Engineers build leaving a wide berth of safe loading capacity to construct, let’s get a brief view on how the same is for steel reinforcement bars. We have talked enormously on safety codes listed in IS 1786:2008, in the manufacture of reinforcement bars. Now, let’s discuss how safe loads are calculated in a construction material like reinforcement bars. The min. yield strength a reinforcement bar should have is easily inferred from the grade of the reinforcement purchased. Grade Fe 415 having a min. yield strength of 415 N/mm2, similarly for grade Fe 500 having min. yield strength of 500 N/mm2 and Fe 550 with min. yield strength of 550 N/mm2, so goes for every steel reinforcement grade.
The construction of a commercial or residential building cannot be imagined without the use of concrete and steel. These two components are the most essential composite in the construction field. The reasons why they are preferred is their advantages in terms of strength and withstanding the loads. However, what if a comparison was made between concrete and steel. To see which one tops the other in terms of certain parameters.
So, which material surpasses the other in the field of construction – concrete or steel?. We know that both are important for constructing a structure but let us find out what these two materials are capable of.
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.
House is every common man’s dream. It is not just a shelter, but a place filled with fond memories. So every home must be durable and strong to withstand adverse conditions and protect the loved ones. Concrete is the most widely used material for constructing. It provides high compressive strength, but low tensile strength. Due to this factor, concrete would fail from tensile stresses. All concrete structures will crack to some extent, due to shrinkage and tension, therefore it needs reinforcement.
