Synergistic Effects of EAF Slag Aggregate, Silica Fume, and Fibers on Mechanical and Microstructural Performance of Sustainable Concrete
This study evaluates concrete in which natural aggregates (NAs) are replaced by electric arc furnace (EAF) slag siderurgical aggregate (SA), with partial cement replacement by silica fume and reinforcement using steel and polypropylene fibers. Mechanical tests (compressive and flexural) at 7, 28, and 90 days and mi...
