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.
Use of Thermo Mechanically Treated (TMT) reinforced bars for construction is now a standard practice. With newer technologies developing, it results in efficient constructions strategies which in turn improves the lifespan and structural integrity of the building structure. However strong the building structure claims to be, in order to for its longevity the building structure has to face several hurdles, even the natural disasters.
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.
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.
Steel is the most widely used material in the construction field. Being an alloy of Iron, Carbon, it is known for its high tensile strength and low cost. Before the inclusion of steel, concrete was solely used for building structures but the catch was that concrete could only deal with the compressive strength of the structure and couldn’t deal with the tensile strength. This situation was quite a challenge to overcome until the introduction of reinforcement.
Iron is one of the most used versatile metal in the world. Normally Iron is found in ores. Iron ores are rocks from which iron is extracted for the purpose of processing iron which in turn is further reformed to produce reinforced steel bars. Iron ores are not pure, they contain elements like Sulfur, Phosphorus, Carbon etc. These elements are present in high percentage which results in brittleness and less tensile strength for the metal.
Thermo Mechanically Treated (TMT) process has been developed for providing quality reinforcement to structures. The TMT process is a revolutionary process as it provides the steel bars high tensile strength as well as ductility. There are different grades for TMT reinforced steels namely Fe 415, Fe 500, Fe 550, Fe 600, where the numbers denote the minimum yield strength.
