Key Points
GGBS enhances late-age strength and improves transport properties in concrete, indicating long-term performance advantages.
Crumb rubber reduces density and static modulus while enhancing impact resistance and freeze-thaw resilience in structural mixes.
Optimal concrete performance is achieved with 40% GGBS and 5–10% crumb rubber for acceptable strength and durability.
Statistical analysis quantifies main and interaction effects of GGBS and crumb rubber on concrete properties using ANOVA.
