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 ...

Concrete recycling - Wikipedia

Concrete aggregate collected from demolition sites is put through a crushing machine. Crushing facilities accept only uncontaminated concrete, which must be free of trash, wood, paper and other such materials. Metals such as rebar are accepted, since they can be removed with magnets and other sorting devices and melted down for recycling elsewhere.

Concrete Crushing - an overview | ScienceDirect Topics

The desired concrete crushing failures shown in Figs. 1.24 and 1.25 can only be achieved if IC, CDC and PE debonding can be prevented from occurring before the design load to cause concrete crushing. However, this may not always be possible; in which case, it may be necessary to design for either IC or CDC debonding to occur at the design load so that concrete crushing will not occur.

Three Stages in the Life of a Reinforced Concrete Beam

Three Stages in the Life of a Reinforced Concrete Beam Reinforced concrete, considered "low‐tech" by some, is actually complex. It consists of two materials, steel and concrete; the concrete can be cracked or uncracked; and the load‐deformation behavior of both the steel and the concrete are non‐linear at failure.
