Within a high-rise concrete support column, which risk increases when rapid hydration occurs?

💡 Explanation

Excessive heat induces ettringite formation through internal sulfate attack; this expansion weakens the binder through delayed 'Delayed Ettringite Formation' (DEF). Therefore, the compressive strength decreases, rather than the alternatives involving shear stress; DEF impacts compressive, but not shear, strength.
