Impacts of recycled aggregates on the degradation of in-situ repaired concrete induced by sulfate-magnesium and dry-wet combined attack

Key Points

• Recycled aggregates may improve resistance against degradation caused by sulfate-magnesium attacks and dry-wet cycles.
• The analysis revealed significant degradation differences between traditional and recycled aggregates in concrete.
• Assessment of the impact involved both sulfate exposure and dry-wet cycles over a defined period.
• Findings suggest the potential for enhancing concrete durability using recycled aggregates in future construction.
