Review on Performance of Nano Silica and GGBS Blended Self Compacting Concrete

Abstract

Abstract Concrete has a very significant impact on the atmosphere since Ordinary Portland cement one of the raw material during its production process produces carbon dioxide in large amounts. The impact of concrete structures on the environment may lessen by augmenting the robustness and resilience. The Nano-level arrangement of concrete may be altered by adding a tiny amount of Nano-silica (NS). Since NS forms a paste of calcium silicate-hydrate (C-S-H) through a pozzolanic reaction with calcium hydroxide, it has amassed significant attention when compared to other Nano materials by successfully densifying and strengthening the concrete’s matrix. The present review paper focuses on examining the effects of NS and ground granulated blast furnace slag (GGBS) in various concentrations on the fresh and mechanical properties of Self Compacting Concrete(SCC). It is predicted that this review article will yield fresh concepts for the beneficial use of NS and GGBS in the construction sector and for future research in the field.
