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.
Part-I and Part-II broadly explained the two alternatives for steel reinforcement. One was Basalt rebars and the other one was Bamboo reinforcement. Each of this reinforcement techniques has their own advantages and features that are equal to or more than steel. But, however, when we look at the construction sector, one thing we can find is that steel reinforcement is still preferred for the construction of building structures.
Our last blog described on steel reinforcements and its multiple benefits to the construction sector, also, the concept of alternatives was explained. Even one such alternative namely the Basalt reinforcement was briefly explained along with its advantages. When compared to steel, basalt reinforcement bars or rebars had more tensile strength and was much lighter than steel. Well, another alternative reinforcement technique is Bamboo reinforcement.
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.
Reinforced cement concrete, simply RCC is the preferred standard for constructing building structures. The concept of RCC was introduced by Joseph Monier in the late 19th century. Reinforced cement concrete is primarily used in structures to provide the tensile strength that the concrete is weak to handle. Due to the excellent tensile strength handling and similar thermal coefficient of expansion between steel and concrete, RCC remains as the de facto component in the construction of a building.
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.
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.
