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 (rebar

Properties of concrete - Wikipedia

Concrete can also be prestressed (reducing tensile stress) using internal steel cables (tendons), allowing for beams or slabs with a longer span than is practical with reinforced concrete alone. Inspection of existing concrete structures can be non-destructive if carried out with equipment such as a Schmidt hammer , which is sometimes used to estimate relative concrete strengths in the field.
