Abstract: This study investigates the combined effect of deploying Nano-Silica (NS) and Pine apple fibres (PF) on mechanical properties of hardened concrete. NS has been used as the partial replacement of cement by 0, 1, 2, 3, 4, 5 and 6% by weight, and Pine apple fibres are used as volume substitution by 0, 1, 2, 3, 4, 5 and 6%. In our present investigation, Pine apple fibres having 40mm length were used. Compressive strength and pulse velocity test values are determined by using various combinations of NS and PF. Nano-Silica, because of its small particle size, can modify the properties by altering the micro-structure of the concrete. A notable improvement is being noticed in the strength properties of concrete when NS is used by virtue of its high pozzolanic activity confirming the evolution of higher amount of C–S–H gel in the existence of nano-particles. The addition of NS to the concrete will improve the properties strength as well as durability to a great extent. On the other hand, the addition of pine apple fibres to the concrete results in the reduction of permeability and the improvement in the crack resistance eventually
