Corrosion Resistance of Concrete - Cement

Corrosion of this rebar caused spalling on a concrete step. The corrosion of reinforcing steel can be a problem in concrete structures. Corrosion of steel produces hydrated iron oxide or rust, which is very expansive. This expansion builds up internal pressure until the concrete fails in the form of spalling. This is a leading cause of concrete
