(Yes, you heard right, those two idiotic friends of mine who met you before signifying importance of cement are now interested to guide you even further. For a recall, Piu’s house was getting to be renovated and was still in under-construction, while Chiru is a resourceful girl. So now, let’s see what his house is upto.)
Chiru : Hey it’s really been a long time, How’s your house renovation going?
Piu : Well, that’s going good and I have something very interesting similarity between me and my new house!
Chiru : Similarity? But what?
Piu : I knew I’ll get a puzzled face after you know that my new house too got spikes on its head like me! Those steel bars won my heart in perfectly arranging themselves like my hairstyle.
Chiru : That’s pretty weird!!! Well, concerning about steel bars, they are famous by their name Reinforcement as a use in tension device in reinforced concrete and respective structure built is Reinforced Cement Concrete (RCC) structure.
Piu : Oh, now I’m more curious to know who first brought these spikes into existence?
Chiru : Then you should thank François Coignet for using it as iron-reinforced concrete in building structures. Moreover, he did it for creating a monolithic construction preventing from overturning rather than imparting strength to the building! The theory of increased tensile strength was found later.
Piu : Wow, inventing something without knowing is really surprising.
Chiru : Yes it is. A pioneer in the development of structural, prefabricated and reinforced concrete Joseph Monier was once dissatisfied with existing materials available for making durable flowerpots. Eventually he was granted a patent for reinforced flowerpots by means of mixing a wire mesh to a mortar shell and received another patent for advanced techniques in column grid pattern.
Among the two people, Ernest L. Ransome used Monier’s knowledge and innovated nearly all styles and techniques of the previous known inventors of reinforced concrete such as, twisting the reinforcing steel bar improving bonding with the concrete. The second person was G. A. Wayss, who purchased the German rights to Monier’s licenses and in 1884, he began the first business use for fortified cement in quite a while firm Wayss and Freytag.
Piu : That means use of reinforced concrete was from around 150 years ago!
Chiru : Being specific, In 1904 Julia Morgan, an American designer and architect who spearheaded the stylish utilization of fortified concrete, finished her previously strengthened solid structure, the 72-foot chime tower at Mills College, El Campanil, which is situated over the cove from San Francisco. After two years, El Campanil endure the 1906 San Francisco seismic tremor with no harm, which helped assemble her notoriety and dispatch her productive vocation.
And eventually, many discoveries and inventions took places with appropriate design rules coded countrywide.
Piu : Remarkable one! But are there only steel reinforcements used till date?
Chiru : No, not only but majorly. The rest find their advantage in nonmetallic reinforcements which are called Fibre Reinforcements or FRC. They are mostly used for on-ground floors and pavements, but can also be considered for a wide range of construction parts (beams, pillars, foundations, etc.), either alone or with hand-tied rebars.
Piu : Well my spikes are so well innovated was totally unknown for me. I must say thanks for great information.
