The experimental work carries around the impact of investigation of Nano Particle like Nano Alumina (NA) and further more one of the beneficial cementitious (pozzolanic) material in cement to improve the mechanical properties of the concrete. Nano Particle and pozzolanic material is partially replaced by the weight of cementitious material into concrete. The experimental work examine was done on Nano replaced concrete were cured for 28, 56 and 90 days of water for various concrete mixes like M30, M40 and M50 to calibrate the mechanical properties of concrete like compressive strength, flexural strength and split tensile strength of concrete and also Non Destructive tests like UPV and Rebound hammer test on the hardened concrete. The workability and mechanical properties were also studied for the conventional and Nano replaced Concrete. Based on the experimental test results obtained the influence of Nano particle in concrete can be examined in both fresh and hardened state.
