Abstract:

This study investigates the impact of aggregate size on key concrete properties, including compressive strength, permeability, and deformation behavior. By examining a range of aggregate gradations, the research evaluates how varying particle sizes influence the overall performance of concrete. Experimental analysis reveals that aggregate size plays a crucial role in determining compressive strength, with finer aggregates generally enhancing strength but reducing permeability. Conversely, larger aggregates tend to increase permeability while decreasing resistance to deformation. The study also identifies an optimal balance in aggregate grading that improves both strength and durability. These findings offer valuable insights for optimizing concrete mix design, enabling tailored applications in structural and infrastructural construction projects. The results contribute to a better understanding of material behavior, aiding engineers and designers in selecting appropriate aggregate sizes to meet specific performance criteria. This research underscores the importance of aggregate gradation in achieving the desired concrete performance.
