Thermal-fatigue challenges in the interfacial transition zone (ITZ) of concrete: How fly ash modulates degradation?

Key Points

• Fly ash modulates thermal-fatigue degradation in the interfacial transition zone of concrete, enhancing performance.
• Significant improvements in durability metrics were achieved with different fly ash blends in concrete mixtures.
• Analysis through experimental testing on concrete samples subjected to thermal cycling reveals new insights.
• Understanding these interactions may enable better material design, highlighting a sustainable approach in construction.
