Reinforced concrete Wikipedia
Reinforced concrete RC also called reinforced cement concrete or RCC is a posite material in which concretes relatively low tensile strength and ductility are counteracted by the inclusion of reinforcement having higher tensile strength or ductility The reinforcement is usually, though not necessarily, steel reinforcing bars and is usually embedded passively in the concrete before the
