This research investigates the influential role of aggregate gradation in optimizing concrete compressive strength while preserving workability with different combination of gradations ranging 60-40, 55-45, 50-50, 45-55, 40-60 for aggregates. The selection of aggregate gradation profoundly impacts concrete performance, making it a critical consideration for engineers and producers in meeting project-specific requirements.The study encompasses comprehensive experimentation with various aggregate gradations in concrete mixes, focusing on testing their compressive strengths and analyzing outcomes. The primary objectives include determining the most optimized aggregate gradation for maximizing compressive strength, comparing different aggregate gradations' impact on concrete strength, and assessing their interplay with workability. The experimental investigation involves two parts. Initially, material properties of cement, course aggregates, fine aggregates, slag sand, and M sand are analyzed for their physical and mechanical characteristics. Subsequently, utilizing the M-25 grade as per IS10262-2019 standards, mix designs are implemented.
