The capacity to regularly and commercially make silica fume modified concrete that is flowable in nature but still cohesive, which results in high early and later age strength including resistance to harsh conditions, had a significant impact on industries. This investigation explores the characteristics of silica fume and how they affect the characteristics of recently-poured concrete. The strength properties of concrete have been examined when cement has been partially replaced by silica fume. Prior to studying the strength parameters of concrete with silica fume partial replacement, the compression testing machine (CTM) was used to study the strength parameters of concrete without any partial replacement. For both the cube and the cylinder, silica fume was utilised to replace 0% to 15% of the cement, by weight, at intervals of 5%. The results demonstrated that the compressive strength of the cube and split tensile strength of the cylinder were significantly affected by the partial replacement of cement with silica fume. Concrete gains strength quickly when its silica fume level is raised, and at 10% replacement, it reaches its maximum compressive strength. Like the split tensile strength, which grows up to 10% before beginning to decline under uniform load conditions of 2 KN, it starts to decline after 10% under conditions of 4 KN.
