Abstract
En 中文
• Elucidated the thermochemical coupling mechanisms governing PET–GGBFS synergy. • Temperature-dependent ITZ evolution defined a sustainable recycled PET incorporation window. • Porosity growth quantitatively explained thermal strength loss in recycled PET–GGBFS composites. • 10 vol% PET achieved the best balance between waste utilization and thermal performance.
