Sustainable utilization of recycled aggregates in repairing concrete: Durability behavior under complicated sulfate-magnesium attack

Key Points

• Durability under sulfate and magnesium attacks is critical for concrete repairs using recycled aggregates.
• The study shows that recycled aggregates can significantly improve resistance to sulfate and magnesium damage.
• Assessment of the material behavior involves rigorous testing methods evaluating mechanical properties and long-term durability.
• Using recycled aggregates in concrete repairs supports sustainability goals but needs further validation under diverse conditions.
