reinforced concrete
Also known as RC, ferroconcrete, reinforced cement concrete, RCC
composite building material
AI overview
Reinforced concrete is a composite building material made by combining concrete with steel reinforcement, which together create a stronger structure than either material alone. It matters because this combination allows concrete to withstand both compression and tension forces, making it ideal for constructing buildings, bridges, and other infrastructure that must bear heavy loads.

Article
Reinforced concrete, also called ferroconcrete or ferro-concrete, is a composite material in which concrete's relatively low tensile strength and ductility are compensated for by the inclusion of reinforcement having higher tensile strength or ductility. The reinforcement is usually, though not necessarily, steel reinforcing bars (known as rebar) and is usually embedded passively in the concrete before the concrete sets. However, post-tensioning is also employed as a technique to reinforce the concrete. In terms of volume used annually, it is one of the most common engineering materials. In corrosion engineering terms, when designed correctly, the alkalinity of the concrete protects the steel rebar from corrosion.
