The study deals with the effect of Nano silica in concrete mix for improving its toughness characteristics like compressive and bond strength. In this investigation work nano silica in concrete is replaced 0% to 3% by weight of cement. Concrete cubes of size 150 × 150 × 150 mm for compressive strength and another specimen of size 150 × 150 × 150 mm with 16 mm diameter tor steel bar of length 650 mm embedded in concrete cube at the centre for bond test were prepared. All specimens are made according to the codal provisions and tested for 28 days of curing. The compressive, bond test showed the increment in its strengths as compare to control mixes.
