Reinforced Cement Concrete (RCC) Construction

What is Reinforced Concrete?
Reinforced concrete, or RCC, is concrete that contains embedded steel bars, plates, or fibers that strengthen the material. The capability to carry loads by these materials is magnified, and because of this RCC is used extensively in all construction. In fact, it has become the most commonly utilized construction material. Reinforced materials are embedded in the concrete in such a way that the two materials resist the applied forces together. The compressive strength of concrete and the tensile strength of steel form a strong bond to resist these stresses over a long span. Plain concrete is not suitable for most construction projects because it cannot easily withstand the stresses created by vibrations, wind, or other forces.

Performance of Reinforced Concrete
Concrete consists of a cement and stone aggregate mixture that forms a rigid structure with the addition of water. When steel that has a high tensile strength is embedded in concrete, the composite material withstands compression, bending, and tensile stresses. Such a material can be used for making any size and shape, for utilization in the construction.
The main quality of reinforced concrete is similarity of its coefficient of thermal expansion with that of steel, due to which the internal stresses initiated due to variation in thermal expansion or contraction are eliminated. Secondly, on the hardening of the cement paste inside the concrete, it corresponds to the surface features of the steel, allowing the stresses to be efficiently transmitted between the two materials. The cohesive characteristics between the steel and concrete are enhanced by the roughening of steel bars. Thirdly, a film is formed on the steel because of the alkaline environment created by lime, due to which the steel becomes extra-resistant to corrosion.
