The reinforcing steel, which may go ahead and take kind of rods, bars, or mesh, contributes tensile strength. Basic concrete will not conveniently withstand stresses such as wind motion, earthquakes, and vibrations together with other bending forces and it is therefore unsuitable in several structural applications.
