The construction industry faces dual demands for decarbonization and longevity. However, existing research often addresses decarbonization and durability separately. Achieving synergistic carbon reduction and service life extension through advanced materials and paradigm shift remains a critical challenge. The speaker has developed a multi-scale design framework — a novel corrosion-based service life model in concrete level, a load-harsh environment coupled durability model in reinforcement level and a whole life carbon-durable design framework in structure level. These advances unveil the mechanisms between decarbonization and durability enhancement in reinforced concrete structures, effectively lowering carbon footprint of buildings while extending service life. Such achievements can provide critical theoretical and technical supports for national carbon neutral initiative.
