  • Reinforced concrete Wikipedia

    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 and is usually embedded passively in the concrete before the

  • Failure Modes in Concrete Beams: Flexural and Shear Failure

    The flexural compression failure begins by crushing of concrete at compression side followed by yielding of steel at tension side of the beam. It occurs when the beam is over-reinforced which means the beam reinforcement ratio is greater than balanced reinforcement ratio as per ACI 318-14.

    When structures made of concrete are demolished or renovated, concrete recycling is an increasingly common method of utilizing the rubble. Concrete was once routinely trucked to landfills for disposal, but recycling has a number of benefits that have made it a more attractive option in this age of greater environmental awareness, more environmental laws, and the desire to keep construction costs down. Concrete aggregate collected from demolition sites is put through a crushing machine. Crushing facilities a

    Concrete members reinforced with steel rebars are designed to behave in a tension-controlled manner, in which the yielding of steel precedes the crushing of concrete. Yielding of the steel rebars leads to wide cracks and large deformation which gives a warning of pending failure of structural members.
