    OverviewDescriptionHistoryUse in constructionBehavior of reinforced concreteReinforcement and terminology of beamsPrestressed concreteCommon failure modes of steel reinforced concrete

    Reinforced concrete (RC) (also called reinforced cement concrete or RCC) is a composite material in which concrete's 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 (rebar) and is usually embedded passively in the concrete before the concrete sets.
