A strong and stable construction appears to prefer high overall performance concrete. Industries produce a significant amount of spinoffs and wastes, such as fly ash, copper slag, silica fume, and others, which cause health and environmental issues due to dumping and disposal. The most frequently used additional cementitious material that results from the operation of an electrical furnace is silica fume. The concrete's water permeability and strength are affected by silica fume and fly ash. Fly ash and silica fume are excess characteristics of concrete. Concrete's mechanical and durability properties are both enhanced by the proper introduction of silica fume. Due to its affordability, durability, and ability to ensure safety, this type of concrete is employed in many large projects. Fly ash and silica fume have replaced cement in the range of 0%, 5%, 10%, 15% and 0%, 5%, 7.5%, 12.5%, respectively. The specimens has tested by compressive and split tensile strength.
