Corrosion Resistance of Concrete - Portland Cement

The most common cause of steel corrosion is chloride ingress (see Corrosion of Embedded Metals). Any reinforced concrete exposed to moisture and external chlorides, be it from seawater or deicer salts, is considered to be in a severe corrosion environment. This condition requires a minimum design strength of 5,000 psi and a maximum w/cm of 0.40.

Reinforced concrete - Wikipedia

Reinforced concrete (RC), also called reinforced cement concrete (RCC), 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 bars and is usually embedded passively in the concrete before the concrete ...
