This study investigates the effects on mechanical and durability properties of concrete by including nano-silica, nano- titanium dioxide, nano-alumina. The mixes included nanoparticles in a range quantities, from 0.5% to 4% cement weight. Several experimental tests were performed, those for chloride permeability, workability, compressive strength, flexural strength. Compressive strength increased 40.5 MPa permeability decreased 1000 Coulombs, indicating an improvement durability, when nano-silica content was found be 3%. Nano-titanium dioxide nano-alumina also shown minor but noticeable improvement. A detailed SEM microstructural analysis demonstrates formation dense refined microstructure, lending credence claims improved properties. Results show that adding concrete, particularly increases its performance without reducing or durability.
