Abstract: The influence of Nano-Silica with Natural Hybrid fibers on various properties of concrete is obtained by replacing the cement with various percentages of Nano-Silica and adding of Natural Fibers. Nano-Silica is used as a partial replacement for cement in the range of 2%,2.5%, 3%, 3.5% & 4% for M25 mix and Experiments were conducted for various percentages of the fibres such as 0.5%, 1%, 1.5%, 2% & 2.5% by the weight of cement. Results indicate that the concrete, by using Nano-Silica powder, was able to increase its compressive strength and the tensile strength of the concrete was increased due to the addition of the fibres. The mechanical properties of the harden concrete were found by conducting tests such as compressive strength, flexural strength and split tensile strength for various percentage of the Nano-Silica With Natural Hybrid fibre content at the age of 7 and 28 days in the concrete
