The aim of the experimental investigation is to find the influence of Nano silica and Fly ash on strength properties of concrete. Fly ash concrete is considered as a green building material. The use of fly ash in concrete improves the properties of concrete in fresh and hardened state. In this research, Fly Ash and Nano-Silica are used as partial replacement of cement. The cement is partially replaced by 30% of Fly Ash and Nano-Silica in different proportions. The influence on compressive strength, split tensile strength and permeability of M35 grade concrete is investigated. The concrete made with 30% fly ash and Nano-silica 3% by weight of cement possesses more strength and durability characteristics due to improved particle packing and additional binding action of NS.
