Which risk increases significantly when reinforced concrete beam experiences sulfate attack?

💡 Explanation

When a reinforced concrete beam experiences sulfate attack, a chemical reaction forms expansive products like ettringite, creating internal pressure that cracks the concrete and exposes the rebar. Therefore, rebar corrosion risk significantly increases due to this expansive force, rather than shear failure, buckling, or creep which involve other distinct mechanisms.
