a fire broke out in a private coaching center in Surat, Gujarat last month. Eyewitness recall that in a bid to escape the blaze, students were seen jumping and falling from the third and fourth floors of the building. This accident is just one of the countless fire tragedies in the country.
Reinforced steel is the most important component in the construction of buildings. Its multiple advantages in terms of strength and ductility are the sole reason for its increasing popularity and demand. Different versions of reinforced steel bars were introduced such as Mild Steel, HYSD etc. Each had their particular advantages that made it better than its predecessors. However, with the demand for more strength led to introducing stronger and better-reinforced steel bars. One such example is the TMT steel bars.
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.
Reinforced steel bars have played a major role in the rise of the construction sector by evolving with the demands of the construction sector to provide safer buildings. The use of steel bars as reinforcement started from the 19th century. The rising demands led to the innovation of technologies that refined steel reinforced bars, used for constructing structures.
Reinforced steel bars are the commonly used materials today in the field of construction whether it is for constructing homes, buildings or any structure. Initially, I was preferred for reinforcement of structures but when stronger iterations were introduced, the people made a wrong choice by favoring them. My name is Fe 415.
The previous blog described the alternative environment-friendly route to the conventional blast furnace known as the Corex process. It is a type of smelting reduction process which produces it by using non-coking coal instead of metallurgical coke, which is used by the Blast Furnace. The corex process consists of two parts namely Reduction stage and Melter-gasifier.
A building structure is incomplete without the right set of resources. There are many different resources involved in the construction of a building but the most important resource is the reinforced steel bar. The types of reinforced steel bar grades are Fe 415, Fe 500, Fe 550, Fe 600. The manufacture of steel begins with the steel making process, in which pig iron is purified and alloyed to make ingots.
Well, the last blog was all about the prevention of corrosion on reinforcement steel bars and two methods used for the prevention were described, but only one method was fully detailed. The other method is detailed right here. Let’s buckle up.
Corrosion is not something to be taken lightly. It poses a dangerous threat to the overall strength of the building structure. Corrosion starts out pretty much simple and advances through several stages that result in the eventual collapsing of the structure. Even though corrosion is threatening for RCC, there are preventive measures that can be taken to considerably delay the corrosion effects.
Construction of a house requires perfect planning and the sufficient strength to withstand loads of the structure and the certain natural disasters. In order to deliver such strength, the TMT steel reinforced bars are primarily used. Thermo Mechanically Treated (TMT) steel reinforced bars are known for their absolute strength and ductility. TMT is actually an innovated procedure performed on the hot rolled steel bars, which results in a strong outer martensite layer that deals the tensile strength and a soft ferrite-pearlite inner core which deals with the ductility factor. TMT reinforced steel bars are known for its Bendability.
