Rebar Corrosion In Concrete – Does Rebar Rust?

While steel reinforcement solves one of concrete’s greatest limitations, it creates an entirely new problem: Corrosion of embedded steel rebar is the most common form of concrete deterioration.//Practical Engineering

There are lots of ways to combat this problem, a few of which we discuss/demonstrate in this video, including fiber reinforced concrete, adequate protective cover, and fiber reinforced polymer bars.Watch the video from  Practical Engineering for more info:

The main cause of concrete deterioration. As chlorides diffuse into the concrete some are trapped in a ‘bound’ form while the rest, ‘free’ chlorides, diffuse further and cause corrosion as they reach the carbon steel rebar.

Corrosion of reinforcing steel and other embedded metals is the leading cause of deterioration inconcrete.When steel corrodes, the resulting rust occupies a greater volume than the steel. This expansion creates tensile stresses in the concrete, which can eventually cause cracking, delamination, and spalling./ivia:cement
