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.
Steel is the most widely used material in the construction field. Being an alloy of Iron, Carbon, it is known for its high tensile strength and low cost. Before the inclusion of steel, concrete was solely used for building structures but the catch was that concrete could only deal with the compressive strength of the structure and couldn’t deal with the tensile strength. This situation was quite a challenge to overcome until the introduction of reinforcement.
My previous blog explained the stages of manufacturing TMT steel bar grade Fe 415 and special TMT grades bars. Did you know that Fe 415 is called a true grade TMT steel bar?
Have you wondered why Fe 415 is the true TMT grade?
It’s the original TMT bar that provides an optimum high tensile strength and ductility and by changing its manufacturing process slightly, produces different variations with higher strengths but less ductility TMT bars called the special TMT bars such as Fe 500, Fe 550, Fe 600.
