Consider a reinforcing bar embedded in concrete. In a marine environment this bar undergoes uniform corrosion, which leads to the deposition of corrosion products on its surface and an increase in the apparent volume of the bar. This subjects the surrounding concrete to expansive pressure. As a result, corrosion induced cracks appear at the surface of concrete. Which of the following statements is TRUE?

Question

Examsnet · Accepted Answer

Correct Answer is : Corrosion causes radial tensile stresses in concrete and the cracks will be parallel to the corroded reinforcing bar.
