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.
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.
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.
The last blog described the universal problem affecting the RCC which is corrosion / rusting and what are the causes of corrosion. In order for a Reinforced structure to have corrosion, the presence of these two components is needed which is moisture and air. Usually, corrosion starts out slowly and results in severe damages which in turn affects the structural integrity of the building.
Thermo Mechanically treated steel bars created the current standard of reinforcement. Their excellent tensile strength and ductility make them ideal and preferred for construction of building structures. Building structures are always susceptible to environmental changes. No building will ever be the same once the environmental changes kick in. Out of all the changes, the most serious and devastating is corrosion.
