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.
The construction of a building is virtually incomplete without reinforcement. In construction, Steel is the primary alloy used for reinforcement. There is a reason for that because as we know that concrete is used for the construction of the building, even though it provides the compressive strength, it has weak tensile strength for withstanding induced forces. Therefore by combining reinforced bars, it provides the tensile strength for concrete to withstand induced forces. Also, The properties of thermal expansion for both steel and concrete are approximately the same which is why steel is used as reinforcement.
Part-I of this blog explained the current reinforcement steel trend in India, the TMT steel reinforced bar, the different grades and which grades are preferred. It also explained the most important factor of TMT steel bar which is Ductility. How is it compromised for higher strength. In this blog, the shift towards value-added reinforced steel is explained
Reinforced steel bars or rebars has become the preferred standard for construction of building structures, bridges and many other commercial structures. The most popular among them is the Thermo Mechanically Treated ( TMT) reinforced bars. About 35% of the total steel production in the country was accounted by the reinforced steel industry. Usage of high strength TMT steel rebars has ensured rapid growth within the construction sector.
Steel, an alloy of Iron, carbon and other materials, is the most widely used component used in the field of construction of buildings, automobiles, weapons and much more. Steel is manufactured from the steelmaking process. Steelmaking process has a long history since ancient times, although this procedure was commercialized in the late 19th century.
Steelmaking is one of the most important processes in the industrial sector all over the world. Steelmaking results in the production of steel from iron ores, which is used for a variety of purposes ranging from construction of roads, railways, infrastructures, automobiles and buildings. Even the most innovated TMT reinforced steel bars like the Fe 415, Fe 500 etc are developed from the steelmaking process. The demands for steel are always increasing to the point that we cannot imagine a world without steel.
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.
