A Review of Effect on Compressive Strength of Concrete After Addition of Nano-Silica

Abstract

The research mainly focusing on the use of nanomaterials in concrete. Further researchers are continuing to improve the durability and sustainability of concrete and have realized significant increment in mechanical properties of concrete by incorporating nano-silica. The review paper summarizes the effect of nano-silica addition compressive strength on concrete. It provides the current development of application of nano-silica in paste, mortar and concrete. Finally, the future trend/potential and implication of nanosilica in cement-based materials is discussed. A great number of researches have been performed to understand the nature of nanomaterials and their effect on the properties of concrete. A number of Research & Development work dealing with the use of nanomaterials like Nano silica, colloidal Nano Silica (CNS), AlO3,TiO 2 , ZrO2,Fe2O3, carbon nanotubes (CNT) in cement based materials are discussed in the literature.
