Its creation is usually attributed to Joseph Monier, a Parisian gardener who manufactured yard pots and tubs of concrete reinforced with iron mesh; he received a patent in 1867. The reinforcing steel, which may take the kind of rods, bars, or mesh, contributes tensile energy. Simple concrete doesn't very easily withstand stresses for instance wind motion, earthquakes, and vibrations and other bending forces and is also consequently unsuitable in many structural programs.
