Sažetak

This study investigates the accelerated carbonation hardening (ACH) of lightweight aggregate concrete. It evaluates the effects of binder content, ground limestone, lightweight aggregates, plasticizers, carbonation pressure, and duration on compressive strength at 1 hour, 28 days, and 180 days. Statistical models and optimization using desirability functions were employed to identify optimal recipe and technological parameters. ACH enhances concrete strength and promotes sustainable carbon sequestration, providing an alternative to conventional curing methods.
