Concrete is the most vital material in the construction of buildings. There is no need for any sort of familiarization for us. It is right around us, buildings, roads, bridges, etc, all these structures are made with concrete. It is impossible to imagine a structure without concrete. The use of concrete has a long way back since ancient times. The arrival of concrete drastically changed the course of architecture in the world.
Building collapsing, explosions, all seems good and spectacular in movies, right? but not so in real life. Part-I of this blog explained about the dangers and consequences involved in collapsing of the building. The blog also described the reasons for various building collapse which were lack of maintenance and inefficient planning and design. Here we solely focus on the inefficiency and practices of the people involved in the construction process with a recent example.
Buildings collapsing is not something enjoyable to view and experience. The impacts created from these disasters create great physical and mental trauma that takes a big toll on our life. It gives us a lot to think about and improve but still, the event continues in different areas all over India. There are many instances where different cases on building collapses have been reported. The sad thing is that the responsible officials never learn or do anything effective even after repeated patterns of the same event.
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 reinforced steels are currently the defacto standard for constructing commercial building projects and residential buildings. Known for its high tensile strength and ductility ratio, it is the ultimate option for reinforcement. Part I of this blog explained about TMT steel and its manufacturing process. To get the complete effect of the reinforced bar, there are certain things that must not be done. Some of these steps were explained in Part-I. Here we further a few more features.
TMT reinforced steel is the ultimate solution for reinforcement of a commercial structure. What the steels provide are the necessary tensile strength and ductility that is needed for the structure to withstand the forces of nature effectively and increased longevity to structure. The TMT steels are used because of its high tensile strength and ductility, which is resulted from the QST process that the reinforced bar undergo.
Our last blog described the TMT steel bars and its importance as reinforcement for the construction of commercial buildings. More specifically, it described the standard IS 1786:2008 that every reinforced steel bar should conform to. The IS standard defines certain guidelines that must be followed when manufacturing the reinforced steel bar.
Reinforced steel is the most important component in the construction of buildings. Its multiple advantages in terms of strength and ductility are the sole reason for its increasing popularity and demand. Different versions of reinforced steel bars were introduced such as Mild Steel, HYSD etc. Each had their particular advantages that made it better than its predecessors. However, with the demand for more strength led to introducing stronger and better-reinforced steel bars. One such example is the TMT steel bars.
