Effect of nano silica on standard concrete - an Experimental approach

The mechanical properties of the concrete can be improved by adding nanoparticles.This research investigates the mechanical strength and durability of nanomaterial concrete using nano silicon dioxide as partial cement substitute.M45 grade concrete with 1% -4% nano silicon dioxide and a water-to-cement ratio of 0.40 was tested.The optimal result was achieved with 4% nano silicon dioxide.Mechanical tests such as density, compressive, split tensile, flexural strength and microstructural analysis such as X-ray diffraction and scanning electron microscpe were conducted .
