WHY CONCRETE NEED REINFORCEMENT ??

Reinforced concrete is mostly used for construction on a large scale due to its desirable mechanical properties. Reinforced concrete, or RCC, is concrete that contains embedded steel bars, plates, or fibers that strengthen the material.

Why concrete is reinforced??

Concrete can be very strong when it comes to absorbing stress in the form of compression. However, it does not perform well against tensile strength and crumbles when up against forces that tries to pull it apart. Concrete always experiences both kinds of stress in construction and if weight is put on the concrete beam from the top, it will hold up but deforms when it experiences tensile stress.

Reinforced materials are embedded in the concrete in such a way that the two materials resist the applied forces together.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.
