Which risk increases when epoxy-coated rebar is bent after significant corrosion develops?

💡 Explanation

When corroded epoxy-coated rebar is bent, coating delamination occurs because corrosion products increase stress at bend points allowing moisture between steel and coat reducing adhesion thereby decreasing bond. Therefore loss of bond strength occurs, rather than embrittlement , galvanic action or spalling, which entail separate mechanisms with different conditions.
