Abstract

This review paper reports the up-to-date developments concerning use of nano-materials in construction industry. In this paper, exhaustive research work done on the application of nanosilica in the concrete is reported along with their research findings on the enhanced properties of concrete incorporated with nanosilica. It is reported that nanosilica based enhances the mechanical and durability properties significantly. Compressive strength at as early as 3 and 7 days is increased by nearly 25-30%, with overall
strength improvement at 28 days is about 30-40%. Compressive strength at age after 90 days found to increase by nearly 15-20%. Setting times and workability are found to be reduced in nanosilica concrete due to its very fineness and high reactivity. The effect of nanosilica on the properties of standard to high strength grade concrete is found to be very high than ordinary grade concrete. Dense microstructure due to refined pore diameters by nanosilica particles proved to be excellent durable construction material
