Abstract: Self-compacting concrete (SSC) is concrete that can flow under its own weight to fill form work and produce a dense, homogenous material without vibration. It’s made with super plasticizers and stabilizers to increase its flowability. Self-compacting concrete (SCC) is a revolutionary technology that has transformed the construction industry. SCC eliminates the need for vibration during placement, ensuring improved durability, reduced labor costs, and enhanced surface finish. It is also known as flowable, self- consolidation and Non vibration concrete. It is enormously consistent and highly flowable, without the loss of stability, and more over it can flow due to its weight, fill the formwork and achieve complete compaction even in the presence of crowded reinforcement. In this project, the M40 grade is selected and tests conducted for self-compacting concrete are the slump flow test, V- funnel test, and L-box test. After conducting these tests, the mechanical properties like compressive strength, and split tensile strength are studied. In this study, cement is replaced with 5-15% silica fume, powder content sufficient amounts of fines (<0.125mm) preferably in the range of 400kg/m3 to 600 kg/m3 inclusive of sustainable quantities fine aggregate, and mineral add-mixture like fly ash to improve the desired strength. Durability tests in self-compacting concrete: water penetration test, chloride penetration, carbonation, electrical resistivity, ultrasonic pulse velocity
