Abstract	Abstract: This study investigates the durability performance of M30 grade Normal Conventional Concrete (NCC) and Self-Compacting Concrete (SCC) incorporating a quaternary blend of Supplementary Cementitious Materials (SCMs)—Fly Ash, Ground Granulated Blast Furnace Slag (GGBS), and Silica Fume—along with varying volumes of steel fibers (0.5%, 1.0%, 1.5%). Durability properties assessed include acid resistance, sulfate resistance, water absorption, and rapid chloride penetration. The results demonstrate that SCC outperforms NCC in terms of reduced permeability and better resistance to aggressive environments, particularly at higher steel fiber content. SEM and EDS analyses confirm a denser microstructure and stronger hydration products in SCC. The optimal performance was achieved with 1.5% steel fiber dosage combined with the quaternary blend.
