This report presents the results of an experimental study conducted to evaluate the properties and performance of concrete mixtures for use in construction. The study focused on assessing the impact of various factors, including the type of aggregates, The impact of the water-to-cement ratio and chemical admixtures on workability compressive strength, and durability of concrete. A series of laboratory tests were performed, including slump tests for workability, compressive strength tests at 7, 28, and 56 days, and durability tests to assess resistance to freeze-thaw cycles and sulphate attack. The findings of this study provide valuable insights into optimizing concrete formulations for improved structural performance and long-term sustainability. The results indicate that the incorporation of certain admixtures and careful control of the water-cement ratio can significantly enhance the strength and durability of concrete, making it more suitable for demanding construction environments. The report concludes with recommendations for best practices in concrete mix design and the implications for future research in material optimization.
