Which outcome increases degradation in concrete support columns when freeze-thaw cycles escalate?

💡 Explanation

Internal cracking worsens because differential expansion creates hydraulic pressure exceeding tensile strength, causing fracture onset. Since it increases cracking, rather than passivation, this allows water penetration; therefore, options involving carbonatation or sulfate attack are less directly related.
