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.
Construction of building structures is increasing on a daily basis. With newer technological sophistication introduced, newer strategies are used for making the building stronger during construction. However strong the building may be, it is not matched for natural disasters, especially earthquakes. Earthquakes are one of the biggest challenges for a building structure to overcome because even the strongest buildings do suffer damages from earthquakes.
Building a structure involves planning, resources and time. Every building structures are constructed with the purpose to last long, but when natural disasters like earthquakes, floods, hurricanes strike the buildings, they fall. So normally structures are vulnerable to natural disasters.
