Abstract

This study investigates the chemical and physical properties of fine and coarse aggregates and their implications for concrete performance. The research employed an experimental approach to analyze various parameters, including chemical composition, chloride content, particle distribution, and slump, among others. The mixed proportions of concrete were carefully controlled to assess the influence of different aggregate compositions on concrete properties. The study utilized ASTM standards for testing procedures and calculations. Key findings of the research include the significant impact of chemical composition on concrete properties, with variations in oxides such as MgO, Al2O3, SiO2, K2O, CaO, Fe2O3 and Na2O influencing setting time and strength development. Moreover, the chloride content of fine aggregates varied across different sources, with implications for concrete durability. Particle distribution analysis revealed the importance of optimizing aggregate gradation for desired concrete properties. The study’s outcomes emphasize the importance of careful mix design and aggregate selection in optimizing concrete performance and durability. Recommendations for future research include further exploration of the mechanical behavior properties of concrete and assessment of environmental sustainability considerations in aggregate production processes. This research contributes valuable insights into optimizing concrete mix designs and enhancing the durability of concrete structures. Based on the findings, it is recommended to carefully consider aggregate characteristics and sources to achieve desired concrete properties. Overall, this study underscores the significance of aggregate selection in achieving durable and sustainable concrete structures.
