RETRACTED: Effect of particle size of nanosilica on microstructure of C-S-H and its impact on mechanical strength

The present work is focused on the effect of particle size of silica on its early age reactivity and its impact on C-S-H microstructure and mechanical strength at the early and later ages of hydration. Two different types of commercially available silica i.e. Elk-microsilica (Elk-Si) (100–300 nm) and colloidal nanosilica (CNS) (8–15 nm) were used for the study. The lime silica reaction was carried out with a C/S ratio 2.0 and the reaction was...
