The principal components in every construction of a building are concrete and reinforced steel. However, concrete is the pivotal component the construction begins with. Concrete is a composite of multiple items namely cement, water, sand and aggregates. The aggregates include limestone, gravel, crushed stone, slug etc. About 60 to 80% of the concrete mix is made of aggregates. They provide the required compressive strength and bulk to concrete.
Concrete and steel are the two most vital components for the construction of a building. Concrete is known for its impressive compressive strength but it lacks the tensile strength. This tensile strength is provided by using reinforced steel bars. So both these components are needed for the construction. However, with the rise of technologies, different variants of steel, concrete etc have been introduced. One such material is Prestressed Concrete.

TMT steel reinforced bars have been used in constructions of building structures for a long time. They are primarily preferred due to the advantages offered in terms of tensile strength and ductility ratio. TMT Steel reinforced bars consists of different grades namely Fe 415, Fe 500, Fe 550 and Fe 600. Because of the availability of different grades and many dealers promoting different versions of the steel reinforced bars, purchasing the right TMT steel reinforced bar is an important task
Natural disasters are usually one of the troublesome challenges for building structures to overcome particularly, the reinforced steel. Natural disasters are of many types, but the most common disaster occurrence in our country are earthquakes. There are many scenarios of structural collapses due to earthquakes. Although the causes can be attributed to several factors such as the age of building structure, lack of maintenance etc, the most important factor to be attributed is the ductile nature.
In reinforcement of steel bars, splicing technique is generally used to produce a single large reinforced steel bar by joining two similar length reinforced bars and wiring them.
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.
