Over the decades, research works concentrate on the sustainable development of materials towards to attain the good strength and construction material with durability properties. Too, making sustainable concrete is one of the challenging tasks to maintain its regular properties without affecting the environment. This research work concentrates on the study of the concrete mechanical properties by adding the silica fume of 15% with cement weight, and the GGBS, with the weight of cement Fly ash has been replaced. Also, with the replacement of the fine aggregate by 5%, 10%, 15%, and 20% by the bottom ash. And the design mix of concrete was made the grade of M50. The strength of flexural, split tensile and strength of compression tests were completed on the standard specimen. Also, the characterizations of materials such as XRD, SEM, and EDAX have been performed. From the test results, the GGBS of 15% replacement with cement possesses good mechanical properties. From the characterization results, the materials have a good surface area and angular texture, providing good bonding with the ingredients
