Abstract: Self-compacting concrete (SCC) is a well-defined flowable material, and non-segregating concrete that doesn’t need mechanical vibration and has a capability to self-heal or compact itself by its own weight. Self-compacting concrete is categorized by a low yield stress, Designed Rheological workability (DRW), filling ability, passing ability, segregation resistance, high deformability and high durability as a High Performance Self-Compacting Concrete (HPSCC).In this paper mechanical properties of M30 grade concrete by partial replacement of cement with Nano-silica are studied. The results were obtained for compressive strength, split tensile strength and flexural strength at7days, 28days and 56days. It was observed that addition of Nano-silica increases the compressive strength at all replacements levels in comparison to control mix. Also, strength is much higher at the initial ages due to the reaction of unhydrated calcium hydroxide with Nano-silica.
