Consider a reinforcing bar embedded in concrete. In a marine environment this bar undergoes uniform corrosion, which leads to deposition of corrosion products on its surface and an increase in apparent volume of the bar. This subjects the surrounding concrete to expansive pressure. As a result, corrosion cracks appear at surface of concrete. Which of the following statement is true?
A
Corrosion causes circumferential tensile stress in concrete and the cracks will be parallel to corroded reinforcing bar.
B
Corrosion causes radial tensile stresses in concrete and cracks will be parallel to corroded reinforcing bar.
C
Corrosion causes circumferential tensile stresses in concrete and cracks will be perpendicular to the direction corroded reinforcing bar.
D
Corrosion causes radial tensile stresses in concrete and cracks will be perpendicular to direction of the corroded reinforcing bar.
